Operation Frequent Wind - The DAO Compound

The DAO Compound

At 14:06 two UH-1E Huey helicopters carrying General Carey and Colonel Gray (commander of Regimental Landing Team 4 (RLT4)) landed at the DAO compound. During their approach to the compound, they experienced a firsthand view of the PAVN's firepower as they shelled nearby Tan Son Nhut Airport with ground, rocket, and artillery fire. They quickly established an austere command post in preparation for the arrival of the Marine CH-53s and the ground security force.

The first wave of 12 CH-53s from HMH-462 loaded with the LT 2/4's command groups "Alpha" and "Bravo," and Company F and reinforced Company H arrived in the DAO compound at 15:06 and the Marines quickly moved to reinforce the perimeter defenses. As they approached the helicopters had taken rifle and M-79 grenade fire from ARVN troops but without causing any apparent damage. The second wave of 12 CH-53s from HMH-463 landed in the DAO compound at 15:15 bringing in the rest of the BLT. A third wave of two CH-53s from HMH-463 and eight USAF CH-53Cs and two USAF HH-53s of the 40th Aerospace Rescue and Recovery Squadron (all operating from the USS Midway) arrived shortly afterwards.

"Alpha" command group, two rifle companies, and the 81 mm mortar platoon were deployed around the DAO headquarters building (the Alamo) and its adjacent landing zones. Companies E and F respectively occupied the northern and southern sections between the DAO headquarters and the DAO Annex. "Bravo" command group, consisting of two rifle companies and the 106 mm recoilless rifle platoon, assumed responsibility for security of the DAO annex and its adjoining landing zones. Company G occupied the eastern section of the annex, while Company H assumed control of the western section.

The HMH-462 CH-53s loaded with evacuees and left the compound, they unloaded the first refugees delivered by Operation Frequent Wind at 15:40. At about 17:30 General Carey ordered the extraction of 3rd Platoon, Company C of BLT 1/9, which had been landed at the DAO compound on 25 April to assist the Marine Security Guard. Between 19:00 and 21:00 General Carey transferred 3 platoons (130 men) of BLT 2/4 into the embassy compound to provide additional security and assistance for the embassy.

At 19:30 General Carey directed that the remaining elements guarding the annex be withdrawn to DAO headquarters (the Alamo) where the last of the evacuees would await their flight. Once completed, the new defensive perimeter encompassed only LZ 36 and the Alamo. By 20:30 the last evacuees had been loaded onto helicopters. With the evacuation of the landing control teams from the annex and Alamo completed, General Carey ordered the withdrawal of the ground security forces from the DAO compound around 22:50. At 23:40 Marines destroyed the satellite terminal, the DAO compound's last means of direct communication with the outside world. At 00:30 on 30 April, thermite grenades, having been previously placed in selected buildings, ignited as two CH-53s left the DAO parking lot carrying the last elements of 2nd Battalion 4th Marines.
