On June 14th 1658, during the battle of the Dunes, a decisive engagement fought near Dunkirk, the Viscount of Turenne commanded its French troops but also 4 English infantry batallions from Cromwell's troops. It was a military victory of French and English forces attacking Spanish forces near Dunkirk (then in the Spanish Netherlands). The victory led to the surrender of Dunkirk by Spain and to the conclusion of the Peace of the Pyrenees by France and Spain (1659). English and Portuguese forces then defeated Spain at Montes Claros and Villa Viciosa, ensuring Portuguese independence (1665).
On the French side (Turenne) : about 15000 men
- 57 French cavalry squadrons
- 19 Infantry batallions (with 4 English infantry batallions and 2 swiss guards batallions)
- musketeers detachments
- 5 artillery pieces
losses : 500 men
On the Spanish side (Don John of Austria ) : about 14000 men
- 62 Spanish cavalry squadrons
- 13.5 Infantry battalions (with 3 English royalist batallions, 2 Irish batallions, 3 Walloon batallions)
losses : 6000 men (3000 to 4000 POW)
The Peace of the Pyrenees ended the war between France and Spain that, continuing after the Peace of Westphalia (end of the Thirty years war), had been complicated by French intervention in the revolt of the Catalans (1640-52) and by Spanish intervention in the Fronde. Together with the Peace of Westphalia, it marked the rise of France as the dominant European power. France received Roussillon and extensive territories in Flanders, while its Spanish border was set at the Pyrenees. A marriage contract between Louis XIV and Marie Thérèse, daughter of Philip IV of Spain, was included in the terms. The infanta renounced her claims to the Spanish throne in consideration of a large payment. The nonpayment of that dowry was the occasion for the War of Devolution and, indirectly, the War of the Spanish succession.
