The Battle of Arsuf was a battle of which Crusade?

The Battle of Arsuf was a battle of the Third Crusade in which Richard I of England defeated the forces of Ayyubid leader Saladin.

The battle took place just outside of Arsuf (Arsur), where Saladin attacked Richard's army as it was moving from Acre to Jaffa. Following a series of harassing attacks by Saladin's forces, the battle was joined on the morning of 7 September 1191. Richard's army successfully resisted attempts to disrupt its cohesion until the Hospitallers broke ranks and charged; Richard then committed all his forces to the attack. He regrouped his army after its initial success and led it to victory. The battle resulted in the coastal area of central Palestine, including the port of Jaffa, returning to Christian control.
