The village of Agincourt in northern France was the scene of the defeat of a large French force by an English army led by Henry V. Henry’s force invaded Normandy in 1415, captured Harfleur, but was intercepted by a large French army after a long march north towards Calais. The English troops, mainly archers and foot soldiers, dug in behind wooden stakes between thickly wooded ground. The next day the French cavalry advanced on a narrow front across muddy ground only to be killed by English archers and infantry. A dozen French notables, including the Constable of France, died, together with perhaps 1,500 knights and 4,500 men‐at‐arms. English casualties were light but included the Duke of York and the Earl of Suffolk. The battle was fought on St Crispin’s day.
