The helicopter's loss caused the British to suspect that Argentine forces were still operating in the area, so patrols were mounted by Gurkha soldiers.[9] When the Gurkhas came across the personnel manning the Pleasant Peak station there was potential for another friendly fire incident to occur.[17] At first light a proper search was carried out, and the Gazelle's wreckage was found along with the dead aircrew and passengers; 5th Infantry Brigade's first casualties of the war.[9][18] Immediately there were suspicions that Cardiff had been responsible for the shootdown, and later that evening Rear Admiral "Sandy" Woodward declared a "Weapons Tight" order, forbidding the engagement of any aircraft not positively identified as hostile, for all contacts detected flying over East Falkland at less than 200 kn (370 km/h) and under 610 m (2,000 ft).[2][7]
