SYNOPSIS: LAM SON 719 was a large offensive operation against NVA
communications lines in Laos. The operation called for ARVN troops to drive
west from Khe Sanh, cut the Ho Chi Minh Trail, seize Tchpone and return to
Vietnam. The ARVN would provide and command the ground forces, while U.S.
Army and Air Force would furnish aviation airlift and supporting firepower.
The 101st Airborne Division commanded all U.S. Army aviation units in direct
support of the operation. Most of the first part of the operation, which
began January 30, 1971, was called Operation DEWEY CANYON II, and was
conducted by U.S. ground forces in Vietnam.

On February 8, 1971, early into the operation, a U.S. Army OH6A helicopter
was shot down about 8 miles east of Tchpone. This aircraft, flown by W1
Gregory Crandall, pilot, SP4 Robert J. Engen, scout/observer, and Sgt.
Walter E. Lewellen, crew chief, was conducting an aerial reconnaissance
mission when Crandall radioed that he was under heavy enemy fire. As he
maneuvered to evade the fire, the aircraft was seen to crash and catch on
fire. There was one major and six secondary explosions. About March 7, an
ARVN unit spotted the wreckage, but was unable to reach it to thoroughly
investigate. It was never learned for certain that the crew perished.

Losses were heavy in Lam Son 719. The ARVN lost almost 50% of their force.
U.S. aviation units lost 168 helicopters; another 618 were damaged.
Fifty-five aircrewmen were killed, 178 wounded, and 34 missing in action in
the entire operation, lasting until April 6, 1971.

In all, nearly 600 Americans were lost in Laos, but because we did not
negotiate with the Pathet Lao, no Americans held in Laos were released.
Since that time, over 10,000 reports have been received relating to
Americans prisoner, missing or unaccounted for in Southeast Asia. Although
many authorities are convinced that hundreds remain alive, the U.S. has not
secured the release of a single man.

SP4 ROBERT JOSEPH ENGEN

Return to Service Member Profiles

On October 30, 1991, the Central Identification Laboratory-Hawaii (CILHI, now DPAA) identified the remains of Specialist 4 Robert Joseph Engen, missing from the Vietnam War.

Specialist 4 Engen entered the U.S. Army from California and was a member of Troop C, 2nd Squadron, 17th Cavalry Regiment, 101st Airborne Division. On February 18, 1971, he was an observer aboard an OH-6A Cayuse (tail number 67-16528, call sign "Grip 11") on a visual reconnaissance mission over Savannakhet Province, Laos. During the mission, the aircraft came under heavy enemy fire, crashed, and exploded, killing SP4 Engen. The wreckage landed northwest of Ban Houay Kasan village in an area that remained under enemy control, which prevented efforts to recover SP4 Engen's remains at the time. However, in 1990, a joint U.S./Laotian investigative team traveled to the crash site and recovered aircraft wreckage, personal artifacts, and human remains, and in 1991, SP4 Engen was identified from these remains.

Specialist 4 Engen is memorialized in the Courts of the Missing at the National Memorial Cemetery of the Pacific.
