Please answer the following question: Given the following context:  The end of Patience Camp was signalled on the evening of 8 April, when the floe suddenly split. The camp now found itself on a small triangular raft of ice; a break-up of this would mean disaster, so Shackleton readied the lifeboats for the party's enforced departure. He had now decided they would try, if possible, to reach the distant Deception Island because a small wooden church had been reportedly erected for the benefit of whalers. This could provide a source of timber that might enable them to construct a seaworthy boat.At 1 p.m. on 9 April, the Dudley Docker was launched, and an hour later all three boats were away. Shackleton himself commanded the James Caird, Worsley the Dudley Docker, and navigating officer Hubert Hudson was nominally in charge of the Stancomb Wills, though because of his precarious mental state the effective commander was Tom Crean.The boats were surrounded by ice, dependent upon leads of water opening up, and progress was perilous and erratic. Frequently the boats were tied to floes, or dragged up onto them, while the men camped and waited for conditions to improve. Shackleton was wavering again between several potential destinations, and on 12 April, rejected the various island options and decided on Hope Bay, at the very tip of Graham Land. However, conditions in the boats, in temperatures sometimes as low as −20 °F (−29 °C), with little food and regular soakings in icy seawater, were wearing the men down, physically and mentally. Shackleton therefore decided that Elephant Island, the nearest of the possible refuges, was now the most practical option.On 14 April, the boats lay off the south-east coast of Elephant Island, but could not land as the shore consisted of perpendicular cliffs and glaciers. Next day the James Caird rounded the eastern point of the island, to reach the northern lee shore, and discovered a narrow shingle beach. Soon afterwards, the three boats, which had been separated during the previous night, were reunited at this landing place. It was apparent from...  answer the following question:  On April 12 what island did Shackleton decide to travel to?
A:
Elephant Island
