In short: On January 9, 1945, the U.S. 6th Army executed a massive amphibious assault on Lingayen Gulf. While the D-Day landings in Europe are often cited as the pinnacle of naval power, the sheer scale of the troop volume and the speed of the inland push in the Philippines rivaled the most ambitious operations of the war.

The invasion of Lingayen Gulf was the culmination of a strategic naval journey. From December 13, 1944, to January 13, 1945, Allied ships navigated a circuitous route through the Leyte Gulf, the Surigao Strait, and the Bohol Sea. This maneuver was designed to bypass Japanese defenses and position the fleet for a strike on Luzon. By the time Admiral Jesse B. Oldendorf’s force reached the mouth of the gulf, the ships had already endured a grueling period of kamikaze attacks, which sank 24 Allied ships and damaged another 67 across the Philippine theater.

The tactical execution of the landing was marked by a surprising lack of resistance. Despite heavy naval and air bombardments beginning on January 6, Underwater Demolition Teams found almost no beach obstacles and only a handful of mines. Intelligence from Philippine resistance may have overestimated the Japanese defenses, as the 6th Army landed on a 25-mile beachhead with minimal opposition. By the first day alone, more U.S. troops were put ashore at Lingayen than were landed on the beaches of Normandy on D-Day. Over the following days, 203,608 soldiers were landed, quickly securing the area and penetrating five miles inland.

However, the success of the landing masked a high cost of attrition. The subsequent Battle for Luzon became the highest net casualty battle for U.S. forces in World War II, resulting in 8,000 American combat deaths. The Japanese suffered staggering losses, with estimates ranging from 192,000 to 217,000 combat deaths, and potentially as many as 380,000 when including non-combat deaths from starvation and disease. This victory was also overshadowed by the horrific treatment of civilians, including the massacre of over 150,000 Filipinos in Manila in February 1945.

The operation also highlighted the evolving nature of naval warfare. The 'big blue blanket' of air cover provided by Halsey was essential as kamikazes struck the fleet. One notable incident involved the USS Ommaney Bay, which was struck by a Yokosuka P1Y kamikaze that bypassed the destroyer screen due to a lack of radar signals and the blinding glare of the sun. These tactics forced the Allies to balance rapid inland movement with the constant threat of suicide aviation, eventually turning Lingayen Gulf into a vast supply depot for the remainder of the war.
