USS Merrimac

USS Merrimac was a United States Navy collier during the Spanish–American War. It was the only American vessel sunk by the Spanish navy in that conflict.

Merrimac, a steamship, was built by Swan & Hunter shipyard as SS Solveig in Wallsend, England, in November 1894. It was purchased by the US Navy in April 1898. Rear Admiral William T. Sampson ordered her to be sunk as a blockship at the entrance of Santiago Harbor, Cuba, in an attempt to trap the Spanish fleet in the harbor.
