Americans have long been fascinated by the Civil War, marveling at the size of the battles, the leadership of the generals, and the courage of the soldiers. Since the war's start over 150 years ago, the battles have been subjected to endless debate among historians and the generals themselves. The Civil War was the deadliest conflict in American history, and had the two sides realized it would take 4 years and inflict over a million casualties, it might not have been fought. Since it did, however, historians and history buffs alike have been studying and analyzing the biggest battles ever since.

By the close of 1864, Abraham Lincoln had been reelected, the Union army had taken Nashville from General Hood, and Sherman had concluded his total war, "slash-and-burn" march of destruction to Savannah, Georgia, offering it as a Christmas present to Lincoln. Nevertheless, with everything seemingly falling to pieces, the South still held out hope of some sort of miracle, and Davis even attempted to send a peace delegation to meet with Lincoln in the early months of 1865. To most observers, the South was clearly reaching its end, but Davis had no intention of quitting the war. Even while he was fleeing, he attempted to order Confederate generals in the field to keep fighting. On April 9, 1865, Lee formally surrendered his weary army to Grant at Appomattox. Appomattox is frequently cited as the end of the Civil War, but there still remained several Confederate armies across the country, mostly under the command of General Joseph E. Johnston, the same commander who arrived with reinforcements by rail during the First Battle of Bull Run and gave the South hope with victory in the first major battle.

On April 26, 1865, Johnston defied Davis's orders and surrendered all of his forces to General Sherman, and over the next month, the remaining Confederate forces would surrender or quit.
