While the amphibious assault ship USS Bataan arrived in Haiti yesterday and the hospital ship USNS Comfort arrived the day before, naval ships are not the only vessels sailing to aid the earthquake victims. The schooner Amistad is on her way bearing both supplies and a sense of history. The schooner Amistad , a replica of the slave ship on which the captives revolted and took over the ship in 1839, is sailing to the only nation in the western hemisphere to achieve independence through a slave rebellion.
