Philippines. At 2 AM, Japanese invasion of the island of Luzon begins in earnest. 43,000 troops (48th Division) and 90 tanks land in the Lingayen Gulf, 110 miles North of Manila. US submarine S38 enters the shallow shoals of Lingayen Gulf and misses 4 transport ships and 2 destroyers with 4 torpedoes at 7.10 AM. S38 then sinks Japanese freighter Hayo Maru at 7.58. The American defenses (North Luzon Force, composed mainly of poorly-trained and equipped Pilipino troops) are spread too thinly to put up more than token resistance. In addition to marching on Manila, Japanese troops will head North to link up with earlier landings at Aparri and Vigan. After flying 1350 miles from Darwin, Australia, 9 US B-17s bombers attack Japanese ships in Davao Gulf, Mindanao, and then land at Del Monte on Mindanao.
