David was the son of John de Inchmartin. He held lands in
Inchmartine (now Inchture), in
Perth and Kinross. He was with Robert the Bruce at the
Battle of Methven. During the battle on 19 June 1306, David was captured by English forces under
Aymer de Valence, Earl of Pembroke. A number of Bruce's closest supporters were also captured. The Earl of Pembroke refused to summarily execute the prisoners as ordered by
Edward I of England. David was executed by hanging on 4 August at
Newcastle-upon-Tyne. ==Citations==
