Later that same day the 17th ROK Regiment, under the control of the 7th Infantry Division, crossed in the LVTs. It was hoped by United Nations leaders that this unit, known as the Seoul Regiment, could take part in the liberation of the ROK capital. Apparently the second river crossing of the day alarmed the enemy, for it drew mortar and artillery fire in greater volume and accuracy than had been encountered before. The support given to the two crossings by the 1st Amphibian Tractor Battalion was commended by General Barr in a letter to General Smith. “Despite long hours, loss of sleep, maintenance difficulties, and exposure to fire,” said the commanding general of the 7th Infantry Division, “the personnel of your battalion performed so magnificently that I have nothing but praise to offer. If at any time in the future elements of this Division are called upon to cross a river, it is my sincere wish that they may be supported by the 1st Amphibian Tractor Battalion.”[405] [405] MajGen D. G. Barr (USA) ltr to MajGen O. P. Smith, 5 Oct 50. From South Mountain the troops of the 32d Infantry looked down upon the city. They could not enter as yet because of the danger of interfering with the fires of the 1st and 5th Marines. But the 32d and the ROK unit were assigned a zone of action by Corps for an advance on the right of the Marines when the time came for a concerted effort. _Division Attack of 25 September_ At 0700 on the 25th the 1st Marine Division launched the final phase of its attack on Seoul. The following objectives were assigned by Division OpnO 11-50: RCT-1, with the 2d KMC Battalion attached, was to seize the part of Seoul within its zone of action and Objective ABLE, consisting of the high ground beyond the northeastern outskirts and about six miles from the jump-off positions. The zone of action, ranging from a mile to a mile and a half wide, carried the attack through the heart of the city, with South Mountain on the right and Ducksoo Palace on the left. Mopping-up operations were assigned to the KMCs, who would revert to their own regimental control afterwards. RCT-5, with the Division Reconnaissance Company and 1st KMC Battalion attached, was to seize that part of Seoul within its zone of action and Objective BAKER, comprising the high ground overlooking the Seoul-Uijongbu road six miles from the line of departure. About a mile and a half wide, this zone included the northwest section of the city and the Government Palace, though the regiment would be operating in open country after an advance of about two miles. The KMCs were to be used for mopping up after RCT-5. RCT-7 had the mission of protecting the left flank of the Division and seizing Objective CHARLIE--the high ground astride the Seoul-Kaesong road about six miles northwest of the center of Seoul in the vicinity of Chonsong-ni.
