Close air support was provided for RCT-5 by the MAG-33 squadrons which had begun tactical operations at Kimpo on the 20th. Although they were still in process of moving to the airfield from Japanese bases, VMF-212 and VMF(N)-542 flew strikes in support of all three assault battalions. Of the two carrier-based squadrons, VMF-323 almost doubled its usual number of daily missions on 22 September.[367] [367] 1st MAW _SAR_, Annex Jig: Appendix Fox; Annex Item: Roger, Sugar. [Illustration: APPROACHING THE ENEMY MLR 5th MARINES--21 SEP] Just before nightfall, Lieutenant Colonel Murray directed 1/5 to pull back to Hill 68 with one company while holding Hill 105-S with the other two. This shift was made necessary by the fact that the KMCs had been compelled to withdraw to Hill 104, their starting point. As a consequence, the center of the line was more than 1,000 yards in the rear of the battalions on the right and left. The company on Hill 68 was to provide covering fires in the morning, therefore, when the KMC battalion would renew its attack in an effort to regain lost ground. _RCT-7 North of the Han_ On D-plus 8 the 1st Marine Division had its third rifle regiment in line for the first time. OpnO 9-50, issued at 1200 on 23 September, directed the 7th Marines (less 2d Battalion) to cross the Han into a zone of action in the rear of the 5th Marines. In response to verbal instructions and a fragmentary warning order the day before, the regimental headquarters and 3d Battalion crossed late on the morning of the 23d. Colonel Litzenberg set up his CP on the north bank at 1710, and his men had their first contact with the enemy the following morning. A 3d Battalion patrol ranging to the north of the battalion zone of action encountered an estimated 200 NKPA troops, and Marine air and artillery supported a successful attack.[368] [368] 1st MarDiv _SAR_, Annex Roger Roger. Division orders called for the relief of 2/7 on the 24th in the area northwest of Kimpo by the 2d Battalion of the 187th Airborne RCT, USA. The Marine unit was directed to cross the Han that afternoon, followed by the 1st Battalion, which had completed unloading at Inchon. It had been decided by the Division command and staff to give the 7th Marines time for shaking down instead of committing the newcomers immediately to the attack on Seoul. The regiment was assigned a series of five objectives along a ridgeline extending from the ferry crossing at Haengju on a gentle arc to a point north of the city. Protecting the north flank and rear of the 5th Marines was a primary mission, and Colonel Litzenberg was also directed to prevent the escape of the enemy to the northward.[369] [369] O. P. _Smith, Notes_, 251–252. _Attack Continued by RCT-5_
