The Naval Battle of Tarragona fought between 4 and 6 July 1641, was a naval engagement of the Reapers' War in which a Spanish galley fleet led by the Duke of Fernandina attempted to break the French naval blockade over Tarragona, at that time besieged by land by the French and Catalan armies under the French Viceroy of Catalonia. The French blockading fleet was under command of Henri d'Escoubleau de Sourdis, Archbishop of Bordeaux, and consisted both of sailing and rowing vessels. On 4 July it was engaged by the Spanish galleys, of which some managed to enter the port of the town during a fierce action. In the end, a large number of Spanish galleys were abandoned when their crews panicked and fled to the beaches. On the night of 6 July Abraham Duquesne escorted 5 fireships to the mole of the harbor, where the Spanish galleys were abandoned, and set fire to them.
