, South Georgia
Conqueror was first on the scene, arriving off South Georgia on 18 April and carrying out a survey of key areas of the coast. She then withdrew to the northwest of the island to guard against any potential threats from the
Argentine navy. For the British, the first order of business was to carry out reconnaissance of Argentinian positions, whose forces and dispositions were unknown, though there was no evidence to suggest they had been reinforced since the initial occupation of the island on 3 April. The plan called for insertion of three SBS patrols at
Hound Bay, who would then travel by land and Gemini inflatable boat across
Cumberland East Bay and set up an
observation post at Brown Mountain overlooking Grytviken. The SAS plan was more ambitious, and called for a helicopter insertion of Mountain Troop, D squadron, on
Fortuna Glacier, 8 miles west of
Stromness. From there the unit would travel across the glacier, and reconnoitre
Leith,
Husvik, Stromness and East Fortuna bay. The SAS chose Fortuna glacier as the point of entry as it was sufficiently far from expected enemy positions so as to preclude detection, and the Argentines would not expect an attack from that direction. This choice was opposed by officers who had knowledge of local conditions, such as Captain
Nick Barker of
Endurance and members of the
British Antarctic Survey (BAS), who felt that the difficulties of travelling on the glacier were being underestimated. However, Major
Cedric Delves,
officer commanding D squadron, overruled their objections, and as the SAS had strong political backing within the British government, the plan was eventually put into action. On 20 April, an
RAF Victor based on Ascension carried out a radar reconnaissance of 150,000 square miles of South Atlantic, including South Georgia, remaining in flight for 14 hours and 45 minutes. On the same day, the Task Force arrived at its destination, and
Endurance moved into
Saint Andrews Bay to make contact with isolated BAS field parties. On the next day, the 15 men of Mountain troop, led by Captain
Gavin Hamilton, were airlifted onto Fortuna glacier by two
Wessex helicopters. They were immediately confronted with extreme conditions including 100
mph winds and freezing temperatures. Deep
crevasses slowed the advance, and when the men attempted to set up camp and wait out the storm, their tents were swept away by the wind. Finally, after 15 hours on the glacier, Captain Hamilton requested evacuation, with the message "Unable to move. Environmental casualties imminent." Three Wessex helicopters were dispatched from the Task Force: two Wessex Mk5s from
Tidespring and one Mk3 from
Antrim. After one failed attempt, they managed to locate and embark the stranded SAS men, but in
whiteout conditions, one pilot became disorientated and his aircraft crashed. The passengers were loaded onto the two remaining helicopters, but soon afterwards one of these hit a ridge and crashed, though once again without fatalities but resulting in a number of injured. The last Wessex,
Antrim′s Mk3, after having offloaded its troops on board the destroyer returned to the glacier and after two failed attempts managed to retrieve the downed SAS and aircrew, though their equipment had to be abandoned. The pilot, Lieutenant Commander Ian Stanley, managed to nurse his overloaded aircraft back to
Antrim and make an
emergency landing on her flight deck, for which he was later awarded the
Distinguished Service Order. Meanwhile, the SBS insertion fared little better. On 22 April, four men of 2 SBS were landed from
Endurance by
Wasp helicopter at Hound Bay, where the local BAS team informed them that no Argentines were in the area. On the next day, an attempt to insert reinforcements by helicopter was foiled by strong winds, and
Endurance had to approach within 800 yards of the coast in order to land the remaining SBS in Gemini inflatable boats. After having spent a night at
Dartmouth Point, the troop moved on foot through
Sörling Valley to the foot of
Nordenskjöld Glacier. Here a Wasp helicopter airlifted in two Geminis, but one was found to have been damaged during transport. The remaining boat was used to ferry half of the unit across Cumberland Bay East, but the crossing was thwarted by strong headwinds and accumulating
drift ice from the nearby glacier. With the weather deteriorating, the mission was called off, but the SBS had to wait another day to be evacuated. On 22 April, Young's Task Force was joined by the tanker
RFA Brambleleaf, which had travelled past the
Cape of Good Hope and originally arrived in the TEZ on 19 April, meeting HMS Endurance, before leaving again to wait to rendezvous with the other ships in the Task Force. The tanker had suffered heavy damage in a severe storm, and it was decided to transfer as much fuel as possible onto
Tidespring, under cover of
Plymouth, before she could begin her journey back to the UK for repairs. The long process began on the same day, but was momentarily interrupted when the three ships were spotted by an Argentine
C-130 flying a
maritime reconnaissance mission. The fuel transfer from
Brambleleaf to
Tidespring ended prematurely due to the suspected presence of Argentine submarine
Santa Fe in the area. Despite earlier setbacks, Young remained committed to completing his intelligence-gathering mission, and on the night of 22/23 April
Antrim entered
Stromness Bay in order to insert another SAS force. This time, Boat Troop, D squadron, led by Captain Tim Burls, were to be inserted in five Gemini boats. The attempt almost ended in disaster when two boats' engines refused to start and they were swept out to sea by an unexpected gale. One boat was rescued the following morning by
Antrims Wessex, while the other managed to restart their engine and reach the shore on the
Busen Peninsula. After towing another boat to shore,
Tommy Turtle went back to search for the others. The three remaining Geminis reached their intended objective on
Grass Island, where an
observation post was set up, after the men of 17 Troop had scaled a cliff in freezing conditions. They reported no Argentine activity in the Stromness area and signalled an SOS to
HMS Endurance, which the next day was able to airlift them out by her
Westland Wasp. After this operation, 17 Troop took to calling itself "The South Georgia Boating Club". ==Attack on
