Q: Passage: USS Sachem was originally commanded by Captain H. W. Morris, the former U.S. Navy commander of New Orleans, and was armed with one 20lb (0.91kg) parrott rifle and four 32 pounder (15kg) cannons. The size of her crew was about fifty; she had also participated in several other historic naval engagements such as Hampton Roads and the Battle of Forts Jackson and St. Philip.
