Which event took place first, Operation Undertone or the Battle of Leyte?
Operation Undertone Operation Undertone was a large assault by the U.S. Seventh and French 1st Armies of the U.S. Sixth Army Group as part of the Allied invasion of Germany in March 1945 during World War II.
Battle of Sarimbun Beach The Battle of Sarimbun Beach was the first stage of the Japanese assault on Singapore in February 1942 during World War II. Sarimbun Beach, in the west of Singapore Island, was the area in which Japanese troops, under the overall direction of Lieutenant General Tomoyuki Yamashita, first attacked Allied forces. The commander of Allied forces in Singapore, Lieutenant General Arthur Percival, did not expect the Japanese to make their main attack in the west, and failed to reinforce the Australian 22nd Brigade, which took the brunt of the assault. The main Japanese objective to the immediate rear of Sarimbun Beach was Tengah Airfield.
