I came through and I shall return." - General Douglas MacArthur
Those who had decoded and seen the Japanese communications in early December 1941 would not be surprised when they heard about an attack on December 7, 1941. They would, however, be astonished when they heard where that attack took place. Posted on the other side of the world, it was early on the morning of December 8 in the Philippines when American general Douglas MacArthur received news of the Japanese attack on Pearl Harbor hours earlier. With that, it could only be a matter of time before the Japanese attacked the Philippines.
Although MacArthur and Allied forces tried to hold out, they could only fight a delaying action, and the Japanese managed to subdue all resistance by the spring of 1942. In the wake of the 1941-1942 campaign, Japan occupied the country and went on to expand their territory in the Pacific, while at the same time destroying the American presence in that region, but by the spring of 1943, American military planners had begun to create a plan to dislodge Japan from east and southeast Asia. To do so, parts of the Philippines were considered main strategic points in the potential Allied attack in the Pacific. The end goal of the Allied plan was an invasion of the Japanese home islands, in which heavy aerial bombardment would precede a ground assault. In order for this to occur, Allied forces would have to occupy areas surrounding Japan.
By the time the campaign started, Japan was on the defensive, but as they would prove in other places like Iwo Jima and Okinawa, Japanese soldiers would act fanatically before admitting defeat or surrendering. During this second major Philippines campaign, an estimated 330,000 Japanese died, and only a bit more than 10,000 were willing to be taken prisoner.
