Viertageschlacht
The result was the Four Days' Battle, one of the longest naval engagements in history. Despite administrative and logistic difficulties, a fleet of eighty ships under General-at-Sea Monck, the Commonwealth veteran, (after the Duke of Albemarle) set sail at the end of May 1666. In his official capacity Clarke attended Monck aboard the Royal Charles. The Four Days' Battle began on June 1. On the 2nd day, Clarke's right leg was shattered by a cannonball. Monck reported that "he bore it bravely" but, two days later, Clarke died. His body was buried at Harwich.
