He defeated Spanish armies at Arras and Dunkirk, overran much of the Spanish Netherlands in the War of Devolution, and in 1672 invaded the Dutch Republic before turning against the Holy Roman Empire. He was killed by a cannonball at the battle of Salzbach in 1675 and is ranked among history's great commanders.
