Aglncourt, now Azincourt, a village in the department of Pas de Calais, France, 7 m. N. E. of Hesdin, on the plains near which, on Oct. 25, 1415, Henry V. of England, with only 15,000 men, defeated the French army of more than 50,000, sent against him by the dauphin (son of the insane king, Charles VI.) and commanded by D'Albret, constable of France, aided by many famous captains. The battle, which lasted three or four hours, was won chiefly through the superiority of the English archers, who almost annihilated the cavalry of the enemy when these had been drawn, by the excellent strategy of the English, into a swamp that lay between the armies. In this desperate conflict the French lost the dukes of Alen-con, Brabant, and Barre, the high constable, grand master, and high admiral of France, the master of the crossbows, above 120 princes of the blood and nobles, and 8,400 belted knights, esquires, and gentlemen of birth; of the lower ranks there fell only 1,600 men. Of the English, there fell only the duke of York, the earl of Suffolk, one knight, one esquire, and about 600 men of all ranks and arms.

The dukes of Orleans and Bourbon and the high marshal of France, with 1,500 knights and nobles, were captured, and languished for many years in English prisons.
