*Ordered the first shot fired in World War I on behalf of the United States

Lieutenant Colonel Teófilo Marxuach, (July 28, 1877 – November 8, 1939), was the person who ordered the first shots fired in World War I on behalf of the United States on a German cargo liner trying to leave San Juan Bay without permission. Marxuach ordered shots from a machine gun, and from a gun in the Santa Rosa battery of the Castillo San Felipe del Morro, in what are considered to be the first shots of World War I fired by the regular armed forces of the United States against any ship of the Central Powers, forcing Odenwald to stop and to return to port.
