could separate the men, they soon abandoned this plan: the men pitched camp and decided to wait. They hoped that the clockwise drift of the pack would carry them to Paulet Island where they knew there was a hut with emergency supplies. But the pack ice held firm as it carried the men well past Paulet Island, and did not break up until 9 April. The crew then had to sail and row the three ill-equipped lifeboats through the pack ice to Elephant Island, a trip which lasted five days. Crean and Hubert Hudson, the navigating officer of the Endurance, piloted their lifeboat with Crean effectively in charge as Hudson appeared to have suffered a breakdown. Upon reaching Elephant Island, Crean was one of the "four fittest men" detailed by Shackleton to find a safe camping-ground. Shackleton decided that, rather than waiting for a rescue ship that would probably never arrive, one of the lifeboats should be strengthened so that a crew could sail it to South Georgia and arrange a rescue. After the party was settled on a penguin rookery above the high-water mark, a group of men led by ship's carpenter Harry McNish began modifying one of the lifeboats—the James Caird—in preparation for this journey, which Shackleton would lead. Frank Wild, who would be in command of the party remaining on Elephant Island, wanted the dependable Crean to stay with him; Shackleton initially agreed, but changed his mind after Crean begged to be included in the boat's crew of six. The boat journey to South Georgia, described by polar historian Caroline Alexander as one of the most extraordinary feats of seamanship and navigation in recorded history, took 17 days through gales and snow squalls, in seas which the navigator, Frank Worsley, described as a "mountainous westerly swell". After setting off on 24 April 1916 with just the barest navigational equipment, they reached South Georgia on 10 May 1916. Shackleton, in his later account of the journey, recalled Crean's tuneless singing at the tiller: "He always sang when he was steering, and nobody ever discovered what the song was ... but somehow it was cheerful". The party made its South Georgia landfall on the uninhabited southern coast, having decided that the risk of aiming directly for the whaling stations on the north side was too great; if they missed the island to the north they would be swept out
