Shackelton's heroes

'Shackleton's Heroes' is a genuine treasure of Antarctic history, and an almost unbelievable tale of real heroes who risked themselves for the lives of others. It tells the extraordinary story of how a small party of men, against almost insurmountable obstacles, put down vital food depots on the Great Ice Barrier for Sir Ernest Shackleton's 1914-1917 Imperial Trans-Antarctic Expedition.
