Henry V (of England)

King of England from 1413, son of Henry IV. Invading Normandy in 1415 (during the Hundred Years' War), he captured Harfleur and defeated the French at Agincourt. He invaded again in 1417–19, capturing Rouen. His military victory forced the French into the Treaty of Troyes in 1420, which gave Henry control of the French government. He married Catherine of Valois in 1420 and gained recognition as heir to the French throne by his father-in-law Charles VI, but died before him. He was succeeded by his son Henry VI.

Henry was knighted at the age of 12 by Richard II on his Irish expedition of 1399, and experienced war early. He was wounded in the face by an arrow while fighting against his military tutor Harry ‘Hotspur’ at Shrewsbury. Campaigns in Wales against Owen Glendower taught him the realities of siege warfare. He was succeeded by his son Henry VI.
