We at the American Battlefield Trust are re-releasing our Animated Battle Maps with newly branded openings. Learn about the 48 day siege during the summer of 1863 that gave the Union Army, commanded by Ulysses S. Grant, control of the Mississippi River - thus cutting the Confederate supply line to the South. Our collection of animated maps bring battles of the American Civil War to life, complete with troop movement animations, narratives, reenactment footage and more.
