Watch The Civil War: Brothers Divided

April 1865: Union progress has ground to a halt at the seemingly impregnable ring of trenches built around Petersburg, Virginia. After eight attempts to storm Petersburg failed, two officers from Vermont lead a daring raid.

July 1863: An elite band of Yankee Sharpshooters defeat Robert E. Lee's troops.

Dec. 1862: Following the strategic Union win at Antietam, Federal forces clash with a massive Rebel army in the town of Fredericksburg, Virginia, in what will become the largest fight of the Civil War.

September 1862. Following a string of victories in Virginia, Confederate General Robert E. Lee brings his army north.

July 1861. In what will be the first real battle of the Civil War, untested and poorly trained Rebel and Confederate troops clash on the banks of the Bull Run River.
