What type of surety was the Earl of Pembroke who participated in the battle at Lincoln castle in 1217?
Battle of Lincoln (1217) The Second Battle of Lincoln occurred at Lincoln Castle on Saturday 20 May 1217, during the First Barons' War, between the forces of the future Louis VIII of France and those of King Henry III of England. Louis's forces were attacked by a relief force under the command of William Marshal, 1st Earl of Pembroke. Thomas, the Comte du Perche, commanding the French troops, was killed and Louis was expelled from his base in the southeast of England. The looting that took place afterwards is known as the "Lincoln Fair". The citizens of Lincoln were loyal to Louis so Henry's forces sacked the city.
