Yamashita divided his men into three defensive groups; the largest, the Shobu Group, under his personal command numbered 152,000 troops, defended northern Luzon. The smallest group, totaling 30,000 troops, known as the Kembu Group, under the command of Tsukada, defended Bataan and the western shores. The last group, the Shimbu Group, totaling 80,000 men under the command of Yokoyama, defended Manila and southern Luzon.

Yamashita tried to rebuild his army but was forced to retreat from Manila to the Sierra Madre Mts. of northern Luzon, as well as the Cordillera Central Mts. Yamashita ordered all troops, except those tasked with security, out of the city.

Almost immediately, IJN RAdm. Sanji Iwabuchi re-occupied Manila with 16,000 sailors, with the intent of destroying all port facilities and naval storehouses. Once there, Iwabuchi took command of the 3,750 Army security troops, and against Yamashita’s specific order, turned the city into a battlefield.
