(June 14, 1658), military victory of French and English forces led by Henri de La Tour d'Auvergne, Viscount de Turenne, attacking Spanish forces near Dunkirk (then in the Spanish Netherlands). The victory contributed greatly to the surrender of Dunkirk by Spain and to the conclusion of the Peace of the Pyrenees by France and Spain (1659).

The battle occurred after Oliver Cromwell sent General William Lockhart with 6,000 English infantry to reinforce Turenne, who was besieging Dunkirk. A Spanish force, under Don Juan the Younger of Austria and Louis II de Bourbon, 4th Prince de Condé, with several corps of English royalists commanded by the Duke of York (later James II), arrived to relieve Dunkirk and took up positions on the dunes. Turenne attacked. Although Condé's cavalry gained an advantage, the rest of the Spanish force could not resist the Anglo-French troops and retreated, except for a corps of English royalists (who later rejoined their king, Charles II, at Ypres).
