It is rare for any soldier to attain the rank of general, but Albert Sidney Johnston managed that feat in three armies: rising from private to brigadier general in the army of the Republic of Texas, brevet brigadier general in the United States Army, and full general in the Confederate States Army. On April 3, 1862 he led his newly created Army of Mississippi out of the town of Corinth, Mississippi and began the march which would end in the surprise Confederate attack in the early morning of April 6, 1862, the beginning of the two day mammoth battle known to history as Shiloh.
The battle would result in the death of Johnston, his dying caused probably by his act of mercy in dispatching his personal surgeon to attend a wounded Union officer and none of his remaining staff having the presence of mind to fashion a tourniquet to stanch Johnston’s bleeding after he was wounded, and the fighting would inflict over 23,000 total Union and Confederate casualties, exceeding in two days all of the battlefield casualties in all of America’s wars prior to the Civil War. Shiloh told the nation, North and South, that this was going to be a very grim war, and that their adversary would fight it with all the strength and will that they could muster. After Shiloh the myth of a quick victorious war died on both sides.
