Marines returned to Beirut during the 1982 Lebanon War on 24 August with the arrival of the 32nd Marine Amphibious Unit (later redesignated as 22nd Marine Expeditionary Unit) and the Multinational Force in Lebanon (MNF). As part of a peace treaty, the Palestine Liberation Organization was withdrawn to Tunisia, and the Marines returned to their ships. Due to increased violence from the still-ongoing Lebanese Civil War, President Ronald Reagan ordered the Marines to return on 29 September in the form of 2nd Battalion 8th Marines. Relieved by 3rd Battalion 8th Marines in October, the MNF increasingly drew fire from different factions. The United States embassy was bombed on 18 April 1983 in opposition to the MNF's presence; 1st Battalion 8th Marines was rotated in under the command of the 24th MAU. On 23 October 1983, the Marine barracks in Beirut was bombed, causing the highest peacetime losses to the Corps in its history: 220 Marines, 18 sailors, and three soldiers, as well as 55 French Paratroopers of the 1st Parachute Chasseur Regiment and 3 French Paratroopers of the 9th Parachute Chasseur Regiment in a near-simultaneous bombing away. As violence increased, public pressure mounted to withdraw forces from Lebanon. After an additional 24 American deaths, the Marines were ordered to leave and began on 7 February 1984, and finished on the 26th.
