Navigation became, in Worsley’s words, “a merry jest of guesswork”, as they encountered the worst of the weather. The James Caird was taking on water in heavy seas and in danger of sinking, kept afloat by continuous bailing. The temperature fell sharply, and a new danger presented itself in the accumulations of frozen spray, which threatened to capsize the boat. In turns, they had to crawl out on to the pitching deck with an axe and chip away the ice from deck and rigging. For 48 hours they were stopped, held by a sea anchor, until the wind dropped sufficiently for them to raise sail and proceed. Despite their travails, Worsley’s third observation, on 4 May, put them only 250 nautical miles (460 km; 290 mi) from South Georgia.
On 5 May the worst of the weather returned, and brought them close to disaster in the largest seas so far. Shackleton later wrote: “We felt our boat lifted and flung forward like a cork in breaking surf”. The crew bailed frantically to keep afloat. Nevertheless, they were still moving towards their goal, and a dead reckoning calculation by Worsley on the next day, 6 May, suggested that they were now 115 nautical miles (213 km; 132 mi) from the western point of South Georgia. The strains of the past two weeks were by now taking their toll on the men. Shackleton observed that Vincent had collapsed and ceased to be an active member of the crew, McCarthy was “weak, but happy”, McNish was weakening but still showing “grit and spirit”.
On 7 May Worsley advised Shackleton that he could not be sure of their position within ten miles. To avoid the possibility of being swept past the island by the fierce south-westerly winds, Shackleton ordered a slight change of course so that the James Caird would reach land on the uninhabited south-west coast. They would then try to work the boat round to the whaling stations on the northern side of the island. “Things were bad for us in those days”, wrote Shackleton. “The bright moments were those when we each received our one mug of hot milk during the long, bitter watches of the night”. Late on the same day floating seaweed was spotted, and the next morning there were birds, including cormorants which were known never to venture far from land. Shortly after noon on 8 May came the first sighting of South Georgia.
As they approached the high cliffs of the coastline, heavy seas made immediate landing impossible. For more than 24 hours they were forced to stand clear, as the wind shifted to the north-west and quickly developed into “one of the worst hurricanes any of us had ever experienced”. For much of this time they were in danger of being driven on to the rocky South Georgia shore, or of being wrecked on the equally menacing Annenkov Island, five miles from the coast. On 10 May, when the storm had eased slightly, Shackleton was concerned that the weaker members of his crew would not last another day, and decided that whatever the hazard they must attempt a landing. They headed for Cave Cove near the entrance to King Haakon Bay, and finally, after several attempts, made their landing there. Shackleton was later to describe the boat journey as “one of supreme strife”; historian Caroline Alexander comments: “They could hardly have known—or cared—that in the carefully weighted judgement of authorities yet to come, the voyage of the James Caird would be ranked as one of the greatest boat journeys ever accomplished”.
