Note: The following is one of a series of columns about early shipping in Georgia and Bulloch County. As World War I in Europe spread, both the City of Birmingham and the City of Chattanooga, the Savannah Line's newest vessels, made sailings with both passengers and cargo, while the City of Atlanta, the City of Montgomery, the City of Saint Luis and the City of Savannah carried only cargo. When America finally entered the war, German submarines began sinking American ships.
