attacks on the squadron. One 741st bomber was lost when a Luftwaffe fighter dove head-on into it. The Liberator continued on the bomb run and dropped its bombs on the target before crashing into the ground. Other fighters continued their attacks to within 100 feet of the group's planes. On this mission, the 742d Squadron suffered its heaviest losses of the war, with six planes lost to enemy action. Only one of the squadron's Liberators that reached the target returned safely. The 743d Squadron put nine bombers over the target but was the only squadron of the group to bring all its planes home. The group pressed its attack on an oil refinery at Moosbierbaum, Austria, for which it received a second DUC. The group provided air support to ground forces in Operation Shingle, the landings at Anzio and the Battle of Monte Cassino in the spring of 1944. It knocked out coastal defenses to clear the way for Operation Dragoon, the invasion of southern France in September. As Axis forces were withdrawing from the Balkan peninsula in the fall of 1944, the squadron bombed marshalling yards, troop concentrations and airfields to slow their retreat. It flew air interdiction missions to support Operation Grapeshot, the Spring 1945 offensive in Northern Italy. The group flew its last combat mission on 25 April 1945 against rail yards at Linz, Austria. Following the surrender of German forces in Italy, it flew some supply missions and transported personnel to ports and airfields for shipment back to the United States. Most of the air echelon returned to the United States, ferrying their aircraft in June. The 740th Squadron's ground personnel moved to Bari Airfield in July 1945, where they serviced the aircraft assigned to headquarters, Fifteenth Air Force. Many of the group's remaining personnel were transferred to other units in the 304th Bombardment Wing for shipment back to the United States, while the group remained in Italy, serving as a replacement depot. The last of the air echelon departed Italy in July and the group was inactivated on 9 September 1945. The group lost 118 aircraft. It suffered 147 killed in action, 268 Missing in action, 179 prisoners of war, and 169 wounded in action. On the other hand, the group claimed the destruction of 119 enemy aircraft.
