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.
The world wonders "The world wonders" was a phrase used as security padding in an encrypted message sent from Admiral Chester Nimitz to Admiral William Halsey, Jr. on October 25, 1944, during the Battle of Leyte Gulf. The words, intended to be without meaning, were added to hinder Japanese attempts at cryptanalysis, but were mistakenly included in the decoded message given to Halsey and interpreted by him as a harsh and sarcastic rebuke. As a consequence, Halsey dropped his pursuit of a Japanese carrier task force in a futile attempt to aid United States forces in the Battle off Samar.
