Ernoul

Ernoul was a squire of Balian of Ibelin who wrote an eyewitness account of the fall of Jerusalem in 1187. This was later incorporated into an Old French history of Crusader Palestine now known as the Chronicle of Ernoul and Bernard the Treasurer (), often abbreviated Ernoul-Bernard. The chronicle covers the years from 1100 until 1228. A few manuscripts copied for Bernard, treasurer of Corbie Abbey, extend the narrative down to 1232.

==Authorship== Ernoul himself is mentioned only once in history, and only in his own chronicle. He was a squire of Balian of Ibelin, an important crusader noble in Jerusalem, and accompanied his lord on an embassy from King Guy of Jerusalem to Count Raymond III of Tripoli in 1187. Balian and his retinue remained behind for a day at Nablus during the voyage to Tripoli; the rest were ambushed at the Battle of Cresson on May 1. It was Ernoul who investigated the almost-empty Templar castle of La Fève before news of the battle reached Balian. No other mention is made of Ernoul. However, it is clear that he was at the Battle of Hattin on July 4, as his chronicle gives an account from the rearguard, which was commanded by his master Balian.
