From the first shots fired at Fort Sumter in 1861 to the surrender at Appomattox in 1865, four years of Civil War raged in the United States. A century and a half later, battlefields echo with the stories of young men caught up in the most costly conflict in our history. Iconic images invoke images of the war. Some of those images are depicted here: The profile of President Abraham Lincoln (blue), General Robert E Lee on his beloved horse, Traveler (gray), the kepi hat worn by bother Union and Confederate soldiers (yellow), ironclad battleships (black), rifles (red), and cannons (brown).
