been evacuated. Some cars had to be broken into to be moved. Chemical lights were placed in the HLZ in a NATO "Y" pattern. The entire mission would be conducted with night vision goggles, which required all lights in the embassy compound to be turned off. Main evacuation The main evacuation occurred in the early morning hours of 6 January and consisted of four waves of five CH-46 helicopters. The timing of this phase was determined by the range of the CH-46 Sea Knight, which lack aerial refueling capability; the ships were about away during this phase. An AC-130 was sent from Saudi Arabia to provide gunfire support during the evacuation and two UH-1 Iroquois helicopters were on standby to provide gunfire support, but were not deployed. The first wave departed Guam at 23:43. As the second wave landed, Major Siad arrived at the embassy gate accompanied by two truckloads of soldiers and held a grenade in one hand and a radio in the other. His request to speak with the ambassador was granted. Major Siad demanded that the evacuation cease immediately because the Somali government had not granted the US permission to carry out such a military operation. He claimed that he would radio soldiers to shoot down the helicopters if the operation continued. The second and third waves were able to depart without incident as the ambassador negotiated with the Major, who finally agreed to settle the matter for several thousand dollars in cash and keys to the ambassador's armored car. Ambassador Bishop remained engaged in conversation with the Major until he reached the helicopter landing zone to depart with the final wave to prevent the Major from reneging on the deal. The final wave departed the embassy at 1:49 and landed on Guam at 2:23; twenty minutes later, Ambassador Bishop declared the evacuation complete. Aftermath at the embassy Armed looters were observed entering the embassy compound as the final wave departed. The doors of the chancery—the main building of the embassy—were reportedly blown open by RPGs within two hours of the embassy's evacuation. Somali employees of the embassy—known as foreign service nationals (FSNs)—could not be evacuated. Ambassador Bishop tried unsuccessfully to have these employees airlifted to safer parts of Somalia. Many of the FSNs had sought refuge in the embassy with their families and about 30 were hired as guards and protected the embassy throughout the ordeal.
