During the War of Devolution in 1667 Turenne captured the Spanish Netherlands practically without resistance. In 1672 the French invaded the Dutch Republic and the Marshal General conquered the country up to Amsterdam. Checked by the Dutch flooding of the land, he invaded the Holy Roman Empire the next year, reaching the Elbe and compelling Brandenburg to abandon the anti-French coalition. Faced with the loss of Alsace to superior Allied forces, he crowned his career with a series of battlefield victories, most notably at Turckheim (1675) and a masterful strategic turning movement around the Vosges in mid-winter that drove the Imperials from Alsace. He was killed by an Imperial cannonball at the battle of Salzbach in 1675.
