On the way back from the north, Pembroke stopped in the village of Deddington in the Midlands, putting Gaveston under guard there while he went to visit his wife. The Earl of Warwick took this opportunity to seize Gaveston, taking him to Warwick Castle, where the Earl of Lancaster and the rest of his faction assembled on 18 June. At a brief trial, Gaveston was declared guilty of being a traitor under the terms of the Ordinances; he was executed on Blacklow Hill the following day, under the authority of Lancaster. Gaveston's body was not buried until 1315, when his funeral was held in King's Langley Priory.
