Canada was led to war by a bigoted, ignorant, self-obsessed Minister of Militia, who may well have been clinically insane, but the importance of Canada's contribution in that war owes a great deal to him. The man of course, was Colonel - later made Lieutenant General by his own hand - Sam Hughes. Sam's Army is a compelling portrait of a complex man and the formidable military he built. Sam Hughes was not your standard-issue military leader. Canada's World War I Minister of Militia and Defence concentrated power in his own hands, insisted that the Canadian military use the ill-conceived Ross rifle and liberally promoted his cronies. But there was no denying Hughes was a visionary. He assembled the world's largest-ever volunteer army and bucked superiors to keep his ferocious fighting force together in one Canadian Corps.

Canadian military accomplishments in the last hundred days of World War I, when the German Army was destroyed, surpassed those of any other army. The Canadian success was, in no small measure, due to Arthur Currie, whom a recent British historian describes as "the most successful Allied General and one of the least well known."
