1st Provisional Marine Brigade
In the Second Naktong Bulge, the 1st PMB only had 4,290 men, because about 500 men were killed in a month of the war. They were getting ready to go to Pusan to escape to Japan, but they also joined other Marines in the 1st Marine Division that would attack Ichon. They could not come because they were about to fight in Naktong. General Walker called them to help the 2nd Infantry Division in Naktong, but Mcarhut didn't like it because it would anger the East Command. They still fought. The attack was a threat to the supply line around the place.
