End of Japanese Naval Dominance

The four-day battle of Leyte Gulf in October 1944 marked the eclipse of Imperial Japanese naval power, the last sortie in force of the Imperial Navy, and the largest naval battle ever fought on the face of the earth.
It was separated in four parts, each carrying its own name: the Battle of the Sibuyan Sea, when U.S. carrier planes struck the IJN's Center Force and sank battleship Musashi; the Battle of Cape Engaño, where U.S. carriers destroyed the Japanese carrier force that had served as a deception; the Battle of Surigao Strait, where U.S. and Japanese battleships fought the last dreadnought engagement of all times; and lastly, the Battle off Samar, where the Japanese Center Force took to sinking the U.S. escort carriers defending the beachhead and were soundly defeated by miniscule forces.
Strategic Background
At the conclusion of the Battle of the Philippine Sea, the debate on the continuation of the war once more started. Two distinct factions were opposing each other: the Navy, led by Admirals Nimitz and King, vowed to take Formosa in the ultimate extension of island-hopping, neutralizing the Philippine Japanese Army garrison by air blockade. Formosa, sitting astride the seaways from the Dutch East Indies to Japan, would be the perfect base for economic strangulation of Japan and was capable of serving as base for the final attack on the Japanese home islands.
On the other side was General Douglas MacArthur, Commander of the South-west Pacific Forces, who had dedicated himself to recapturing the Philippines in 1942. He was convinced that military reasons alone should not dictate the primary objective of the next months, but also political considerations: MacArthur argued that leaving the Philippines in Japanese hands would be an irreversible loss of American prestige in Asiatic eyes (and obviously a blow to his own prestige, he did not say).
To resolve this conflict of interests, President Roosevelt came to visit senior American commanders in Hawaii in July 1944. Meeting with General MacArthur and Admiral Nimitz, the President listened to the arguments presented by each, and, being a politician in an election year, listened very closely to what MacArthur told him in a private discussion the day of Roosevelt's departure: should he elect to leave the Philippines alone, he had better be prepared for a negative reaction from American voters.
