Fought 1307 between the Catalan "Great Band," 9,500 strong, and the troops of Walter de Brienne, Duke of Athens, 15,000 in number. The Catalans surrounded their camp with an artificial inundation, into which the Duke's cavalry rode unsuspectingly, and were cut to pieces, de Brienne being amongst the slain.
