Philip's insistence Condé be restored to his French titles and lands. Since Philip viewed this as a personal obligation, the war continued. France had previously relied on the Dutch to provide naval support against Spain, which ended after Westphalia; in 1657, Mazarin replaced this loss by negotiating an anti-Spanish alliance with the English Commonwealth. This expanded the scope of the Anglo-Spanish War (1654–1660), while France withdrew support for the exiled Charles II of England, whose supporters joined the Spanish as a result. After the Anglo-French capture of Dunkirk in June 1658, Philip requested a truce, which Mazarin refused, but once again success proved illusory. On 15 August, Spain won an important victory at Camprodon in Catalonia, Cromwell's death in September led to political chaos in England, while fighting in northern Italy ended when French allies Savoy and Modena agreed to a truce with Spanish commander Caracena. Treaty of the Pyrenees and marriage contract On 8 May 1659, France and Spain began negotiating terms; the death of Oliver Cromwell in September 1658 weakened England, which was allowed to observe but excluded from the talks. Although the Anglo-Spanish War was suspended after the 1660 restoration of Charles II, it did not formally end until the 1667 Treaty of Madrid. Under the Treaty of the Pyrenees, signed on 5 November 1659, France gained Artois and Hainaut along its border with the Spanish Netherlands, as well as Roussillon. These were more significant than often assumed; in combination with the 1648 Treaty of Münster, France strengthened its borders in the east and south-west, while in 1662, Charles II sold Dunkirk to France. Acquisition of Roussillon established the Franco-Spanish border along the Pyrenees, but divided the historic Principality of Catalonia, an event still commemorated each year by French Catalan-speakers in Perpignan. In addition to these territorial loses, Spain was forced to recognize and confirm all of the French territorial gains at the Peace of Westphalia. France withdrew support from Afonso VI of Portugal, while Louis XIV renounced his claim to be Count of Barcelona, and king of Catalonia. Condé regained his possessions and titles, as did many of his followers, such as the Comte de Montal, but his political power was broken, and he did not hold military command again until 1667. An integral part of the peace negotiations was the marriage contract between Louis and Maria Theresa, which he used to justify the 1666 to
