This consisted of six North Sea oil rig support barges that were linked together. Atop them were warehouses, refrigerated storages, and accommodation and mess facilities for 200 people. It could berth vessels up to long, and was connected to the shore by a two-lane causeway. An access road was constructed by 37 Engineer Regiment. With the end of hostilities in the Falklands (although Operation Keyhole, the reoccupation of Thule Island in the South Sandwich Islands, remained, and was concluded on 20 June), the British forces became responsible for feeding the civilian population and 11,848 Argentine prisoners. Due to the British blockade of the island, they had only three days' rations. The prisoners were initially issued with Argentine rations, but the British withheld the officer rations as they contained alcohol. Prisoners rioted on 16 June, setting fire to their clothing store. Those taken at Goose Green had already been repatriated to Argentina via Montevideo in neutral Uruguay on Norland. Some 5,000 Argentine prisoners were embarked on Canberra and 1,000 on Norland on 17 June. By 20 June 10,250 prisoners had been repatriated. Only 593 remained, including Menéndez. These were held for intelligence gathering, and to encourage Argentina to end hostilities. One British prisoner, Flight Lieutenant Jeffrey Glover, was held in Argentina; he was released on 16 July. The last Argentine prisoners were repatriated by 14 July. The Bakery Section of 91 Ordnance Company baked its first loaf in the Falkland Islands on 30 June. It baked up to 6,000 loaves per day before settling down to just 4,000 by August. Although rations could soon be supplemented with fresh fruit and vegetables, it was not until August that the troops could be fed fresh rations. A wing of the small King Edward VII Memorial Hospital at Port Stanley was occupied by 16 Field Ambulance. Its first task was sorting through captured Argentine medical supplies. The military hospital wing opened on 29 June. Uganda dropped anchor at Port William to supply backup care, and donated fifty hospital beds and bedding to King Edward VII Memorial Hospital. Having sailed from the UK on the TEV Rangatira on 19 June, 2 Field Hospital reached the Falkland Islands on 11 July. Its staff included fourteen officers and other ranks of Queen Alexandra's Royal Army Nursing Corps. Its tent accommodation had been lost on Atlantic Conveyor, so it moved into the King Edward VII Memorial Hospital. About
