"Endurance" sailed from Plymouth on 6 August 1914 and set course for Buenos Aires, Argentina, under Worsley's command. Shackleton remained in Britain, finalising the expedition's organization and attending to some last-minute fundraising. This was "Endurance"'s first major voyage following its completion and amounted to a shakedown voyage. The trip across the Atlantic took more than two months. Built for the ice, her hull was considered by many of her crew too rounded for the open ocean. Shackleton took a steamer to Buenos Aires and caught up with his expedition a few days after "Endurance"'s arrival.
