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.
L'Histoire de Guillaume le Marechal L'Histoire de Guillaume le Marechal (English:"The History of William Marshal") is the verse biography of William Marshal, 1st Earl of Pembroke (1146 or 1147 – 14 May 1219), written shortly after his death at the request of his son, William Marshal, 2nd Earl of Pembroke. The biography is composed of 19,214 lines, in rhyming octosyllabic couplets, and was written in the Anglo-Norman language. It is the major extant text documenting Marshal's life. It was written based on the surviving account of his squire John D'Erlay. It can be used to provide insight into the two English kings, Richard I and his successor John, both of whom William served. The single surviving manuscript of the work, dating perhaps from the second quarter of the thirteenth century, was once in the collection of Sir Thomas Phillipps, and is now housed at the Pierpont Morgan Library in New York City, under the catalog number M888.
