While Henry was in England, his brother Thomas, Duke of Clarence, led the English forces in France. On 22 March 1421, Thomas led the English to a disastrous defeat at the Battle of Baugé against a Franco-Scottish army. The duke was killed in the battle. On 10 June, Henry sailed back to France to retrieve the situation. It was to be his last military campaign. From July to August, Henry's forces besieged and captured Dreux, thus relieving allied forces at Chartres. On 6 October, his forces laid siege to Meaux, capturing it on 11 May 1422.
