The CSS "Stonewall" sailed from Europe to break the Union blockade in March; on making Havana, Cuba, it surrendered. Some high officials escaped to Europe, but President Davis was captured May 10; all remaining Confederate land forces surrendered by June 1865. The U.S. Army took control of the Confederate areas without post-surrender insurgency or guerrilla warfare against them, but peace was subsequently marred by a great deal of local violence, feuding and revenge killings. The last confederate military unit, the commerce raider CSS "Shenandoah", surrendered on November 6, 1865 in Liverpool.
