Answer
Westmoreland commanded U.S. forces in Vietnam for four years, from 1964 to 1968. During his tenure, he oversaw the escalation of the war, including the deployment of hundreds of thousands of additional troops and the launch of major offensives against the Viet Cong and North Vietnamese forces. Westmoreland's command was marked by both successes and setbacks, and he ultimately left Vietnam amidst growing controversy over the conduct of the war.
