Blood of the innocents - Michael Jecks

The thrilling finale to the Vintener trilogy from the master of historical adventure.
France, 1356: Ten years have passed since the battle of Crecy, and the English fighters are still abroad, laying siege to cities, towns and even small villages. Meanwhile the Prince of Wales raids across France to draw King John into a battle for sovereignty.
Berenger Fripper, having lost everything to the plague, is now captain of a company of mercenaries, but treachery and deceit dog him when his travels with the company lead him to Uzerche. And then his path crosses that of Prince Edward and his men as they embark on their latest chevauche to bring death and disaster to the King of France's subjects.
Enlisted as Vintener under Sir John de Sully, Berenger finds himself drawn into a new struggle. Can the English defeat the much larger French army, or will they find themselves finally overcome when their weary feet bring them at last to the field of battle near Poitiers.
