In July 1907, Ernest Shackleton mounted the
British Antarctic Expedition, an attempt to reach the South Pole. The expedition provisioned its ship, the
Nimrod, at Lyttelton, near Christchurch in New Zealand, in late November and into December. There was much interest in New Zealand in the expedition, and it received several donations including from Buckley, who contributed £500. According to a letter written by Shackleton to his wife Emily, Buckley had promised a further £1000 if the expedition reached the South Pole. Buckley managed to join the expedition, securing passage aboard merely two hours prior through a personal appeal to Shackleton to be transported as far as the
pack ice. Rushing to gather his effects in time, he boarded the
Nimrod shortly before it departed Lyttelton for Antarctica on 1 January 1908. "Surely a record in the way of joining a Polar expedition", Shackleton is reported to have said at the time. To conserve its fuel for exploring the Antarctic,
Nimrod was towed south by the
Koonya as far as the pack ice, which it reached on 14 January. During his two-week service on
Nimrod, Buckley helped care for the expedition's horses and dogs. While the crew of the
Koonya slaughtered ten sheep on deck and sent the carcasses to the
Nimrod as fresh meat for their further journey, the sailors of the
Nimrod gave Buckley a champagne toast before transferring him to a whaleboat and onto the
Koonya for return to New Zealand. Buckley moved to the United Kingdom soon afterwards, living near Crawley, in the English county of Sussex. He remained friendly with Shackleton, and it was while visiting Buckley at his home that Shackleton took ill with heart problems. Shackleton refused to seek medical care and Buckley had to send him home in his own vehicle. ==First World War==
