The Ironclad Age, in the brief space of fifty years, saw the instruments of naval power progress in three crucial areas - hull design, propulsion and armament - at an unprecedented rate. Put briefly, it was a case of wood and sail and cannonballs to steel and steam and shells. It is scarcely any wonder therefore that discussion of the naval power of the period, both at the time and later, was and is dominated by materiel.  
There were countercurrents of course. Theoreticians, led by Colomb, Mahan and later Corbett, attempted to extract eternal verities from their studies of the role of sea power in history. But those studies were based, as they had to be, on the way the technology of the past was used, and the more perceptive publicists - including Mahan - were ready to admit that material developments could modify, if not upset, the strategic theories they had generated.  
The mainstream - and it was a stream whose course led through popular as well as informed and academic discussion - was awash with details of hull form and material, armour, main and auxiliary machinery, guns and later torpedoes1. Figures often acquired their own momentum and reputation. Competition both within nations and internationally was intense. 1 Both broadsheets and periodicals carried extensive coverage; see particularly The Times and Illustrated London News, passim. Navalists concentrated on material matters; the campaign in the Pall Mall Gazette in the 1880s carried great material detail, and Brassey’s Naval Annual and the works of Fred T.Jane, including The British Battle-Fleet (1912, republished by Conway, 1998) were avowedly materiel-based.

2 See A.D.Lambert, ‘The Shield of Empire’, in J.R.Hill ed.,
The Oxford Illustrated History of the Royal Navy
(OUP, 1995), pp.184-189.  
Apart from the fascination of continuous and often dramatic development of materiel, there were other good reasons for its primacy in the discussion of naval power.
In the global context, the numerical preponderance of the Royal Navy meant that other powers had the greatest difficulty in formulating any strategic or operational concept to cope with it. The Jeune Ecole in France deployed the most radical logic, but it was not matched by performance. For their part, the British saw no need to publicise their own strategic plans although, as Andrew Lambert’s recent work has shown2, these were more highly developed than earlier commentators gave credit for.
Then again, there were no major wars to test any operational or tactical plans that could be formulated. Such wars as there were might be intensively studied and indeed there is evidence that the more thoughtful senior officers, ship designers, politicians and publicists did so study them. But there were always three lurking caveats.
First, few of these conflicts directly involved the main force of the Royal Navy. In the whole of that 50 years only a few bombardments - of Kinburn in 1855, Japanese targets in 1863, and Alexandria in 1882 - entailed the firing of a British fleet’s heavy guns in anger. True, there was a host of amphibious or riverine operations, in the Ashanti, Zulu, Boer, Chinese, Japanese, Egyptian and Sudanese Wars3; but these were scarcely typical of the work the main fleets were meant to do. 3 See W.L.Clowes,
The Royal Navy: A History from the Earliest Times to 1900
(Chatham, 1997), Volume VII, pp. 91-561 for an exhaustive account.
That led into the second caveat. All wars are unique, but those of the Ironclad Age were more unique than most. They took place mostly in very special environments - estuaries, bays, rivers, semi-enclosed seas - which had a marked effect on their conduct and on the provision and use of materiel. Moreover, in the eyes of Victorians they tended to be conducted by funny little foreign fellows who either had antiquated equipment, or did not know how to maintain or use the modern equipment they had.  
In turn, that linked with the third caveat. Britain might not lead the world in technical innovation, and later in this paper examples will be given of some notable instances of caution, even foot-dragging. But Britain’s industrial capacity and institutional framework were such that she could move with ease, once a decision was made to adopt any technical development, to outstrip any rival. Consequently the lessons of other people’s wars, and of Britain’s own limited conflicts, were always subject to the reservation that, to most problems that had come to light, a new technical solution was already in the pipeline; or, alternatively, a new material development was around the corner which would radically modify the assessment of success or failure in a particular incident of a war just ended.  
All these considerations conspired to give a profoundly material, and markedly insular, emphasis to every discussion of naval power. British superiority in related fields - in particular, the increasingly admired quality of the British sailor4 - was taken for granted, but her preponderance in material had to be worked for and maintained, and that was the half-century’s main preoccupation. 4 John Winton,
‘Life and Education in a Technically Evolving Navy’, loc. cit. n.2, p.271.

(London, 1977).
This paper will, therefore, base itself too in material matters: not simply because of the theme of the Conference to which it was addressed, but because it is the only appropriate way to approach the period it covers. In doing so, it will be divided broadly into the three areas with which the subject was introduced: wood to steel, sail to steam, shot to shell, or in other words Hull Design, Propulsion and Armament. Of course they interacted; that was and is one of the fascinations of the topic. And of course all had their operational effects. Some enhanced the application of sea power, others tended to limit it. That dialectic, accelerator and brake, will be analysed as far as space and time allow.
 
 
Hull Design

The author of this paper is not a naval architect and is very conscious of treading on dangerous ground in this section. The technical detail of warship construction was exhaustively described, and argued about, at the time and the process has gone on ever since; those interested in going beyond this paper’s lay language are referred to the footnotes for further reading.
The first development in hull design of the Ironclad Age was, unsurprisingly, the cladding of warships with iron armour plate. This had first appeared in operational craft during the Russian War at the bombardment of Kinburn in 18555. Here, at the mouth of the Dneiper, the French - stealing a march on the British who were developing similar craft - deployed three ‘floating batteries’ which, protected by iron armour, were able to move in close to the Russian shore works and take a major part in battering them to pieces. They were able to do this at minimal cost in damage or casualties although repeatedly hit; the Russian projectiles bounced off or exploded harmlessly. 5 H.W.Wilson,

Soon afterwards the French Navy, urged on by Napoleon III to challenge Britain’s supremacy at sea6, embarked on its first large-scale ironclad, the Gloire, designed by the great naval architect Dupuy de Lôme. But the British, egged on by visionaries like John Scott Russell7, were already preparing something bigger and better: the Warrior.

This magnificent vessel, still happily afloat and superbly presented in the Heritage area at Portsmouth, was when completed in 1861 comfortably superior in fighting terms to anything else afloat. Iron-framed, her sides clad in 4 1/2 inch iron armour backed by two layers of teak, she was a monument to her chief designer Isaac Watts and her builders, Thames Ironworks at Blackwall8. Here at once can be seen the main pattern of warship design and construction in this period: Watts was an Admiralty employee, designated the Chief Constructor, but the builders were a private firm and engines and services were also from contractors. Later in the period the Royal Yards built a substantial number of ships but the proportion of any class so built was never more than half.
8 David K.Brown RCNC, Warrior to Dreadnought (Chatham, 1997) p.12.
The Warrior proved to be seaworthy, fast under power and indeed sail, though not too handy under sail alone9. She was followed through the early 1860s by a distinguished line of major warships on essentially the same plan, which perpetuated the end-to-end gundeck and full sail plan that were characteristic of the first half of the century. But already, under the new Chief Constructor Edward Reed, design was moving on and the centre-battery ship was evolved10. This concentrated the main guns, still on the broadside, towards the central section of the ship where they received maximum protection from the increasingly thick armour.

Reed also addressed a problem that had surfaced as soon as iron-hulled ships were conceived: if holed, they would sink much more readily than an all wooden vessel. For iron ships, watertight subdivison was clearly the answer, and Reed from the Bellerophon (1866) onwards increasingly concentrated on this aspect11.  
11 Brown, n.8, p.30.
He was right to do so, as events proved. The reason was not so much one of damage by the enemy - as we know, there was little enough of that - as by one’s friends; and the underlying reason for what we would now call blue-on-blue was a characteristic of hull design that is one of the most curious aspects of the ironclad period.  
This was the ram. From about 1870 onwards the majority of major warships, of all nationalities, were designed with ram bows. Only at the Battle of Lissa, between Austria and Italy in 1866, did a ram actually sink a major war vessel of the enemy12; yet it was persistently advocated by naval officers13 and influential members of the public, many of whom habitually referred to battleships as ‘rams’14. 12 Wilson, n.5, Battleships, p.53. Ramming was a predetermined tactic of both sides in that battle, and several attempts were made, but the sinking of the Re d’Italia was the only positive outcome.

13 Particularly Sir George Rose Sartorius: see Clowes, n.3, p.40.

14 For example H.G.Wells, in The War of the Worlds, where the Earth’s naval forces, steaming bravely towards the Martian war machines, are pulverised.
The reasoning was quite respectable. For the first time since the heyday of the galley, a warship was controllable independently of the wind and its adversary was vulnerable to being holed under water. Moreover, the alternative means of defeating an opponent - battering with gunfire - might well be ineffective against armour. Therefore, the ram.
That was the theory. In action it did not work. During the American Civil War attempted rammings occurred over and over again, but most of them were ineffective because the ramming ships were neither fast nor manoeuvrable enough to press their attack home15. The Re d’Italia at Lissa was conveniently stopped and broadside-on when rammed by the Ferdinand Max. All other sinkings were blue-on-blue.

The first was that of the Vanguard by Iron Duke in the Irish Sea on 1 September 1872. A sudden fog had come down; neither ship acted with due caution or sea-sense; and Vanguard was almost broadside-on when struck16. In spite of her 6-8 inch armour and watertight subdivision, she sank in relatively shallow water, all the crew being saved. A second and much more high-profile disaster was the sinking of the Victoria by the Camperdown on 22 June 1893 during a self-evidently dangerous manoeuvre17 ordered by the Commander in Chief Sir George Tryon, who lost his life in the accident.

A feature of the Vanguard and Victoria sinkings was that both victims were struck in a singularly vulnerable place, at the junction of a transverse bulkhead18. That might be thought bad luck; it was probably more germane that damage control on both occasions was defective. This may have been a legacy of the good old days of wooden warships, when watertight subdivision was not a feature; old habits die hard. In any event, the disasters were evidence of one operational penalty of ironclad vessels: they could sink.
18 Jane, The British Battle-Fleet , n.1, p.201; Brown, n.8, p.101.
That characteristic was not confined to ramming incidents. The introduction of turret-ships was another precursor of disaster. Defects in design and construction eventually - after her excellent introduction to battle in Hampton Roads - accounted for the American Monitor, which foundered in a seaway19. Her freeboard was minimal. So was Captain Cowper Coles’s fully-rigged Captain, a chapter of design faults with a vanishing angle of under 50 degrees, which turned over in a Bay of Biscay gale on 6 September 187020. 19 Brown, n.8, p.56.

20 Brown, n.8, pp.50-51;
Jane, n.1, p.197.
Better turret ships soon emerged. Even the fully-rigged Monarch was stable and seaworthy, though she did not handle well under sail alone. With the Devastation (1871) masts and sails were relinquished, though some later battleship designs continued to feature increasingly redundant sailing rigs. But the Devastation exhibited to a marked degree one of those notable characteristics of the mid-Victorian fleet: extremely low freeboard forward and aft.  
This was a direct result of the immense weight penalty imposed by armour that was still made of iron, compounded by the fact that machinery was still heavy and inefficient, and often rationalised by the argument that a low-lying vessel presented a more difficult target to opposing gunfire21. It meant that battleships in particular were not much use as gun platforms in most open-ocean conditions; particularly with the sea ahead or on the bow, the forward barbettes or turrets were impossible to fight and the after ones not much better. 21 General discussions of these problems are contained in Clowes, n.3, Vol VII, pp.25-28; Jane, n.1, pp. 209-214; Brown, n.8, pp.60-65.
 
This persisted through the 1870s and 1880s, the ‘Admiral’ class being noticeably unsuccessful in solving this part of the design problem22. But too much blame should not be imputed to Barnaby their designer. He was grappling with transitional problems of every sort. Steel was beginning to supersede iron but the compound armour that resulted was still suspect and subject to stringent testing. It was in fact the height of the armour-versus-armament battle in ship design, and controversy was made no less acute by strongly-expressed differences of opinion amongst naval architects, including previous and future Chief Constructors. To cap it all, money was tight23. 22 David K.Brown, ‘Wood, Sail and Cannonballs to Steel, Steam and Shells’ in J.R.Hill ed.,

No country was any more successful than Britain in solving the problems of the seventies and eighties. France was taking an average of nine years to complete a battleship24 and Russia and the United States were scarcely building at all. It is no surprise that operational capabilities went almost entirely untested throughout these decades; had they been, in an ocean environment particularly, the results could have been embarrassing to all concerned. One significant action that did occur, between the British cruiser Shah and the rebel Peruvian turret ship Huascar in 1877, ended with both ships still afloat and largely undamaged25. It may have been war in microcosm, but was still war, and ineffective in its outcome. 24 Brown, n.8, p.96.

25 Clowes, n.3, Vol.VII, pp.287-288.
Change was on the way. Steel for all sorts of marine fabrication, but particularly for armour, was becoming more readily available. The Harvey and Krupp face-hardening processes greatly increased the protection available for a given weight. The work of Froude was bearing fruit in many aspects of ship stability and hull form. Turret design and auxiliary machinery were more advanced as the nineties approached, and electric power plants were installed. The path was open for the advent of William White, who became Director of Naval Construction in 1886.  
White has been called ‘the greatest warship designer of all time’26. As has been suggested, he caught technology at the flood, and as he came into office the navalism begun by W.T.Stead in 188427 was gathering momentum that became unstoppable with the Naval Act of 1889. But it must be recalled that White was deputy to Barnaby in the difficult years of the late 70s and early to mid-80s; he had learnt in a hard school. 26 Brown, n.8, p.123.

27 Lambert, n.2, p.194.
The warships of the White era, which lasted almost to the end of the ironclad age, look right. Their freeboard is higher than that of previous classes, there is a proportion and balance about them, they are notably homogeneous, and their evident solidity suggests that if called upon to do battle they would have given a good account of themselves. Significantly, the only force with comparable looks by 1904 was the Japanese fleet that won the Battle of Tsushima.  
So hull design, by the beginning of the Dreadnought age in 1905, had solved most of the problems connected with material, stability and the utilisation of space. But it had been a difficult three decades between 1860 and 1890, and some of the hulls of that era must have behaved as oddly as they looked.
 
 
Propulsion

HMS Warrior steamed at 14 ½ knots. This was a step-change; previously, admirals had been accustomed to think of fleet speeds of advance of perhaps five or six knots, and if the wind was foul even that would be a struggle and only for the period that fuel stocks allowed. Now the possibility opened up of naval forces moving towards their objectives at up to ten knots. It would not happen overnight, but it was a reasonable prospect.
But as the broadside ironclads - Black Prince, Defence, Resistance, Hector, Valiant, Achilles, Minotaur, Agincourt, Northumberland - slid down the ways in the early to mid 1860s, they were still considered by many as sailing ships with auxiliary power. All carried full sailing rigs; indeed the Agincourt at one time had five masts, the most ever mounted in a warship28. Most had hoistable screws, to enhance manoeuvrability under sail alone. Little by little, however, captains and admirals were coming to rely on their machinery to keep them moving in the desired direction. 28 Ballard, n.10, p.24.
This trend continued in the centre-battery ships, Bellerophon (1865) and her successors. The midships grouping of the main armament enabled Reed, her designer, to produce a shorter, handier ship than the ‘Achilles’ type29; the penalty was an increased power:weight ratio and somewhat slower speed under sail alone. But she still carried three masts and a full rig, and was clearly designed to fight under sail if need be. 29 Brown, n.8, p.29.
Even the advent of turret-ships, Monarch and the ill-fated Captain, did not immediately wean the Admiralty away from a perceived necessity for sail. Both carried full sailing rigs and it was of course sail that aided the Captain’s capsize, even though her fundamental instability and lack of freeboard were the primary causes30. At this point in the design of warships the waning efficacy of sail and the penalties involved in continuing to provide for it became apparent. The masts of the Monarch, necessarily bulky and heavily stayed, were impediments to all-round fire and particularly to end-on fire, thought to be an important component of ramming tactics31. In the Captain it was sought to overcome this difficulty by fitting tripod masts, but these carried their own disadvantages. 30 ibid., p.51.

31 Even Jacky Fisher, when a young Commander in 1871, set out the line abreast for ‘ram or be rammed’ situations as one of the two basic tactical formations. See Arthur J. Marder, Fear God and Dread Nought (Jonathan Cape, 1952) p.80.
The solution was to bite the bullet and admit that turrets and full sailing rig were incompatible. It was much to the credit of Barnaby the designer, and Spencer Robinson the Controller, that the first ‘mastless’ battleship, Devastation, was in service by 1871. Henceforth sail in battleships, if fitted at all, was an auxiliary to steam power and not the other way about32 . 32 This certainly applied to the battle fleet. It was less clear-cut for cruisers. Lord Chatfield, a midshipman in the Cleopatra in 1888, records in The Navy and Defence (Heinemann, 1942), p.6, that the ship was ‘nearly always under sail’.

33 Wells, n.7, pp.220-222.
One of the developments that made this possible was the increasing efficiency of boilers and engines. The Warrior was fitted with a Penn two-cylinder single-expansion trunk engine33. Steam was supplied normally at 15 lb/sq in by up to ten smoke tube boilers. At 11 knots she consumed 3½ tons of coal per hour; at 14½ knots this figure rose to 9. Her total bunker capacity was specified by the Admiralty tender as 1000 tons but as built the ship carried a maximum of 853 tons. Even at economical speed, therefore, the Warrior would be hard put to get across the Atlantic under steam alone.
Over the next three decades efficiencies steadily improved in all aspects of steam propulsion. Two important non-technical governing factors must be recalled. First, engine and boiler design and manufacture were in the hands not of the Admiralty but of private firms of which Penn, Maudslay, Napier, Humphrys and Ravenhill were prominent. These competed eagerly for Admiralty contracts, and all aspects of performance - particularly standards of workmanship, reliability and timely delivery - were under scrutiny. Secondly, although many innovations were introduced by these firms, the Admiralty was unlikely to be first in the field to install them in new ships or classes. There is evidence in the Naval Estimates of the period34 that a great many trials were carried out under naval auspices, but the Admiralty much preferred that major claimed advances should first be tested in the intensely competitive merchant marine before they were incorporated in the fleet.35. 34 Bound copies in the Royal Naval Museum, Portsmouth for 1876-77, 1888-89 and 1898-99 have been consulted.

35 David K.Brown RCNC, ‘Marine Engineering in the RN, 1860-1905 - I’ in Journal of Naval Engineering, Vol.34 No 2 (June 1993), pp.398-9.
Advances there certainly were. In the field of steam engines, the cylinder-and-piston reciprocating engine experienced two major transformations, both involving the more efficient use of the steam supplied to it by the boilers. The first, the compound engine which superseded the single-expansion trunk engines, was a two-stage affair with high-pressure and low-pressure cylinders. The principle had been well understood since early in the nineteenth century and its theoretical advantages - fuel economy and less crankshaft wear - known, but only after about 1855 were installations made in the merchant fleet. The Admiralty conducted a trial in 1865 with results which, though less than conclusive, indicated greater efficiency in the compound engine, and by the early 1870s compounds were being installed in battleships, Dreadnought (1875) and Alexandra being the earliest36. 36 Brown, n.8, p.67.
The second great advance in steam reciprocating engines was an extension of the first - the addition of a third stage of steam utilisation to form a triple-expansion unit. Such engines were introduced in the merchant marine around 1880 and the Navy’s first installation was in the torpedo gunboat Rattlesnake in 188537. The first battleships to be so fitted were Victoria and Sans Pareil in 1889. It is worth noting that these were the fastest battleships so far built, at 17½ knots designed speed, but that was not the most important aspect of triple expansion, which was fuel economy, closely followed by reliability, durability and relative freedom from vibration. It is no coincidence that triple expansion engines were fitted in the Atlantic workhorses of the Second World War, the ‘Flower’ class corvettes and ‘Loch’, ‘Bay’ and ‘Castle’ class frigates. 37 ibid., p.99.
A graphic example of the advantages of triple expansion is given by the figures for the Thunderer, built in 1872 and modernised in 1889-90. On a measured run to Madeira - which seems to have been a favoured racetrack for such trials - the modernised ship consumed a little less than half the fuel she would previously have used38. Moreover, it was claimed that her original engines, even when new, would never have stood the strain of such a sustained run. 38 Brown, loc. cit. n.35,
Part II in Vol 34 No 3, p.657.
A final steam-engine innovation, though it comes only just within the timeframe of this paper, must be mentioned here. The steam turbine, invented by Parsons in the mid-1880s, was a working proposition by 1895 and in 1897 the experimental vessel Turbinia raced up and down the lines of the fleets assembled for the Diamond Jubilee Review at Spithead. It has been suggested that Sir John Durston the Engineer-in-Chief of the Royal Navy, far from being scandalised, had done much to encourage Parsons and was privy to the demonstration39. Turbine propulsion was quickly fitted thereafter to several classes of destroyer and its adoption for the Dreadnought (1905) sealed the package for all fast steam-driven ships for many generations. 39 Brown, n.8, p.183.
None of these advances could have been made without the development of boilers producing ever higher steam pressures and steadily improving steam quality. At the beginning of the period they were fire- or smoke-tube boilers; heat was transmitted from the furnaces via tubes led through the water in a box or cylinder, in order to produce steam which was then led to the engine. The basic feed was sea water, but the water in the boiler was in fact brackish; as it produced steam it became more and more briny and every few hours some of it would have to be blown down - with a consequent loss of boiler pressure - and replaced with condensate, pure water condensed from exhaust steam from the engine.
Boiler technology improved steadily through the 1860s to the 1880s, allowing increased steam pressures (Warrior 15 lb/sq in, Alexandra (1875) 60 lb/sq in, Thunderer (modernised 1889) 145 lb/sq in)40. It was helped not only by sophistication of design (particularly the cylindrical ‘Scotch boiler’) but by the increasing use of steel in boiler construction and the general introduction of the surface condenser which, by reconstituting exhaust steam more efficiently into pure water, allowed a pure boiler feed and obviated the need for frequent blowing down. 40 Wells, n.7, p.221 and Brown, loc. cit. n.35, pp. 648 and 657.
A boost to boiler power was provided by forced draught. This was a system whereby the stokehold was closed and air supplied by fans increased the atmospheric pressure, thus feeding the grate area and making the coal burn quicker with a consequent increase in steam pressure. Between 1880 and 1895 forced draught was a generally fitted feature41. It was not intended for routine use but for action or emergency conditions. In general the use of forced draught gave the ship an extra knot of maximum speed, at the expense of higher fuel consumption and more or less frenzied labour, in worse environmental conditions than under natural draught, for the stokers. There was some suspicion about forced draught throughout the naval community. Many voices suggested it was straining after a gnat. 41 Brassey’s Naval Annual 1888-9, p.57.
Fortunately relief was at hand in the watertube boiler. This was a reversal of the fire tube method; the principle had been proposed by Lord Cochrane, no less, in the 1840s but technical and material problems had held it up at that time. By 1880, however, Belleville in France had developed a working boiler, and this was fitted in all Messageries Maritimes vessels and adopted by the French Navy in 188942. The British were impressed and ordered 48 Bellevilles each for the massive fast cruisers Powerful and Terrible in 1892. 42 Brown, loc. cit. n.35, Part III, Vol. 35 No 1, p.96 ff.; Jane, n.1, p.278 ff.
These boilers delivered steam at 260 lb/sq in, a very marked advance on all previous installations. It was not achieved without a reliability cost. Technology was scarcely ready for such a high pressure system, and leaks leading to dramatic reduction in designed efficiency were widespread. The so-called Battle of the Boilers, in which the Bellevilles in particular and watertube boilers in general were criticised, lasted from 1901 to 1904. It has been contended by David K.Brown43 that the Belleville was unfairly dealt with, its shortcomings being due mainly to the proper procedures - developed by the French - being neglected. At all events, the Admiralty settled eventually on the Babcock and Wilcox and Yarrow as suitable watertube boilers for the Royal Navy, and the Yarrow was developed into the Admiralty Three Drum Boiler so well known to naval engineers between the two world wars. 43 Brown, n.8, p.165.
But for all the increases of efficiency in steam production and machinery during the Ironclad Age there was one enduring, pervasive factor: coal. It had two profound effects on strategic concepts, fleet operations and ethos: the first obvious, the second much less so.  
The obvious effect was on endurance. For sure, a warship propelled entirely or primarily by sail could not sustain unlimited sea voyaging; the governing factors were fresh water, fuel for cooking, and provisions, usually in that order. It is noticeable that in ships’ logs on prolonged voyages in the days of sail, the fresh water state is the one most carefully and systematically recorded. But a well stored and organised ship could manage several months at sea without calling for shore supply, although diet and living conditions would deteriorate and if the opportunity to replenish was offered, it would generally be taken.  
It was quite different for a warship whose primary means of propulsion was by steam. A battleship’s endurance even at economical speed was of the order of 6000 miles in the 1890s44. After that it must replenish with coal. The expense of coal was not a great problem; the wind was free, but coal was cheap. It cost less than £1 a ton in home waters, £1 10s in the Mediterranean. The total coal bill for the Navy in 1867 was £109,000, in 1888 £144,000, and it was only in the latter year that it outstripped ‘textile articles’ which included hemp and cordage45. 44 An average taken from Jane, n.1, Chapter XIII.

45 Naval Estimates for those years, Vote 10 Subheads C and D.
The problem lay much more in where the coal was, or was not. The Navy had since the introduction of steam power set up coal depots not only in home waters but abroad; in 1867 there were 26 depots, in 1888 29, of which 21 were outside the United Kingdom and included stocks at Shanghai and Nagasaki46. It is thus incorrect to say that coaling stations were simply an outgrowth of the navalism of the 1885-1900 period; they were a feature almost from the start of the ironclad age. 46 ibid.
What is undoubtedly true, however, is the way the perception of the limitations of coal supply was increased in the navalist era. It was then that purpose-built coaling stations were actively sought and acquired, under British rule, in such places as the Falkland Islands. The fleet, and in particular its scattered outliers the cruisers, could no longer bring itself to rely on coal stocks that might be vulnerable to foreign control.  
It was of course these considerations, and the limitation imposed by the paucity of overseas stocks before the network of stations was complete, that led to the retention of sail particularly in the smaller cruisers up to and including the 1890s. Contemporary accounts47 make it clear that many of these ships regarded themselves, and indeed were, sailing ships with auxiliary steam power rather than the reverse. How they would have acquitted themselves in battle, particularly against local forces operating close to their own ports and therefore with full mobility, is problematical. 47 Chatfield. n.34, pp.5-14; Admiral of the Fleet Sir Roger Keyes, Adventures Ashore and Afloat (Harrap, 1939) Chapters II-VIII.
It was the battle fleets that appeared to be most restricted in operations. The Mediterranean’s relatively small distances, like its usually benign weather, suited the fleets of the 80s and 90s, and home waters, the Channel and North Sea offered few problems, but in distant oceanic operations the battleships of those days would have had serious difficulties of endurance, seakeeping and maintenance.  
Replenishment at sea was not regarded as an option48. That was probably correct. Even a modern Fleet Auxiliary with a full array of transfer equipment would be hard put to conduct an underway replenishment of 1000 tons of solids (the average capacity of a 1890s battleship’s bunkers). The experience of the Russian Baltic Squadron, on its doomed voyage that ended at Tsushima in 1905, was indicative. They did sometimes have to replenish in open water, and so harrowing and infrequent was the occurrence that they carried as much additional coal as they could in every odd corner, including the upper deck, with disastrous effects on morale49. 48 Though on one celebrated occasion the commander of the weaker fleet in the annual manoeuvres took his force to the Canaries and coaled at sea there. He was widely thought to have cheated. See Gordon, n.17, p.253.

49 Richard Hough, The Fleet that Had to Die (Hamish Hamilton, 1958) p.75.
And that leads to the second, less obvious, limitation that coal imposed on the operational fleet. It was dirty.  
It is hard for us in the late twentieth century to gauge exactly the effect this had. The Navy of the Napoleonic Wars had been, if not fanatical, at least rigorous in its pursuit of cleanliness. Scrubbed decks, good ventilation, frequently washed clothes and bedding were features of every ship’s routine as reflected in their standing orders50. The practice had been continued into the long peace; indeed it probably had received added emphasis, not only because the incentives of fighting the enemy (and prize money) had disappeared and some other objective needed to be put in their place, but because in more remote areas such as the notorious West Africa Station, health and indeed life were thought, with some justification, to depend on it.
50 B.Lavery ed., Shipboard Life and Organisation 1731-1815 (Navy Records Society, 1998) pp.59-203..
Therefore, the advent of coal struck a shrewd blow at cherished naval practice and custom. Admirals were heard to mutter that since its introduction they had never seen a decently dressed or clean officer, let alone sailor. As for the ships, whenever steam was up they were constantly covered with smuts and after coaling they were filthy.  
The reaction was predictable. The challenge was met head-on, by an insistence on cleanliness that became almost an obsession. It probably reached its zenith (or nadir, if one follows the opposite persuasion) in the Mediterranean Fleet in the 1890s51, but was prevalent everywhere, not least in the suspicion with which exponents of the new arts - those of the destroyer man and the submariner - were viewed. These people simply could not keep themselves or their craft clean, however hard they tried, and many of them no doubt were regarded with the engineers as ‘rude mechanicals’. 51 Gordon, n.17, pp.175 and 304.
There can be no question, in the view of this writer, that a fleet obsessed with outside appearances must have serious operational shortcomings. The famous (and highly insubordinate) signal of Rear Admiral Percy Scott to his squadron ‘Since paintwork seems to be more important than gunnery …’ dates from 1907 and is indicative of the new, operationally-based thinking at the beginning of the Dreadnought era; but the change was long overdue, and it is anyone’s guess how the main fleets might have performed in action at the height of the spit-and-polish phase of the 1890s and early 1900s. All that can be said is that their likely opponents were probably equally fed up with the general nastiness of coal, and their operational efficiency was no higher than that of the Royal Navy even if their brightwork gleamed rather less.
 
 
Armament

The Warrior, when first commissioned, was armed on the main deck with thirty 68-pdr muzzle-loading smooth-bore cannon and eight 110-pdr Armstrong breech-loaders52. In addition she had upper-deck armament ranging from 110-pdr breech-loaders to 6-pdr cannon.
52 Data in this and the next three paragraphs is taken from Wells, n.7, Appendix 6.
This heavy and varied armament could deploy a very wide range of ammunition types. The 68-pdrs had the option of three sorts of shot - the traditional solid, case or canister, and grape - and three of shell - time fuzed powder or shrapnel, and Martin’s incendiary. The 110-pdrs were almost as versatile, with two shot and two shell options.  
Effective range and rate of fire had however changed little since the days of Nelson. A crack ship of the line of that era could manage three broadsides in five minutes. The Warrior, with large guns’ crews trained in the school that had been run in HMS Excellent since 1830, could manage one a minute, with the Armstrongs firing a fraction faster. As for effective range, the smooth-bores were little use outside a mile, while the Armstrongs could fire to a maximum of 4500 yards.  
All in all, then, the Warrior’s was a formidable and innovative battery, and combined with her armour and mobility it made her more than a match for anything else afloat. Pride, however, and there was plenty, was always tempered with caution, and it was caution that soon got the upper hand so far as arming the fleet was concerned.  
The main problem concerned the breech-loading guns. These were extensively tested during Warrior’s first commission and the general report was favourable, particularly on range and accuracy. But warnings were sounded about the dangers of premature explosion and accidents with the firing mechanism, and the Select Committee on Ordnance took note of them. Their fears were confirmed when at the bombardment of Kagoshima in 1863, 28 accidents were reported in a total of 365 rounds fired by 21 breech-loading guns53. These were, of course, from a number of different ships, none of them so well worked-up, nor manned with such picked crews, as the Warrior. 53 Brown, n.8, p.25.
But it was enough. The breech-loader, in its then form of a fully-screwed breech with vent tube firing, was suspect. In the Royal Navy for almost the next twenty years, the muzzle-loader resumed its dominance.  
For most of the period, it must be said, it was a much improved muzzle-loader. Rifling was introduced as early as 1865, studs in the shot or shell engaging in grooves in the barrel54. Iron rather than wooden carriages increased durability. Hydraulic machinery was introduced to absorb recoil and aid run-out, and to assist in loading. 54 Clowes, n.3, Vol VII, pp.45-46.
Towards the end of its reign the rifled muzzle-loader (RML) was in fact quite a sophisticated piece of kit. It could be accommodated in a barbette (a kind of armoured revetment with an open top, the guns turning inside it) or a turret (the now more familiar battleship mounting, roofed and trainable as a whole). In each case the loading arrangements were elaborate, usually entailing bringing the guns to full depression and often training them fore and aft as well. In drawings in the Illustrated London News it looked splendid and indeed, as the solution to a self-imposed problem, it was.
But the RML had inherent limitations. Its effective range, firing from its necessarily short barrel, could never be very great. In the 1882 bombardment of Alexandria, conducted almost entirely by muzzle-loaders, the mean range was of the order of 1200 yards and even then the effect of the shells - many of which did not explode - was much less than had been expected55, even though accuracy was high - as indeed it should have been at that range. Moreover, the RML was not well adapted to the new and more powerful propellants that were being introduced at the start of the 1880s; a fatal explosion in the Thunderer, due to double-loading, showed that the RML could be more dangerous than the BL; its rate of fire, however ingenious the loading arrangements might be, was never going to approach the potential of the BL; and finally and decisively, other nations and particularly the French had been using breech-loaders for come years and the British were lagging behind56. 55 Brown, n.8, p.72.

56 Ropp, n.6, pp.102-4.
As was usual in this period, once the British had decided to catch up they did so with impressive speed. The 12 inch and 13.5 inch breech-loaders introduced during the 1880s were successful designs (the 16.25, in the Benbow only, was not) and could be produced in considerable quantity, so that by the 1890s the British were comprehensively outbuilding, outarming and outnumbering the French and Russians.  
Some aberrations persisted. There was, as it would seem to us today, an absurd obsession with end-on fire57. This was partly due to a simplistic emphasis on the offensive, but was rationalised by residual reliance on the ram as a weapon. If you were going for your enemy’s soft underbelly, you needed to shoot at him on the way in. In the later centre-battery ships this had entailed recessed ports for some of the guns which thereby, in theory, could fire right ahead. In fact, as in the Alexandra, these guns were so wet in any sort of head sea that they could be fired only with the greatest difficulty58. In turret and barbette ships, shorn of any sailing rig, right-ahead fire was designed in - but only at the expense of a low forecastle which in turn meant washing down in a head sea, which in turn made firing and loading difficult. The attractions of the ram had much to answer for. 57 Jane, n.1,
Chapters X-XIII passim.

58 Brown, n.8, p.36.
Ammunition, and its handling and stowage, was always a worry and became more so as propellants and shell fillings were increasingly powerful and volatile. At the bombardment of Alexandria the Gunner of the Alexandra earned a VC for dowsing an incoming shell in a bucket of water59; in doing so he probably saved the ship, since the shell had landed in the long ammunition path between the magazine and the central-battery guns. In later designs, particularly the barbette and turret ships, the layout was more logical, with magazines and shellrooms situated beneath the mountings and under armour, but the problems were never entirely solved as the losses at Jutland - and several harbour accidents before and after - showed. They were not confined to the Royal Navy; the French Iena was similarly lost in the 1890s and many historians contend that USS Maine, whose explosion in Havana started the Spanish-American War in 1898, blew up from the same cause. 59 Clowes, n.3, Vol VII, p.331.
The gun armament situation was complicated from about 1880 onwards by the increasing tendency to fit a comprehensive secondary armament. This ranged from 9.2 inch guns supplementing the 12 inch in some battleships, to Nordenfelt and Maxim 0.45 inch machine-guns, and including a gamut of calibres and designs most of which could be designated as quick-firers.  
A principal reason for this proliferation of above-water weaponry - which was not confined to battleships but was a characteristic of cruiser types as well - was the advent of a new menace to ships that had previously worked on the principle that like fought like: the torpedo.  
‘Torpedo’ was at first the generic name for any underwater weapon. The mine, contact or controlled; the spar torpedo, carried on the bows of a suicidally-inclined small boat; the towed torpedo, pulled equally suicidally across the path of an advancing vessel; and the locomotive torpedo, perfected by Whitehead at his factory in Fiume, all made their appearance between 1855 and 187060. Only the first and last-mentioned survived as viable weapons. 60 Rear Admiral E.N.Poland, The Torpedomen (Kenneth Mason, 1993) pp.11-14.
The mine, as is well known, proved in the twentieth century to be a highly effective inhibitor of seaborne traffic in ports and coastal waters. In the nineteenth, its value in this role was recognised only spasmodically; mines both crude and sophisticated were laid during the American Civil War61, but it was not until the Russo-Japanese War of 1904-5 that they were used systematically on a large scale62. In the Royal Navy, neither mining nor mine countermeasures occupied a prominent place in planning or thinking. Indeed, the technology of the Hertz horned mine was common knowledge for 40 years before it was developed in Britain63; and the passage of the Dardanelles in 1878 and the bombardment of Alexandria appeared untrammelled by any consideration of a mine threat. It was perhaps fortunate for Britain that her ‘Cherbourg Strategy’ of the 1870s was never put to the test; but maybe in any case it would have worked, because the French seemed to be as little interested in mines as the British. The Russians, on the other hand, were known to be better provided, and the one British exercise with a serious mine threat incorporated - Berehaven in 1885 - was in a Kronstadt setting64. 61 Wilson, n.5, Ironclads, p.104, assesses that 32 Northern ships were sunk by mines during the war, as against three by ramming (one blue-on-blue).

62 Wilson, n.5, Battleships, pp.195-200.

63 Poland, n.59, pp.59-60.

64 Brown, n.8, pp.84-5.
By contrast, interest in the locomotive torpedo was intense. Opinions differ on whether Whitehead, an Englishman, could have been encouraged to return to Britain in the late 1860s from Fiume; he had after all worked on the continent for some years. What is certain is that he first offered his design to the Austrians65; when they were reluctant the British took it up and paid £15,000 for the non-exclusive rights to manufacture on Whitehead’s principles. The French made a similar purchase a year later, in 1873. 65 Poland, n.59, pp.14-19.
Both nations embraced the new weapon with enthusiasm, but it was the French to whom it gave greater leverage. As the weaker naval power, they saw a twin requirement to protect their bases and attack enemy commerce, and both these missions, it was thought, would be helped by torpedo craft. All kinds of idea were tried: battleships fitted with torpedoes as supplements to the ram, mother-ships fitted to carry torpedo craft to remote areas, and of course numerous torpedo craft to deploy their weapons in the harbour defence role.
The British, soon manufacturing torpedoes in the ordnance factory at Woolwich as well as buying them from Fiume66, adopted many similar ideas. Driven by the advocacy of Jacky Fisher, in charge of torpedo development at Excellent from 1872-6 and then hiving off to set up a separate school at Vernon67, the Royal Navy fitted torpedoes in both standard and specialised vessels. 66 Brown, n.8, p.86.

67 Captain John G.Wells, Whaley (HMS Excellent, 1980), p.27.
The first of the latter was the Lightning, a prime example of collaboration between Admiralty and private industry, built and engined by Thornycroft in 187668. She was followed by a generation of boats which, while suitable for sheltered waters, were inadequate in a seaway. Size inevitably increased, but so did the scale of the countermeasures. These were in two main forms: the diversity of secondary armaments in major units, and the evolution of gun-armed smaller vessels to catch and destroy torpedo-boats - the destroyers, which were themselves soon armed with torpedoes as well. 68 Brown, n.8, p.85.
It is in this class of ship, building from 1892 onwards, that can most clearly be seen the effects of intense competition between a large number of firms as moderated and modified by the Constructor’s department in the Admiralty. Designs were diverse amongst the builders involved and so were armaments, propulsion units and accommodation, but some commonality was achieved through the efforts of Henry Deadman, Assistant Director of Naval Construction69. There was constant striving after speed, often to the detriment of structural strength, machinery reliability and seakeeping. How effective these early destroyers would have been in a fleet action under ocean conditions is uncertain. What is sure is that they fostered in their officers and ratings an élan that the late Victorian Navy needed70.

Test Beds

The half-century under discussion was a great age for inventors. The application of previously discovered scientific principles was in full swing. Inventors generally worked in very small units; for projects promising success they either formed larger companies themselves or sold their techniques to engineering or construction firms.
 
The Admiralty’s part, under the Controller of the Navy, was to encourage, test and co-ordinate; the end-product being whole-ship design under Admiralty control. Apart from one or two isolated units such as Froude’s testing tank71, there was no state-sponsored research and development establishment. Information exchange was liberal; there were remarkably few secrets either state or commercial. This system, loose indeed by the standards of post-1945 Britain, enabled rapid progress to be made once innovation had been decided upon. As has been shown, such decisions were taken with caution; often in hindsight the caution was excessive, but the system mitigated its worst effects. And several kinds of test bed were available. 71 Brown, n.8, p.70.
The first was the experience of foreign navies. It has been claimed that the French were first in the field of armoured warships; steel fabrication; breech loading guns; fast torpedo craft; and water tube boilers72. The Americans were first in general use of the ram and operational application of the turret principle. 72 Ropp, n.6, pp.64-8.
These claims are, by and large, correct. Sometimes the priority gained by foreigners was due to advanced technology as in the case of steel production, sometimes forced on them by necessity as in the American Civil War, sometimes through excessive caution by the Admiralty as in the case of the breech-loader. But in every instance, except arguably that of the Belleville boiler, the Admiralty and industry learnt from the experience of foreigners and the Royal Navy benefited from the rapid introduction of the, to them, new technologies that resulted.  
The second test bed was the British shipbuilding industry. This was probably the most competitive industry in the world, arguably (though it is hard to measure) the most competitive there has ever been. There was constant striving for more speed and efficiency; mail steamers, cargo ships, windjammers and private yachts were alike subject to unrelenting development in machinery, construction and hull form. All this formed the stuff of regular discussion amongst naval architects and engineers, and the Navy benefited particularly in its propulsion units.  
It should be remembered that British firms built a great many ships for foreign navies from the keel up. An American commentator in 1878 said ‘Nearly every considerable naval power, except the US and France, has employed English designers, English ship builders, engineers and gun manufacturers’73. And in 1905 the Japanese fleet, homogeneous and balanced, had been built very largely in Britain. The cross-fertilisation between British industry, its foreign clients and the Royal Navy benefited all three. 73 Chief Engineer King, USN, The War-Ships of Europe (Griffin, Portsmouth, 1878), p.1.
 
The third test bed was the Controller’s Department itself. Under its sponsorship vast numbers of trials were conducted74. The most dramatic were of projectiles against armour. Stringently-controlled trials took place at Shoeburyness75, at set ranges against carefully-constructed replications of existing or planned armour and backing. Others were conducted against waterborne hulks, and on some celebrated occasions took the form almost of international competitions. They were minutely reported in the popular press76 and discussed in technical fora77. 74 See eg the Naval Estimates for 1888-9: well over 50 trials are listed.

75 Brown, n.8, passim; see particularly his quotation from Barnaby, p.79.

76 See eg The Illustrated London News, 30 June 1866, 13 July 1872.

77 Transactions of the Institution of Naval Architects, 1866, pp.13-14.
Not far behind were trials of torpedoes, which began as soon as the weapon was developed. They embraced not only the lethality of the torpedo in its various versions (including the mine)78, but defences against it; the evolution of the torpedo net, for good or ill, emerged from such tests. The torpedo department was also responsible for electrical devices of all sorts, and these too were subject to a whole gamut of sea trials79.
78 Poland, n.59, pp.18-25.

79 Estimates, n.74.
Speed trials were of course conducted on all new-construction ships. These showed the reverse side of the competition coin. Striving by the builders for the designed speed, or for an extra half-knot over it, led to all kinds of unrealistic shifts that had no relation to operational conditions80. They might mislead the public but were unlikely to deceive the Admiralty. Nevertheless they were a kind of yardstick; if everybody cheats, the playing field is arguably even.
 
80 See Jane, n.1,
Chapters XII and XIII.
Jane distinguishes clearly between performance on trials and subsequent success as ‘good steamers’ in service.
 
 
Concluding remarks

Of the five decades covered by this paper, the first four were marked by technological turmoil in the fields of warships’ hull design, propulsion and armament. Often progress resembled the fabled frog’s climb up the well: three jumps forward, two slips back. In the final decade, to conclude the analogy, the last three jumps took the frog out of the well and landed it on the (fairly) level grass of the White era. It then had to work out how best to manage its new environment, a job it took ten years even partly to solve.

The Royal Navy remained dominant in the world mainly through its numerical superiority, its demonstrated confidence, and the ability of British industry to respond to its demands for new construction. British design was not always in the forefront of innovation, British equipment even less so, but once a decision had been made the incorporation of new methods and devices was rapid.

Nevertheless, the operational shortcomings of the main fleet during the 1860s, and even more in the 1870s and 80s, were such that it was fortunate to go untested by war. Ocean-fighting capacity in particular was highly suspect. That other navies were even less capable, in both design and numbers, might have been of little significance; the most likely outcome of an ocean campaign would have been indecisive and spasmodic encounters, and an ineffective use of seapower. It is ironic that during this period, the dogma of the decisive sea battle emerged as the centre of seapower theory.

Where the new technologies did help decisively was in the operations it is now fashionable to decry, that led for good or ill to the extension of the British Empire into the Middle East, Africa and East Asia. Here a multitude of amphibious and riverine expeditions could scarcely have taken place without the mobility conferred by steam propulsion, the protection given by (often improvised) armour, and the superiority of firepower.

The confidence, resourcefulness and energy displayed by the Navy (and the Royal Marines and Army) in these operations may suggest that, if subjected to the test of full-scale war, the battle-fleet would have been quickly brought to a state of much higher fighting efficiency than it seemed to show in peace. After all, there were not two navies, main fleet and expeditionary, but one; officers and men moved freely from gunboats to battleships. Nevertheless, the material shortcomings of the larger ships, for their primary ocean-going role, must cast doubt on the battle-fleet’s effectiveness if called upon.

The Navy’s organisation for procurement of materiel was at least as efficient as those of its continental rivals. The formation of professional bodies - the Institution of Marine Architects in 1860, the Royal School of Naval Architecture in 1864, the Royal Corps of Naval Constructors in 1884 and the Institute of Marine Engineers in 1889 - made the exchange of ideas easy and the spirit of the age ensured it was vigorous. The Controller’s ability to place contracts was aided by the large number of firms able to tender in a highly competitive market.

The synergy of the system was a prime example of the robust structures described by Paul Kennedy in The Rise and Fall of British Naval Mastery. In hindsight, as Barnett and Kennedy himself have pointed out, Britain was already faltering and overstretched, and other industrialised or industrialising powers were poised to overtake. But it was not apparent at the time. Britannia ruled.
