The 5 Biggest Civil War Battles by Charles River Editors

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.

With that advantage, Hooker proposed a daring and aggressive two pronged attack that aimed to keep Lee’s army occupied in front of Fredericksburg while marching around its left. Meanwhile a cavalry raid well in the rear was intended to cut Lee’s lines of supplies and possibly retreat. Hooker’s plan initially worked perfectly, with the division of his army surprising Lee. At the end of May 1, Lee was outnumbered 2-1 and now had to worry about threats on two fronts.

Incredibly, Lee once again decided to divide his forces in the face of the enemy, sending Stonewall Jackson to turn the Union army’s right flank while the rest of the army maintained positions near Fredericksburg. The Battle of Chancellorsville is one of the most famous of the Civil War, and the most famous part of the battle was Stonewall Jackson’s daring march across the Army of the Potomac’s flank, surprising the XI Corps with an attack on May 2, 1863. Having ignored warnings of Jackson’s march, the XI Corps was quickly routed. The surprise was a costly success, however, as Jackson was mortally wounded after being mistakenly fired upon by his own men.

The names of history’s most famous battles still ring in our ears today, their influence immediately understood by all. Marathon lent its name to the world’s most famous race, but it also preserved Western civilization during the First Persian War. Saratoga, won by one of the colonists’ most renowned war heroes before he became his nation’s most vile traitor. Hastings ensured the Normans’ success in England and changed the course of British history. Waterloo, which marked the reshaping of the European continent and Napoleon’s doom, has now become part of the English lexicon. In Charles River Editors’ Greatest Battles in History series, readers can get caught up to speed on history’s greatest battles in the time it takes to finish a commute, while learning interesting facts long forgotten or never known.

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.
