Recruits for all the companies had been mustered in prior to the dates shown, which are the

dates the companies were considered complete, and captains appointed.

This regiment has no connection with Colonel John K. Miller's regiment, which was originally

called the 12th, but later designated the 13th Regiment. Although it was begun in August, 1863, it

was not until February 22, 1864 that as many as six companies had been mustered; it was at this

time that George Spalding was commissioned lieutenant colonel. He was commissioned colonel

when the regiment's 12th company was organized in August, 1864. All of the original field officers

and many of the company officers had seen previous Service in other units from north of the Ohio

River. Colonel Spaldmg had previously been lieutenant colonel, 18th Michigan Infantry; Lieutenant

Colonel Hoeflinger and Major Kirwan came from the 4th U. S. Cavalry.

On January 31, 1864, the 12th Tennessee Cavalry, Captain John S. Kirwan, was reported in

Brigadier General Alvan C. Gillem's command, which was stationed along the Nashville and

Northwestern Railroad. At that time, the regiment consisted of only two companies.

The regiment was assigned to the 2nd Brigade, Brigadier General Gillem's 4th Division, Cavalry

Corps, Department of the Cumberland. On April 14, Lieutenant Colonel Spaldmg was given

command of the brigade, and Major Kirwan commanded the regiment. The regiment did duty along

the Nashville and Northwestern Railroad until May 27, when it returned to Nashville, and on May 31

was reported at Gallatin. In June the brigade was ordered to Tullahoma, and from there to Decherd,

on the line of the Nashville and Chattanooga Railroad. Captain J. C. Rogers, Co. "E", was killed

June 14, in one of the skirmishes in which the regiment was involved. On June 23 the regiment was

ordered to Pulaski where it remained stationed for some time.

In August, 1864, the regiment clashed with Brigadier General Philip D. Roddey's forces near

Florence, Alabama, where Lieutenant Cunningham, Co. "L", was killed; and with Colonel Jacob

Biffie's forces at Clifton, Tennessee. Colonel Spalding assumed command of the division August

18, 1864, General Gillem having gone on an expedition into East Tennessee. On August 31 some

detachments were still reported on the Nashville and Northwestern Railroad, but Lieutenant Colonel

Hoefling was reported in command of the regiment. The division at that time was in the District of

Northern Alabama, of which Brigadier General R. S. Granger was the commanding officer.

On August 26, the regiment moved with the brigade from Pulaski to Tullahoma, where it joined

the forces of Major General Robert H. Milroy, in several days' fighting with Confederate forces under

Brigadier General John S. Williams, along the line of railroad from Tullahoma to Nashville, the most

serious of which was at Triune on September 5, 1864. From there it moved to Pulaski, and joined

Major General Lovell H. Rousseau at Shoal Creek, Alabama, in pursuit of Major General Wheeler,

but returned to Pulaski on September 12.

On September 21, Colonel Spalding was ordered to drive General Roddey from the Shoal Creek

area, and had started on that mission when Major General Nathan B. Forrest started his raid into

Middle Tennessee. Spalding hastily turned in pursuit of Forrest, and the regiment was engaged at

Sulphur Branch Trestle on September 26; at Richland Creek September 27 and 28; and at Pulaski

September 28. Here the regiment lost two officers wounded, and two men killed, 20 wounded.

On September 30, the regiment, with Major Kirwan in command, was back at Pulaski, where

Brigadier General John C. Starkweather was in command of the post. Lieutenant Colonel Clift, 5th

Tennessee Cavalry, was at this time in command of the brigade.

On October 12, Major General George Thomas ordered the 10th and 12th Tennessee Cavalry to

be remounted, and join Brigadier General John T. Croxton near Florence, Alabama for the purpose

of watching General John B. Hood's Army, and, if possible, preventing its crossing the Tennessee

River. On November 5, General Croxton reported: "Colonel Clift, commanding the 10th and 12th

Tennessee Cavalry, left the road I had them covering and struck the Huntsville Road in my rear. I

sent him back to Lexington (Alabama). On November 7, a scout of 50 men from the 12th

Tennessee was sent out to protect the railroad between Columbia and Pulaski."

On November 10, the regiment was transferred to the 5th Division, Brigadier General Edward

Hatch, who was instructed to send the dismounted men to Nashville for remount. On November 26,

258 men of the 12th, having been remounted and re-equipped, left Nashville and arrived at Franklin.

General Hatch assigned the regiment to the 2nd Brigade, under Colonel D. E. Coon, and Colonel

Spalding returned to command of the regiment. While enroute to join the brigade, the regiment had

a severe skirmish near Spring Hill on November 30, but joined the brigade near Franklin in time to

take part in heavy fighting with Confederate forces under Generals W. H. Jackson and A. Buford,

along the Harpeth River, while the infantry of both armies were waging the battle of Franklin. The

regiment in Hatch's 5th Division took a prominent part in the battle of Nashville, December 15-16,

1864, and in the pursuit that followed. On December 15, on the Harding Pike, the regiment captured

the train of Brigadier General J. R. Chalmers; 14 wagons loaded with records, clothing and forage,

along with 43 prisoners. On the 16th, after participating in the fighting that broke the Confederate

lines, the regiment pursued out the Granny White Pike in an attempt to reach Franklin in advance of

the Confederates. "After proceeding about a mile they came upon the enemy's cavalry under

Chalmers, posted across the roads, and behind barricades. The position was charged by the 12th

Tennessee Cavalry, Colonel Spalding Commanding, and, the enemy's lines broken, scattered him

in all dfrections, and capturing quite a number of prisoners, among them Brigadier General E. W.

Rucker." So read General Thomas's official report.

In this engagement the 12th Tennessee Cavalry U. S. A. clashed with the 12th Tennessee

Cavalry C. S. A. Captain Boyer, of the 12th, had a hand-to-hand fight with Colonel Rucker, then

commanding a brigade. Each wrested the sabre of the other from his hand. One account says

Captain Boyer then drew a pistol and shot Rucker in the arm. Another account says Rucker was

shot by an unknown soldier standing near by. The flag of Rucker's Brigade was also captured.

The regiment took part in the pursuit of Hood's Army as far as Bambridge, Alabama, on

December 28, 1865. In January, it was ordered to Eastport, Mississippi, then to Gravelly Springs,

Alabama, where it arrived January 14. On February 7, 1865, it moved back to Eastport, where it

remained until May 11, 1865.

On April 18, 1865, Spalding, now a Brigadier General, was given command of the 1st Brigade,

5th Division, and the regiment was transferred from the 2nd Brigade to the 1st Brigade. On May 11

it left Eastport for St. Louis, Missouri, with orders to report to Major General John Pope. At St. Louis,

it was remounted and refitted and sent to Fort Leavenworth, Kansas, to report to Brigadier General

R. B. Mitchell, Commanding District of North Kansas. On June 1, 1865, at Benton Barracks,

Missouri, the regiment was reported with 464 enlisted men, horses drawn 485. On June 12, two

companies were assigned to garrison duty at Fort Leavenworth, and the balance of the regiment

served as escort for a party of surveyors and scouted the country through Southern Nebraska and

North Kansas.

On September 3, it was ordered to return to Fort Leavenworth to be mustered out. It was

mustered out of service there on October 7, 1865, and returned Nashville for final payment and

discharge.
