Henri de La Tour d'Auvergne, Viscount of Turenne

Henri de La Tour d'Auvergne, Vicomte de Turenne (1611–1675), was Marshal General of the King's camps and armies and is celebrated alongside Condé as the greatest military commander of 17th-century France. Learning the art of siegecraft in the Dutch Republic under his uncles Maurice and Frederick Henry of Nassau, Turenne became a French marshal at age thirty-two during the Thirty Years' War.

Turenne achieved renown during the Franco-Spanish War, winning the Battle of the Dunes in 1658 outside Dunkirk alongside Cromwell's English ironsides. His undisputed masterpiece was the Alsace Winter Campaign of 1674–1675: when an Imperial-German coalition army of 50,000 invaded Alsace, Turenne marched his 20,000 men behind the screen of the Vosges Mountains in midwinter snow, appearing unexpectedly behind the enemy at Turckheim and driving them across the Rhine without a general siege. Struck down by a stray cannonball at Sasbach in 1675, he was buried among kings in Saint-Denis.
