War Plan Orange
When the Japanese began landing at Lamon Bay on December 24, 1941, South Luzon Force was badly dispersed. The 41st Division (PA) on the west coast was in position, but elements of the 51st Division along the east coast were in the process of movement. Meanwhile, upon activation of War Plan Orange-3, the Southern Luzon Force was called to Bataan. BGen. Parker sent his division staff to relay to BGen. Lim, and movement only commenced when 41st Division staff officers were able to commandeer buses of the Pasay Transportation Company.
