The Capitulation of Irvine was an early armed conflict of the Wars of Scottish Independence which took place on 9 July 1297. Due to dissension among the Scottish leadership, it resulted in a stand-off.
In May 1297, William Wallace killed William de Heselrig, the English High Sheriff of Lanark. At the time, it was not an isolated incident, although it is unclear whether this was a spontaneous occurrence or co-ordinated with other risings in Scotland. The story that Wallace was seeking revenge for the killing by Heselrig of his wife, Marion Braidfute of Lamington is derived from the poem by Blind Harry, The Actes and Deidis of the Illustre and Vallyeant Campioun Schir William Wallace.
Wallace then joined with William the Hardy, Lord of Douglas, and they carried out the raid of Scone. This was one of several rebellions taking place across Scotland, including those of several Scottish nobles and Andrew Moray in the north.
John de Warenne, 6th Earl of Surrey and Edward's warden in Scotland, sent his grandson, Henry de Percy, 1st Baron Percy with an army of 40,000 foot and 300 horse to deal with the insurrection.
On 9 July 1297, the nobles of Scotland gathered on the banks of a loch between Irvine and Bourtreehill House. They were prepared to go into battle against the approaching English forces and had made camp at Knadgerhill, on the north side of the loch. When the English arrived, they too camped on the side of the loch but on the opposite banks to the south.
