May 15, 1862
The Civil War began on April 1861 with Confederate artillery firing on Fort Sumter in Charleston Harbor, South Carolina. Nine, months later, the United States Coast and Geodetic Survey issued its first map in its “Historical Sketch of the Rebellion” series that tracked the “limits of the loyal states as of March, 1861; May, 1862; July, 1861; May, 1862; July, 1862; and July 1863. In addition to the printed maps, a manuscript draft depicts three lines of advance. The blue line on the map indicates the “line occupied by U.S. forces previous to the genl. forward movement, whilst perfecting preparations…”; the green line indicates positions of U.S forces “after the first advance“; while red indicates the lines “at the present time” .
