In the course of the Hundred Years War, Henry V was the English figure most responsible for the mutual antipathy that existed between France and England. His art of attacking an opponent by making total war on civilians, as well as soldiers, created tremendous distrust and enmity between the two countries, which survives even to this day. He was a man of many contradictions, a perverse mix of rigorous orthodoxy–exemplified by his fanatical and intolerant religion–and of neurotic insecurity, stemming in part from the dubious nature of his claim to the English throne.

Utilizing new discoveries from local French historical societies, Desmond Seward draws a portrait of Henry V that shows him as a brilliant military strategist, ambitious conqueror, and, at least briefly, triumphant warrior king.
