Battle of Luzon
The Philippines held a strategic value that threatened the United States when Japan captured it in 1942. General Douglas MacArthur oversaw the defense of the islands before being ordered to Australia. By October 1941, Imperial Japanese forces had stationed 135,000 troops and 227 aircraft within the region. Admiral Chester Nimitz and Admiral Ernest King opposed MacArthur's desire to retake the territory immediately. They argued that the campaign must wait until victory was certain. MacArthur waited two years for his wish to be granted. The island of Leyte became the first objective of the recapture campaign. U.S. forces secured Leyte by the end of December 1944. This success paved the way for attacks on Mindoro and eventually Luzon.
U.S. aircraft conducted reconnaissance and bombing flights over southern Luzon to mislead Japanese commanders. Transport planes dropped dummies via parachute to simulate an invasion from the south. Minesweepers cleared bays at Balayan, Batangas, and Tayabas while Filipino resistance fighters sabotaged positions. These tactics failed to convince General Tomoyuki Yamashita about the true landing site. He built significant defensive positions in the hills surrounding Lingayen Gulf instead. The actual assault launched on the 9th of January 1945 under the codename S-day. Approximately 800 ships formed the total Allied invasion force that month. Pre-assault bombardment began at 7:00 from roughly 70 battleships and cruisers. Landings commenced an hour later against strong opposition from kamikaze aircraft. The escort carrier was destroyed by a single attack while around 47 other ships sustained damage.
The largest tank battle between American and Japanese forces occurred from mid-January to early February. The Japanese 2nd Tank Division deployed 220 tanks including Type 97 ShinHōtō Chi-Ha medium models. They faced only 76 American tanks consisting of M4 Sherman and M5A1 Stuart light variants. Krueger held more tanks in reserve north of the front lines due to ambush threats. The Japanese hid their vehicles behind camouflaged fortifications or dug them into the ground. Some units patrolled and engaged enemies specifically during night hours. Fighting stretched from San Manuel to Muñoz over three weeks rather than one day. Hundreds of American soldiers died alongside thousands of Japanese troops during these duels. Dozens of American tanks were lost along with around 200 Japanese tanks.
U.S. forces entered Manila on the 3rd of February after capturing the bridge across Tullahan River. General Yamashita ordered his troops to destroy all bridges and vital installations upon entry. Paratroopers of the 11th Airborne approached the city from the south but halted by heavy resistance. The division captured the last outer defenses on the 11th of February thus encircling the entire city. Military casualties totaled 1,010 Americans and 3,079 Filipinos during the urban fighting. Over 150,000 civilians perished mostly during the Manila massacre of February 1945. These deaths were overwhelmingly committed by Japanese forces against unarmed populations. U.S. and Filipino forces conducted clearing operations throughout the following weeks in the devastated streets.
American planes dropped more than one million gallons of napalm to support ground forces across Luzon. The United States military used this weapon as a tactical tool during World War II. The name napalm remained classified so it attracted little attention outside official channels. Louis F. Fieser documented the scientific method behind the project in personal accounts. Brooks E. Kleber and Dale Birdsell recorded chemical usage statistics for the Office of the Chief of Military History. The weapon was deployed extensively to assist infantry units moving through dense terrain. Its use marked a significant escalation in firepower available to Allied commanders.
Allied control over strategic locations on Luzon was secured by early March 1945. Small groups of remaining Japanese soldiers retreated to mountainous areas in the north and southeast. They were besieged there for months while pockets held out until Japan's unconditional surrender. Total Japanese losses reached 217,000 dead with 9,050 taken prisoner. Only 2,000 troops from the Kembu group and 8,300 from the Shimbu group survived the war. Yamashita's Shobu group had enough food to sustain themselves for only one month after defeat. Almost all remaining men died of starvation or disease rather than combat. Civilian casualties are estimated at 120,000 to 140,000 dead throughout the campaign.
