The naval part of the war ended more slowly. It had begun on April 11, two days after Lee's surrender, when Lincoln proclaimed that foreign nations had no further "claim or pretense" to deny equality of maritime rights and hospitalities to US warships and, in effect, that rights extended to Confederate ships to use neutral ports as safe havens from US warships should end. Having no response to Lincoln's proclamation, President Johnson issued a similar proclamation dated May 10, more directly stating that the war was almost at an end and insurgent cruisers still at sea, and prepared to attack US ships, should not have rights to do so through use of safe foreign ports or waters. Britain finally responded on June 6, by transmitting a letter from Foreign Secretary
John Russell, 1st Earl Russell, to the Lords of the
Admiralty withdrawing rights to Confederate warships to enter British ports and waters. US Secretary of State Seward welcomed the withdrawal of concessions to the Confederates. Finally, on October 18, Russell advised the Admiralty that the time specified in his June message had elapsed and "all measures of a restrictive nature on vessels of war of the United States in British ports, harbors, and waters, are now to be considered as at an end". Nonetheless, the final Confederate surrender was in Liverpool, England where
James Iredell Waddell, the captain of
CSS , surrendered the cruiser to British authorities on November 6.
