The Battle of Leyte Gulf occurred from October 23 to 26, 1944, and was significant as it was the largest naval battle in history, resulting in Allied victory and Japanese defeat including the sinking of four Japanese aircraft carriers and introduction of kamikaze tactics by Japan.
Step-by-step explanation:
The Battle of Leyte Gulf took place from October 23 to 26, 1944. This naval engagement was of extraordinary significance as it was the largest naval battle in history and the last major sea battle involving fleets in the Pacific during World War II. The United States forces' primary goal was to regain control of the Philippines, which was crucial for establishing bases to launch operations for the invasion of Japan and for securing routes for logistics and reinforcements.
The significance of the Battle of Leyte Gulf extends to the first organized use of kamikaze attacks by the Japanese, and the crippling blow dealt to the Japanese fleet. During this battle, the last four major Japanese aircraft carriers were sunk, signaling a decisive turn in favor of the Allies. General Douglas MacArthur's troops would go on to retake the Philippines, fulfilling his promise to return, and further pushing the Japanese forces back towards their homeland. This victory played a crucial role in weakening Japanese naval capabilities and providing the Allies with strategic advantages in the Pacific theater.
