A Special Forces camp was established at Dong Xoai, a district capital in Phuoc Long Province, in late May 1965. Dong Xoai lay astride a Viet Cong supply route from Cambodia into War Zone D. At about 11 PM on the night of 9 June, the SVN forces around Dong Xoai were attacked by the 762nd and 763rd VC Regiments. Beginning about 11:30 PM the camp came under heavy mortar and ground attack and was overrun.

South Vietnamese and US advisory relief forces were alerted. The first to arrive was an advisory team airlifted from Tan Son Nhut air base near Saigon. The team was aboard a UH-1B helicopter (serial 63-08557) from the 118th Aviation Company. US personnel included

·              WO Donald R. Saegaert, 118th Avn Co, aircraft commander;
       LT Walter L. Hall, 118th Avn Co, pilot;
      SGT Craig L. Hagen, 118th Avn Co, gunner;
      SSGT Joseph J. Compa, 118th Avn Co, crew chief;
      CPT Bruce G. Johnson, Advisory Team 70;
      SFC Fred M. Owens, Advisory Team 70; and
      SSGT Robert L. Curlee, Advisory Team 70 (medic).

After the UH-1B landed it came under heavy mortar and small arms fire. The helicopter took off and started a climbing turn. It then went into uncontrolled flight and crashed, skidded into parked vehicles, and burst into flames.

Captain Johnson, an advisor to the South Vietnamese Army's 5th Infantry Division, reported to another helicopter in the area that the UH-1B's crew and all others on board were dead and his position was receiving incoming enemy mortar fire. There was no further transmission from Captain Johnson after the end of the mortar fire. A later search of the area failed to produce any sign of the seven servicemen. Villagers stated that the Viet Cong had carried away the bodies of 7 Americans and had buried them.

Although the other six men could be classed as Killed in Action based on Captain Johnson's verbal report, Johnson himself was carried as Missing in Action. On 27 Feb 1978, the Secretary of the Army issued a Presumptive Finding of Death for Bruce Johnson, who had been promoted to Lieutenant Colonel while in MIA status. As of 08 Feb 2008 the remains of the seven Americans have not been repatriated.

Sergeant Hagen's Letter of Condolences file at the LBJ Library contains the notation that he was on a temporary duty assignment as a door gunner with the 118th Avn Co; his permanent duty station was the 1st Battalion, 14th Infantry, 25th Infantry Division in Hawaii.

A total of 18 US servicemen died in the attack; the other eleven were
