Battle of Leyte Gulf
The Battle of Leyte Gulf (23–26 October 1944) was the largest naval battle of World War II and by some criteria the largest naval battle in history, with over 200,000 naval personnel involved. By late 1944, the Japanese fleet had become much weaker than that of the Allied forces; it contained fewer capital ships (aircraft carriers and battleships) than the Allies had aircraft carriers in the Pacific.
