The Four Days' Battle was a naval engagement fought from 11 to 14 June 1666 (1–4 June O.S.) during the Second Anglo-Dutch War. It began off the Flemish coast and ended near the English coast, and remains one of the longest naval battles in history. The Royal Navy suffered significant damage, losing around twenty ships in total. Casualties, including prisoners, exceeded 5,000 with over 1,000 men killed, including two vice-admirals, Sir Christopher Myngs and Sir William Berkeley. Almost 2,000 were taken prisoner including Vice-admiral George Ayscue. Dutch losses were four ships destroyed by fire and over 2,000 men killed or wounded, among them Lieutenant Admiral Cornelis Evertsen, Vice Admiral Abraham van der Hulst and Rear Admiral Frederik Stachouwer. Although a clear Dutch victory, the surviving English ships were able to beat off an attempt to destroy them at anchor in the Thames estuary in early July. After quickly refitting, on 25 July the English defeated the Dutch in the St. James's Day Battle.
