 A surprise attack in June 1667, the Raid on the Medway, on the English fleet in its home port arguably won the war for the Dutch; it is considered to be one of the most humiliating defeats in British military history.A flotilla of ships led by Admiral de Ruyter sailed up the Thames Estuary, broke through the defences guarding Chatham Harbour, set fire to ships of the English fleet moored there, and towed away and the Royal Charles, the pride of the English fleet.Also in June 1667, the Dutch sailed a vessel from New Amsterdam into what is now Hampton Roads, Virginia, destroying a British ship in the harbour and attacking its fort.
