 At 09 : 35 September 2 , while the North Koreans were attempting to destroy the engineer troops at the southern edge of Yongsan and clear the road to Miryang , Walker spoke by telephone with Major General Doyle O. Hickey , Deputy Chief of Staff , Far East Command in Tokyo . He described the situation around the Perimeter and said the most serious threat was along the boundary between the US 2nd and US 25th Infantry Divisions . He described the location of his reserve forces and his plans for using them . He said he had started the 1st Provisional Marine Brigade toward Yongsan but had not yet released them for commitment there and he wanted to be sure that General of the Army Douglas MacArthur approved his use of them , since he knew that this would interfere with other plans of the Far East Command . Walker said he did not think he could restore the 2nd Division lines without using them . Hickey replied that MacArthur had the day before approved the use of the US Marines if and when Walker considered it necessary . A few hours after this conversation Walker , at 13 : 15 , attached the 1st Provisional Marine Brigade to the US 2nd Division and ordered a co @-@ ordinated attack by all available elements of the division and the marines , with the mission of destroying the North Koreans east of the Naktong River in the 2nd Division sector and of restoring the river line . The marines were to be released from 2nd Division control as soon as this mission was accomplished .
