The Battle of Ain Defla (Arabic: معركة عين الدفلى) was a major five-day-long battle from 26 to 31 March 1995 during the Algerian Civil War. It took place in the Ain Defla region when government forces ambushed 1,000 to 1,300[1]Islamist rebels. The Islamist rebels had a death toll of 600[2] to over 800,[3] with as many as a thousand in total on both sides.[2] Algerian newspapers described this as one of the worst rebel defeats in an area which they have controlled for months.[2]
