On reaching Port Stanley, Shackleton informed London by cable of his whereabouts and requested that a suitable vessel be sent south for the rescue operation. He was informed by the Admiralty that nothing was available before October, which in his view was too late. Then, with the help of the British Minister in Montevideo, Shackleton obtained from the Uruguayan government the loan of a tough trawler, "Instituto de Pesca No. 1", which started south on 10 June. Again the pack thwarted them. In search of another ship, Shackleton, Worsley and Crean travelled to Punta Arenas, where they met Allan MacDonald, the British owner of the schooner "Emma". McDonald equipped this vessel for a further rescue attempt, which left on 12 July, but with the same negative result—the pack defeated them yet again. Shackleton later named a glacier after McDonald on the Brunt Ice Shelf in the Weddell Sea. After problems arose in identifying this glacier, a nearby ice rise was renamed the McDonald Ice Rumples.
