Which event took place first, Operation Undertone or the Battle of Leyte?
Battle of Leyte The Battle of Leyte in the Pacific campaign of World War II was the amphibious invasion of the Gulf of Leyte in the Philippines by American forces and Filipino guerrillas under the command of General Douglas MacArthur, who fought against the Imperial Japanese Army in the Philippines led by General Tomoyuki Yamashita from 17 October - 26 December 1944. The operation code named "King Two" launched the Philippines campaign of 1944–45 for the recapture and liberation of the entire Philippine Archipelago and to end almost three years of Japanese occupation.
American airborne landings in Normandy The American airborne landings in Normandy were the first American combat operations during Operation Overlord, the invasion of Normandy by the Western Allies on June 6, 1944, during World War II. Around 13,100 American paratroopers of the 82nd and 101st Airborne Divisions made night parachute drops early on D-Day, June 6, followed by 3,937 glider troops flown in by day. As the opening maneuver of Operation Neptune (the assault operation for Overlord) the two American airborne divisions were delivered to the continent in two parachute and six glider missions.
