Perryville Battlefield Location Photos
The 26th OVI was part of the 2nd Corps under General Thomas Crittenden at the Battle of Perryville, Kentucky. The 2nd Corps occupied the right flank being located in the area north of Lebanon Pike and south of the Springfield Pike.  The  battle action began  at the opposite flank approximately 1 mile to the north, with the 1st Corps under General McCook.  For what ever reason, the 2nd Corps of nearly 22,000 men was not ordered to get involved in the action until the day was nearly over. 

At the end of the battle on October 8, 1862, the 2nd Corps was ordered to advance northeastward into Perryville, but only found Confederate rear action troops as Bragg's Confederate army had decided to retreat towards Harrodsburg.  The photos below are of the probable position of the 2nd Corps being taken just southwest of Perryville, south of the Springfield Pike and north of the Lebanon Pike.
