On 19 October 1976, the Battle of Aishiya took place, when a combined force of PLO and a Communist militia attacked Aishiya, an isolated Maronite village in a mostly Muslim area. The Artillery Corps of the Israel Defense Forces fired 24 shells (66 kilograms of TNT each) from US-made 175-millimeter field artillery units at the attackers, repelling their first attempt. However, the PLO and Communists returned at night, when low visibility made Israeli artillery far less effective.
