The Ten Biggest Battles of the Civil War: Gettysburg, Chickamauga, Spotsylvania Court House, Chancellorsville, The Wilderness, Stones River, Shiloh, Antietam, Second Bull Run, Fredericksburg

Americans have long been fascinated by the Civil War and its biggest battles, particularly Gettysburg, Antietam, and Shiloh, all of which involved Robert E. Lee or Ulysses S. Grant. But one of the 6 biggest battles of the war, and the one that took the heaviest toll by % on both armies was fought at the end of 1862 in Tennessee, and it involved neither of those generals.

In late December 1862, William Rosecrans’s Union Army of the Cumberland was contesting Middle Tennessee against Braxton Bragg’s Army of Tennessee, and for three days the two armies savaged each other as Bragg threw his army at Rosecrans in a series of desperate assaults. Bragg’s army was unable to dislodge the Union army, and he eventually withdrew his army after learning that Rosecrans was on the verge of receiving reinforcements. Though the battle was stalemated, the fact that the Union army was left in possession of the field allowed Rosecrans to declare victory and embarrassed Bragg.

Of all the Civil War battles fought, and of all the victories achieved by Robert E. Lee at the command of the Confederate Army of Northern Virginia, the Battle of Chancellorsville is considered the most tactically complex and ultimately the most brilliant Confederate victory of the war.

In early May 1863, the Army of the Potomac was at the height of its power as it bore down on Robert E. Lee’s Army of Northern Virginia near Fredericksburg, where the Confederates had defeated them the previous December. The Union behemoth had spent most of the winter season being reorganized and drilled by “Fighting Joe” Hooker, an aggressive commander who had fought hard at places like Antietam. With an army nearing 130,000 men, Hooker’s Army of the Potomac was twice the size of the Army of Northern Virginia.

Lee’s heavily outnumbered army won the most stunning victory of the war at Chancellorsville, but it cost them Stonewall Jackson. Moreover, the reorganization of the armies and the battle itself played an influential role in the way the Pennsylvania Campaign and the Battle of Gettysburg unfolded later that summer.

Without question, the most famous battle of the American Civil War took place outside of the small town of Gettysburg, Pennsylvania, which happened to be a transportation hub, serving as the center of a wheel with several roads leading out to other Pennsylvanian towns. From July 1-3, Robert E. Lee’s Confederate Army of Northern Virginia tried everything in its power to decisively defeat George Meade’s Union Army of the Potomac, unleashing ferocious assaults that inflicted nearly 50,000 casualties in all.

Day 1 of the battle would have been one of the 25 biggest battles of the Civil War itself, and it ended with a tactical Confederate victory. But over the next two days, Lee would try and fail to dislodge the Union army with attacks on both of its flanks during the second day and Pickett’s Charge on the third and final day. Meade’s stout defense held, barely, repulsing each attempted assault, handing the Union a desperately needed victory that ended up being one of the Civil War’s turning points.

After the South had lost the war, the importance of Gettysburg as one of the “high tide” marks of the Confederacy became apparent to everyone, making the battle all the more important in the years after it had been fought. While former Confederate generals cast about for scapegoats, with various officers pointing fingers at Robert E. Lee, James Longstreet, and James Stuart, historians and avid Civil War fans became obsessed with studying and analyzing all the command decisions and army movements during the entire campaign. Despite the saturation of coverage, Americans refuse to grow tired of visiting the battlefield and reliving the biggest battle fought in North America.
