Federal reserve position of Emerson Opdycke's Brigade
This old gymnasium is likely to be torn down in the near future to expand the present-day Carter grounds on the ground where much of the Battle of Franklin was fought.
This is the spot directly north behind the present day Carter House area. Col Emerson Opdycke's brigade was placed in this vicinity in reserve. When the Confederate's broke through near the Carter House Opdycke's brigade came rushing headlong through this ground to push back the assault. The repulse was led by Captain E.P. Bates of the 125th OVI, a graduate of Hillsdale College.
Reilly’s troops were not alone in their effort to shove the enemy back. Emerson Opdycke’s charge occurred at essentially the same time as Reilly’s, but because of the limited space in which Opdycke’s Brigade had to maneuver, some of his troops ended up assisting Reilly. The 44th Illinois and the 74th /88 th Illinois from Opdycke’s Brigade operated exclusively east of the pike and moved up behind the 175th Ohio.
