James of Avesnes

James of Avesnes (also Jacques or Jacob; 1152 – 7 September 1191) was a son of Nicholas d'Oisy, Lord of Avesnes and Matilda de la Roche. He was the lord of Avesnes, Condé, and Leuze from 1171. In November 1187, James joined the Third Crusade as leader of a detachment of French, Flemish, and Frisian crusaders arriving by ship on the Palestinian coast near Acre around 10 September 1189. James and his men came as military reinforcements for the Siege of Acre. While leading his contingent of soldiers, the other main leaders of the siege was Guy of Lusignan and Henry of Champagne, neither of them gaining a dominant position in leading the siege.

At the Battle of Arsuf, James was thrown from his saddle and, after slaying fifteen enemy warriors, was himself cut down. The next day, a search party of Hospitallers and Templars found his body on the battlefield. It was taken back to Arsuf and buried there in a ceremony attended by Richard the Lionheart and Guy of Lusignan.
