With the start of the Civil War, the military situation in the United States was, naturally, of great interest to the readers of Johnson's atlas, so the firm of Johnson & Ward added this "New Military Map." The focus is on the situation of all the U.S. forts and posts throughout the country, including those in the South. As an important element in the war was the access to maritime trade, with the Union blockade of Southern ports, the firm also put in nine inset maps of various southern harbors, running from Baltimore to New Orleans.
