On July 21, 1861, the first major battle of the Civil War was fought. 35,000 Northerners marched to Manassas, Virginia to challenge more than 20,000 Southerners. We'll see how both sides were driven by new-founded pride and politics.

In 1862, General Grant advanced into Tennessee, aiming to capture its vital waterways. On April 6, Confederate forces under General Albert Johnston caught Union forces by surprise near Shiloh Church.

In September 1862, Robert E. Lee invaded the North for the first time and met the Union army along the banks of Maryland's Antietam Creek, which became the sight of the bloodiest single day in U.S. military history.

On December 13, 1862, Union General Ambrose Burnside mounted a massive, yet futile frontal assault on Robert E. Lee's Confederate troops outside of Fredericksburg, Virginia.

In May 1863, in the wilderness of Virginia, the Union Army under newly appointed General Joseph Hooker launched a massive assault on the Confederates.

In September 1863, along the Chickamauga River in northern Georgia, the Union and Confederate Armies battled to the death. In Cherokee, Chickamauga means "River of Blood"--to the soldiers who fought there, it was the vortex of hell.

In 1864, General Grant doggedly pursued Lee's forces and met them at Cold Harbor.

During the epic siege at Petersburg, Virginia, the Union forces hatched a daring plan. They dug directly beneath the Rebel forces and exploded four tons of black powder, creating a massive crater!
