On 21 Oct 1345 Henry of Grosmont 1st Duke Lancaster (age 35) commanded an English army including Walter Manny 1st Baron Manny (age 35) at Auberoche, Perigueux during the Battle of Auberoche. The battle was a significant victory for the English with the French forces being heavily defeated. The ransoms alone made a fortune for many of the soldiers in Derby's army, as well as Derby himself, who was said to have made at least £50,000 from the day's captives, and sealed his reputation as 'one of the best warriors in the world'.
