The Battle for the Recapture of Bataan from 31 January to 8 February 1945, by U.S. forces and Allied Filipino guerrillas from the Japanese, part of the campaign for the liberation of the Philippines was waged to secure the western shore of Manila Bay to enable the use of its harbor and open new supply lines for American troops engaged in the crucial battle for the liberation of Manila. The Bataan peninsula's recapture also avenged the surrender of the defunct United States Forces in the Far East to invading Japanese forces in 9 April 1942. The rapid advance of U.S. forces heading towards Manila had strained the capability of their supply lines at Lingayen Gulf, which had so ably supplemented their push south on the capital, almost to the breaking point. While the capture of Manila was significant for both military and psychological reasons, the seizure of Manila Bay was crucial from a logistical point of view. Its harbor was in American hands but would remain unused unless the Bataan peninsula and the island of Corregidor in the west was secured.
