World War II: Defense of the Philippines - Part 3

History of the Marine Corps

Japanese forces occupied most of Luzon, and US/Philippine forces withdrew south to establish a defensive line. 72 officers and 1173 enlisted from more than 50 organizations joined the 4th Marines. This made them one of the most diverse Marine units ever to have existed. Despite the additional reinforcements, many newcomers to the 4th were sailors and didn't have experience with ground warfare. Marines were stuck between a rock and a hard place. In addition to fighting off the enemy, they had to train new troops on the basics, including how to load a rifle.
