Sorry but this is simply not true. The US may have passed a law to feel better but they did not use their own ships to enforce this law for the next 50 years. Read about the Slave ship 'Wanderer' from New York. It flew the New York yacht club flag and the US flag. They certainly went to Africa and picked up slaves and delivered them to the US in 1858. http://en.wikipedia.org/wiki/The_Wanderer_(slave_ship) It must be historically noted that the Northern Yankee state of New Jersey rejected the 13th Amendment on March 16, 1865. They still had slaves and did not want to give them up. Union states of Delaware and Kentucky also rejected the 13th Amendment and would not ratify it until many years later. As for Fort Sumter... There was nothing ever proven illegal about SC seceding and taking the Fort.
