Henry V died on 31 August 1422, at the Château de Vincennes. He had been weakened by dysentery, contracted during the siege of Meaux, and had to be carried in a litter towards the end of his journey. A possible contributory factor is heatstroke; the last day he was active he had been riding in full armour in blistering heat. He was 35 years old and had reigned for nine years. Shortly before his death, Henry V named his brother, John, Duke of Bedford, regent of France in the name of his son, Henry VI of England, then only a few months old. Henry V did not live to be crowned King of France himself, as he might confidently have expected after the Treaty of Troyes, because Charles VI, to whom he had been named heir, survived him by two months.
