Macklin, who conducted the postmortem, concluded that the cause of death was atheroma of the coronary arteries exacerbated by "overstrain during a period of debility". Leonard Hussey, a veteran of the Imperial Trans-Antarctic expedition, offered to accompany the body back to Britain; while he was in Montevideo en route to England, a message was received from Emily Shackleton asking that her husband be buried in South Georgia. Hussey returned to South Georgia with the body on the steamer , and on 5 March 1922, Shackleton was buried in the Grytviken cemetery, South Georgia, after a short service in the Lutheran church, with Edward Binnie officiating. Macklin wrote in his diary: "I think this is as 'the Boss' would have had it himself, standing lonely in an island far from civilisation, surrounded by stormy tempestuous seas, & in the vicinity of one of his greatest exploits."
