It was found, after the organization of the several Congressional District regiments had been completed, that more companies and been offered than places had been provided for, and the Twenty Fifth Michigan Infantry was constituted from the surplus. It was ordered into rendezvous at Kalamazoo, and H. G. Wells, Esq., placed in command of the camp.

Colonel Orland H. Moore, then a captain in the U. S. army, who had been Lieutenant Colonel of the Thirteenth Michigan was appointed its colonel, under whose direction it had been drilled and disciplined and took the field as its commander.

The regiment was stationed at this point until December 8^th following when it was ordered to Munfordsville where it became engaged in a skirmish with the enemy on the 27^th. Thence it moved to Bowling Green, January 8^th, 1863 where it was employed on provost and picket duty, and in guarding railroad trains until March 26^th, when it proceeded to Lemanon and took part with the troops under General Manson, in pursuit of the rebels under Pegram.

On June tenth, five companies, D.E.F.I and K under Colonel Moore were ordered to Lebanon, and then marched to Green River Bridge near Columbia and n the Fourth of July following were attacked at Tebb’s Bend by a largely superior force of the enemy, under General John H. Morgan, who summoned then to surrender. Colonel Moore replied that the fourth of July was not a proper day for such a proposition, the fight lasting three and a half hours when General Morgan retired with a lost of fifty killed, among which were a Colonel, two majors, five captains and six lieutenants and two hundred wounded. The contest was one of great obstinacy, and at times the enemy occupied one side of the temporary breastworks of fallen timer, while the men of the Twenty Fifth held the other. After the battle, the enemy under a flag of truce requested permission to bury its dead, which was granted. For this defense the thanks of the Kentucky Legislature were tendered unanimously and by acclamation to Colonel Moore and his comrades of the Twenty Fifth, whose repulse of Morgan at this crises by which that leader lost thirty hours of time, "had save Lebanon and Louisville" as was stated, "from sack and pillage".
