Battle of Fire Support Base Ripcord
The Battle of Fire Support Base Ripcord was a 23-day battle between elements of the U.S. Army 101st Airborne Division and two reinforced divisions of the North Vietnamese Army from July 1, 1970 until July 23, 1970. It was the last major confrontation between United States ground forces and North Vietnam of the Vietnam War. Three Medals of Honor and six Distinguished Service Crosses were awarded to participants for actions during the operations.
President Nixon secretly began the withdrawal of troops from Vietnam early in 1969. As the only full-strength division remaining in Vietnam in early 1970, the 101st Airborne Division was ordered to conduct the planned offensive Operation Texas Star near the A Shau Valley.
On March 12, 1970, the 3rd Brigade, 101st under the command of Major General Ben Harrison, began rebuilding abandoned Fire Support Base Ripcord which relied, as with most remote bases at the time, on a helicopter lifeline to get supplies in and the personnel out. The firebase was to be used for a planned offensive by the 101st to destroy NVA supply bases in the mountains overlooking the valley. Located on the eastern edge of the valley, and taking place at the same time as the Cambodian Incursion, the operation was considered covert.
As the 101st Airborne Division planned the attack on enemy supply bases, the North Vietnamese Army (NVA) was secretly observing their activities. From March 12 until June 30, the NVA was sporadically attacking the firebase. On April 29, President Nixon launched the Cambodian Incursion which was officially concluded on June 30 when the last American troops left Cambodia. Immediately after this, the United States made one final attempt to block the Ho Chi Minh Trail. After weeks of reconnaissance by the NVA, on the morning of July 1, 1970 the North Vietnamese Army launched a mortar attack on the firebase. During the 23-day siege, 75 US servicemen were killed, including Colonel Andre Lucas, who was posthumously awarded the Medal of Honor; and First Lt. Bob Kalsu, the only contemporaneously active pro athlete to be killed during the war.
Fighting from four hilltops, surrounded, and outnumbered nearly ten to one, U.S. forces caused heavy losses on eight enemy battalions, before an aerial withdrawal under heavy mortar, anti-aircraft, and small arms fire. After the U.S. Army withdrew from the firebase, USAF B-52 heavy bombers were sent in to carpet bomb the area. Major General (ret) Ben Harrison, then the commander of the 3rd Brigade of the 101st Airborne at FSB Ripcord, is of the opinion that perhaps the NVA losses at Ripcord, just as their losses of their major offensives of the Ia Drang in 1965 and Tet in 1968, crippled the offensive capability of NVA for two full years, resulting in the delaying of their Easter Offensive from 1971 to 1972.
