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.
