After the conquest of the South Pole by Amundsen who by a narrow margin of days only was in advance of the British Expedition under Scott there remained but one great main object of Antarctic journeyings the crossing of the South Polar continent from sea to sea. When I returned from the Nimrod Expedition on which we had to turn back from our attempt to plant the British flag on the South Pole being beaten by stress of circumstances within ninety seven miles of our goal my mind turned to the crossing of the continent for I was morally certain that either Amundsen or Scott would reach the Pole on our own route or a parallel one. After hearing of the Norwegian success I began to make preparations to start a last great journey so that the first crossing of the last continent should be achieved by a British Expedition. We failed in this object but the story of our attempt is the subject for the following pages and I think that though failure in the actual accomplishment must be recorded there are chapters in this book of high adventure strenuous days lonely nights unique experiences and above all records of unflinching determination supreme loyalty and generous self sacrifice on the part of my men which even in these days that have witnessed the sacrifices of nations and regardlessness of self on the part of individuals still will be of interest to readers who now turn gladly from the red horror of war and the strain of the last five years to read perhaps with more understanding minds the tale of the White Warfare of the South. The struggles the disappointments and the endurance of this small party of Britishers hidden away for nearly two years in the fastnesses of the Polar ice striving to carry out the ordained task and ignorant of the crises through which the world was passing make a story which is unique in the history of Antarctic exploration.
