(June, 1979)

Israel on the night of March 14–15, 1978, launched a major invasion of southern Lebanon with 20,000-25,000 ground troops backed by tanks, artillery, fighter planes and gunboats. The operation was mounted notwithstanding a number of diplomatic moves to forestall an anticipated reprisal attack in reply to the March 11 guerrilla raid on Israel and despite assurances by the Lebanese Government that it was in no way responsible for the Palestinian action[see above].
