In Florence cathedral hangs a remarkable portrait by Uccello of Sir John Hawkwood, the English soldier of fortune who commanded the Florentine army at the age of 70 and earned a formidable reputation as one of the foremost mercenaries of the late middle ages. His life is an amazing story. He rose from modest beginnings in an Essex village, fought through the French campaigns of Edward III, went to Italy when he was 40 and played a leading role in ceaseless strife of the city-states that dominated that country. His success over so many years in such a brutal and uncertain age was founded on his exceptional skill as a soldier and commander, and it is this side of his career that Stephen Cooper explores in this perceptive and highly readable study.
