The U.S. 11th Armored Cavalry Regiment, less its 2nd Squadron, withdraws from Vietnam. The “Blackhorse Regiment” (named for the black horse on the regimental shoulder patch) first arrived in Vietnam in September 1966 and consisted of three squadrons, each with three armored cavalry troops, a tank troop and a howitzer battery, making it a formidable fighting force. Upon arriving in Vietnam, the regiment had 51 tanks, 296 armored personnel carriers, 18 self-propelled 155-mm howitzers, nine flamethrower vehicles, and 18 helicopters.
While in Vietnam, Blackhorse conducted combat operations in the 11 provinces surrounding Saigon and participated in the Cambodian incursion in 1970. During its combat service in Vietnam, Blackhorse suffered 635 troopers killed in action and 5,521 wounded in action. Three of its troopers won the Medal of Honor for bravery on the battlefield.
Upon its departure from Vietnam, the group was sent to Europe where it was assigned to guard the frontier in West Germany. The regiment’s 2nd Squadron remained in Vietnam until March 1972, when it departed to join the rest of the regiment in Germany.
Also on this day: Premier Chou En-lai of the People’s Republic of China visits Hanoi. After lengthy consultations, Chou and North Vietnamese Premier Pham Van Dong issued a joint communique on March 10, which vowed continued Chinese support for the North Vietnamese struggle against the United States. This support was instrumental in providing the North Vietnamese with weapons and equipment needed for the major offensive they launched in the spring of 1972.
