This animated map shows Gettysburg in a whole new way

The Civil War Trust, known for its great maps and historical accounts of the war, has branched into animated maps that show move-by-move accounts of important battles like Antietam, Vicksburg and Shiloh.

The trust's still maps are known for their accuracy and detail, and these new animated maps continue that tradition. The big difference is the motion; it's like watching the battle play out on a sand table during a ROC drill.

A narrator provides context for the action, telling viewers everything from how the crippling heat affected the repeated clashes at Little Round Top to why Maj. Gen. Daniel Sickles made his ill-advised deployment of artillery on the Union's front.

Meanwhile, short video clips try to put the viewer on the ground with soldiers during the most fierce and important events, showing things like when Maj. Gen. John Reynolds was shot in the neck and killed.

The full videos for each battle are a little long, about 15-20 minutes each. But they let you get a better understanding of each battle that you can knock out in a lunch break. Check out Gettysburg below:
