Army of the Ohio

Don Carlos Buell organized the Army of the Ohio from distinct military divisions within the Department of the Ohio, which he was put in command of in November, 1861. The Battle of Mill Springs was the first battle in which its men fought.

In February, 1862, Buell's Army of the Ohio moved south with Ulysses S. Grant's Army of Tennessee, taking the city of Nashville, Tennessee, following the fall of Fort Donelson. It was the first Confederate capital to fall under Union control. From Nashville, the Army of the Ohio moved south to the town of Savannah, Tennessee. When Grant awoke to the sound of battle on April 6, 1862, he issued orders to Buell's lead division, under the command of William 'Bull' Nelson, to advance to Pittsburg Landing in support of the Army of the Tennessee. Nelson would be the first of Buell's three divisions to arrive in support of Grant at the Battle of Shiloh.

Following the advance on Corinth, Mississippi, the Army of the Ohio was ordered east to take the important railroad hub of Chattanooga, Tennessee. Braxton Bragg's renamed Army of Tennessee beat Buell to the prize city because rear-area security problems and logistics slowed the Army of the Ohio to a crawl. Buell had spread his army in a line stretching more than 400 miles from Pikeville, Kentucky to Battleground, Alabama and learned first-hand the meaning of the old maxim, "Defend everything and you defend nothing at all."
