Next came a discussion as to the nature of the Marine counterattack. Craig cited the risks and disadvantages of advancing on too wide a front. He suggested that the 2d Infantry Division specify the Marine objectives and allow him to attack in such formations as he deemed most effective. Keiser and his staff assented, and the Marine officers hurried back to the Brigade CP.
All-Out NKPA Offensive
Glancing at the big picture, there could be no doubt that the enemy was making an all-out effort to smash through the Pusan Perimeter. Late in August it became evident that he was massing troops. The blow fell in the early morning hours of 1 September. The direction of the main attack remained in doubt until that afternoon, when it was revealed as a bid for a breakthrough in the Naktong Bulge which would expose the Pusan-Taegu lifeline.
Despite heavy casualties of the past 2 months, NKPA overall strength was estimated as high as 133,000 men as the result of filling the ranks with hastily trained replacements. Thirteen infantry regiments, 3 security regiments and the remnants of the original 3 armored regiments were believed to be participating in the offensive.[329]

For 2 months the Eighth Army had been purchasing time with space, and the enemy realized that time was now fighting on the side of the United Nations. The first ground force unit sent by a member nation to reinforce United States and ROK troops was the British 27th Infantry Brigade, which landed and took over a sector early in September. But the enemy knew that other UN contingents had been promised.
The reorganized ROK army, moreover, had recovered from its early disasters and was giving a good account of itself in the northern sectors of the Pusan Perimeter. There the 1st, 3d, 6th, 8th, and Capital Divisions had not only maintained their tactical integrity throughout August but even delivered several counterattacks.[330]

The NKPA numerical superiority, in short, could not last much longer. It was now or never if the invaders hoped to batter their way to Pusan, and Pyongyang staked everything on a final offensive.
The brunt fell upon the United States 2d Infantry Division. Troops from four enemy divisions were identified on this sensitive front, well supported by armor and artillery. Within a few hours pressure became so great that EUSAK decided to send the Marine mobile reserve to the aid of the Army troops.
