The Battle of Cr矇cy was an English victory during the Edwardian phase of the Hundred Years' War. The battle was fought on August 26, 1346 near Cr矇cy, in northern France. An army of English, Welsh, and allied mercenary troops led by Edward III of England, engaged and defeated a much larger army of French, Genoese and Majorcan troops led by Philip VI of France. Emboldened by the lessons of tactical flexibility and utilisation of terrain learned from the earlier Saxons, Vikings, Muslims and the recent battles with the Scots, the English army won an important victory. The battle heralded the rise of the longbow as the dominant weapon on the Western European battlefield, and helped to continue the rise of the infantryman in medieval warfare. The heavy casualties incurred by the French knightly class at the hands of peasants wielding ranged weapons was indicative of the decline of chivalry, and the emergence of a more practical, pragmatic approach to conducting warfare. The battle crippled the French army's ability to come to the aid of Calais, which fell to the English the following year. Calais would remain under English rule for over two centuries, falling in 1558.
