The allied left-wing was composed of Catalan and Dutch troops under Count Atalaya. The right-wing was commanded by Stanhope and was composed of British and Austrian troops. Starhemberg was in charge of the center, which was mainly German infantry.
On August 20 at 08:00 an artillery-duel started which lasted until noon. In the afternoon, the battle was more or less a repeat of the Battle of Almenara. The Spanish cavalry attacked fiercely and were almost successful, but the allied troops stood firm.
Then the British and Austrian infantry counter-attacked and the Spanish army was pushed back. Thousands were killed or taken prisoner. Philip V only escaped disguised as an ordinary soldier and helped by a local miller.
