At 0935 that morning (2 September), while the North Koreans were attempting to destroy the Engineer troops at the southern edge of Yŏngsan and clear the road to Miryang, General Walker talked by telephone with Maj. Gen. 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 U.S. 2nd and 25th Divisions. He described the location of his reserve forces and his plans for using them. He said he had started the marines toward Yŏngsan but had not yet released them for commitment there and he wanted to be sure that General 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.
Sometime today 9/1
General Hickey replied that General MacArthur had the day before approved the use of the marines if and when Walker considered it necessary.
A few hours after this conversation General Walker, at 1315, attached the 1st Provisional Marine Brigade to the 2nd Division and ordered a co-ordinated attack by all available elements of the division and the marines, with the mission of destroying the enemy 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 just as soon as this mission was accomplished. [24-15]
