it. A Dracone Barge was moored offshore, and piping attached that allowed aviation fuel to be pumped into collapsible tanks ashore. This allowed helicopters to refuel ashore, eliminating the need to land on the LPDs, which had two helipads, or the LSLs, which had one each, for refuelling, for which they competed with the 15 light helicopters of 3 Commando Brigade Air Squadron. On 24 May, 11 Field Squadron commenced work on an airstrip to allow Harriers to refuel as well. The plant and equipment earmarked for this was lost on Atlantic Conveyor, but Stromness had aluminium panels for airfield surfacing, which were landed at Green Beach by helicopter and landing craft, and taken to the site with civilian vehicles. The airstrip was completed, with a ski jump for Harriers, assembled by hand, on 2 June. The absence of 383 Commando Petroleum Troop, though, meant that there was no one to operate the fuel points until the 5th Infantry Brigade arrived. Its attached 91 Ordnance Company had a petroleum platoon, the only regular army one based in the UK. These specialists took over the EFHE at Port San Carlos as soon as they arrived on 3 June, allowing Harriers to be refuelled there from 5 June. It was damaged by a Harrier that crash landed on 8 June, but was repaired. Over 150 operational sorties were flown from the airstrip between 5 and 14 June. Argentine air attacks were initially directed at the ships, but on 27 May four Douglas A-4 Skyhawks attacked the BMA, dropping twelve bombs, only four of which exploded. Six men were killed and thirty wounded. The field hospital was struck by two bombs, neither of which exploded. They would remain in place, sandbagged and defuzed, for the rest of the campaign. Bombs that struck the ordnance area set off stockpiles of 105 mm artillery shells, MILAN missiles and 81 mm mortar bombs. The Commando Logistic Regiment had no fire fighting equipment, so the fire was left to burn itself out, and explosions continued through the night. All of 45 Commando's MILAN missiles were lost, along with two hundred mortar bombs and three hundred artillery rounds. The Battle of Goose Green on 28 and 29 May confirmed what logisticians had suspected and feared; the expenditure of ammunition was not only five times greater than that expected in a limited war, it exceeded that forecast for an
