Henri de la Tour d'Auvergne, Vicomte de Turenne in the context of "Marshal of France"

Line infantry was the type of infantry that formed the bulk of most European land armies from the mid-17th century to the mid-19th century. Maurice of Nassau and Gustavus Adolphus are generally regarded as its pioneers, while Turenne and Montecuccoli are closely associated with the post-1648 development of linear infantry tactics. For both battle and parade drill, it consisted of two to four ranks of foot soldiers drawn up side by side in rigid alignment, and thereby maximizing the effect of their firepower. By extension, the term came to be applied to the regular regiments "of the line" as opposed to light infantry, skirmishers, militia, support personnel, plus some other special categories of infantry not focused on heavy front line combat.

The Battle of the Dunes (French: Bataille des Dunes, Spanish: Batalla de las Dunas), also known as the Battle of Dunkirk, took place on 14 June 1658, near the strategic port of Dunkirk in what was then the Spanish Netherlands. Part of the Franco-Spanish War and concurrent Anglo-Spanish War, a French army under Turenne, supported by troops from the Commonwealth of England, had besieged Dunkirk. Led by John Joseph of Austria and Louis, Grand Condé, a Spanish force supported by the Royalist Army in Exile and French Fronde rebels attempted to raise the siege but suffered a severe defeat.

Despite this victory, both the French and Spanish were financially exhausted by the long running war and negotiated the Treaty of the Pyrenees in November 1659. England retained possession of Dunkirk until 1662 when the port was sold to France by Charles II.

The Battle of Zusmarshausen was fought on 17 May 1648 between Bavarian-Imperial forces under von Holzappel and an allied Franco-Swedish army under the command of Carl Gustaf Wrangel and Turenne in the modern Augsburg district of Bavaria, Germany. The allied force emerged victorious, and the Imperial army was only rescued from annihilation by the stubborn rearguard fighting of Raimondo Montecuccoli and his cavalry.

Zusmarshausen was the last major battle of the war to be fought on German soil during the Thirty Years' War, and was also the largest battle (in terms of numbers of men involved; casualties were relatively light) to take place in the final three years of the war.
