 However, due to the lack of sufficient manpower, Welch suggested that Allen should either call off the assault or get more soldiers on the ground for the operation.Allen dismissed Welch's suggestions, and responded by giving Captain James George—commander of Company A—the responsibility of leading the attack instead of Welch.Meanwhile, the 1,200-strong 271st Regiment was joined by 200 soldiers from the C1 Company of Rear Service Group 83—under the command of Captain Nguyen Van Lam—and they set up a three-sided ambush and waited for the arrival of a reported U.S. battalion.
