Edward II left Scotland and returned to England to attend a session of Parliament. Gaveston was left behind at Bamburgh Castle where he was relatively safe from the Lords Ordainers.
Queen Margaret landed near Bamburgh Castle on the Northumbrian coast with a small army. The main castles in the area, Alnwick, Bamburgh and Dunstanburgh surrendered to the Queen.
The Earl of Warwick was put in charge of capturing the castles from the Lancastrian garrisons. Edward had to stay at Durham to recover from a bout of the measles. The castles were not attacked but cut off from supplies to starve the soldiers out. Just before the new year the Lancastrian soldiers surrendered and the Yorkists took control of Alnwick, Bamburgh and Dunstanburgh Castles.
Sir Ralph Percy, the constable in charge of Bamburgh and Dunstanburgh castles, defected and allowed the Lancastrians to take control. Alnwick Castle fell to the Lancastrians shortly afterwards.
