Directly to the north of Dutch Keiser's 2nd Division stood Hap Gay's 1st Cavalry Division, still holding the northwest sector. Gay's responsibility had been enlarged and complicated by Walker's decision to withdraw Michaelis's 27th IR Wolfhounds and Paul Freeman's 23d from the Bowling Alley. To fill that critical gap in the defense of Taegu, the 1st Cav had extended itself farther north and east and redeployed two of its regiments. Marcel Crombez's 5th CR remained on its positions east of Waegwan, blocking the Taejon-Taegu road, but Cecil Nist's 7th Cav had leapfrogged from the 5th's left flank to its right flank, and Ray Palmer's 8th Cav had come around to the right of the 7th Cav to block the Bowling Alley. Into the void on the left (or south) flank of the division, caused by the repositioning of the 7th Cav, Walker had temporarily deployed Freeman's attached 3/23 at Yongp'o, where the 2/7 had trounced the NKPA 10th Division, which was still opposite that place but was still mysteriously quiescent.[9-53]
The 1st Cav's front was very long by the usual military standards, but the division now had a little more manpower and artillery to cover its key roads and hills. In the last week of August three new American battalions arrived to bring the three regiments up to authorized strength. In addition to these, Gay could call on the two infantry battalions of the British 27th Infantry Brigade, which arrived from Hong Kong at about the same time and which Walker placed in reserve in hills on the division's south flank, behind the attached 3/23.
Altogether Hap Gay had at his call twelve numbered infantry battalions, backed by five artillery battalions the four normally serving the 1st Cav, plus the 9th FAB (155mm howitzers) which had come independently to Korea and which had been supporting the ROK 1st Division.
Inasmuch as the six "veteran" infantry battalions of the 1st Cav had suffered very heavy casualties in the July and August fighting, Gay warmly welcomed the three new American battalions. These had been hurriedly slapped together in the States and rushed to Pusan. Two of the three had had no field training; however, all were well equipped and well officered, and each contained many combat experienced NCOs. The units were:
