Raid on the Medway The Raid on the Medway during the Second Anglo-Dutch War in June 1667, sometimes called the Battle of the Medway, Raid on Chatham or the Battle of Chatham, was a successful and daring attack conducted by the Dutch navy deep upriver targeting the largest English naval battleships at a time when most were virtually unmanned and unarmed, laid up due to lack of funding in the fleet anchorages off Chatham Dockyard and Gillingham in the county of Kent. At the time, the fortress of Upnor Castle and a barrier chain called the "Gillingham Line" were supposed to protect the mothballed naval ships anchored off Chatham, the main English naval base in southeastern Stuart England.
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.
