The Japanese had determined tha they must defend their positions on Leyte, regardless of the cost. On the10th of November 1944, a furious fight took place at Ormoc Bay when a Japanese Reinforcement convoy was caught by elements of the 5th Air Force, including B-25Js of the 822nd Bomb Squadron, 38th Bomb Group. Nine Japanese ships were sunk and four were damaged, but at a high cost. Seven U.S. aircraft were shot down and eight were damaged.
