1658 featured an Anglo-French offensive in North Flanders, the main objective being Dunkirk, a centre for Spanish privateer attacks on English shipping. After the loss of Dunkirk in June, Spain requested a truce, which Mazarin initially refused. The last major battle was a Spanish victory at Camprodon, Catalonia, on the 15 August 1658. Cromwell's death in September led to political chaos in England, while French allies Savoy and Modena ended the war in Northern Italy by agreeing a truce with the Spanish commander, Caracena.
