The Raid on the Medway, during the Second Anglo-Dutch War in June 1667, was a successful attack conducted by the Dutch navy on English warships laid up 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 English ships.
