Lieutenant-Admiral Michiel de Ruyter virtually controlled the seas around the south coast of England after a battle that took place in what year ?
Treaty of Breda (1667) The Treaty of Breda was signed at the Dutch city of Breda, 31 July (Gregorian calendar), 1667, by England, the United Provinces (Netherlands), France, and Denmark–Norway. It brought a hasty end to the Second Anglo-Dutch War (1665–1667) in favour of the Dutch, as Louis XIV's forces began invading the Spanish Netherlands as part of the War of Devolution, but left many territorial disputes unresolved. It was thus a typical quick "uti possidetis" treaty. In the latter stages of the war, the Dutch had prevailed. Lieutenant-Admiral Michiel de Ruyter virtually controlled the seas around the south coast of England, following his successful Raid on the Medway, and his presence encouraged English commissioners to sue for peace quickly. Negotiations, which had been long protracted, and had actually begun in Breda before the raid, took only ten days to conclude after resumption of talks.
Invasion of Martinique (1809) The invasion of Martinique of 1809 was a successful British amphibious operation against the French West Indian island of Martinique that took place between 30 January and 24 February 1809 during the West Indies Campaign 1804–1810 of the Napoleonic Wars. Martinique, like nearby Guadeloupe, was a major threat to British trade in the Caribbean, providing a sheltered base from which privateers and French Navy warships could raid British shipping and disrupt the trade routes that maintained the British economy. The islands also provided a focus for larger scale French operations in the region and in the autumn of 1808, following the Spanish alliance with Britain, the Admiralty decided to order a British squadron to neutralise the threat, beginning with Martinique.
