On the 18th, six companies, under command of Lieut. Col. Phillips, started on a scout about dark, after a party of guerrillas who had made a dash upon some of the Home Guards at Middleton, killing and taking prisoners several of them. They pursued them all night, in the direction of Bolivar, but could not find them. Returned to camp about noon the next day.

On the 20th of July, the Regiment moved South, accompanied by two guns of Tamrath's Battery. At Hopkins we were joined by the 11th Ill. Cavalry, commanded by Major Kerr. Moved on to within three miles of Ripley, and bivouacked at the forks of the Nubbin Ridge and Ruckersville road. Two companies of Cavalry and two companies of Mounted Infantry were sent towards Ripley to reconnoiter. Discovering no enemy, they soon returned. On the 21st, the command moved back seven miles to Ruckersville, and there awaited orders from Corinth. We moved forward again on the 22d, at 3 A. M. Halted at Ripley two hours. Captured two prisoners, and then moved back to camp at Pocahontas.

The Regiment moved North-west, at daylight on the 20th of July, with eight days rations. It joined Col. Hatch's command, North of Bolivar, at 8:30 P. M., of the same day. After the Regiment was formed, before marching, a brief prayer was offered by the writer, who was then present with the Regiment. Bivouacked for the night, ten miles North of Bolivar. On the 27th, Lieut. Col. Phillips was ordered to the command of a Brigade, consisting of the 9th Ill. Inft. and 3d Michigan Cavalry, and Captain G. G. Lowe took command of the Regiment. We joined Col. Prowitt's command at Lexington, Tenn., on the 28th. Passed through Clarksville, a Union town, to-day. Had captured a goodly number of mules and negroes, and about 100 prisoners up to this date. Among the latter were two Colonels. Passed through Huntingdon on the 29th. A strong Union town. While stopped here, two daughters of Col. Hawkins of the 2d West Tennessee Cavalry, (loyal,) paraded the streets, carrying the stars and stripes. This was cheering to our boys. We lay over most of the 29th at Macedonia. Moved to Trenton on the 31st. Passed through a very rough country, and in a poor state of cultivation. From Trenton we proceeded South, towards Jackson, passing through Jackson on the 1st of August, and reaching camp at Pocahontas on the 3d of August, about 8 P. M.

The Regiment was out, during this scout, nine days. Did not have any engagements with the enemy.

On the 6th of August, Companies A, C, D, E, G, H, I and K, under command of Lieut. Col. Phillips, moved North-west of Bolivar, and returned on the 7th, without finding any forces of the enemy.

On the 12th of August, at 10 P. M., the Regiment moved South, with six days rations. Marched all night, and halted at sunrise and fed. At 6 A. M., of the 13th, we were on the march again. Took the road through Salem, passing that place about 4 P. M., and bivouacking for the night six miles beyond it. Moved forward again at daylight on the 14th, crossing the Tallahatchie at Rocky Ford, and bivouacking for the night. Moved West on the Oxford road, early on the 15th, reaching that place at noon. Here we joined a Brigade from LaGrange. Lieut. Col. Phillips assumed command of the Brigade, and moved on six miles beyond Oxford, on the Coffeeville road, and bivouacked for the night. At daybreak, on the 16th, moved forward again. We were joined to-day, by a Brigade of Cavalry from Germantown and Collierville, under the command of Lieut. Col. M. R. M. Wallace, who being junior officer to Lieut. Col. Phillips, reported his command to him for orders. Lieut. Col. Phillips now assumed command of the whole force, consisting of two Brigades. Lieut. Col. Wallace had command of the 1st Brigade, and Major Coon of the 2d.

The whole force crossed the Tochamy River on a ferry boat, and reached Water Valley at 12 M. Here our advance captured a train of seven six-mule wagons, and a number of prisoners who were guarding the train. The 1st Brigade was so long delayed in crossing the river, that Major Coon, who had command of the 2d Brigade, did not leave Water Valley until 5 P. M. He then moved forward to within two miles of Coffeeville, and bivouacked for the remainder of the night. It was 2 A. M., of the 17th, when we reached that point.

A heavy storm of rain came on shortly after leaving Water Valley, and the night became intensely dark. The darkness made it very difficult to march at all. Often the mules, with their riders, would tumble into the ditches. The 1st Brigade, commanded by Lieut. Col. Wallace, moved only one mile from Water Valley, when the darkness became so intense, that movements were almost impossible. The Brigade was consequently ordered into bivouack for the night. On the morning of the 17th, Lieut. Col. Wallace joined the 2d Brigade at Coffeeville. The entire force now moved forward rapidly towards Grenada, the 11th Ill. Cavalry having the advance. When ten miles from Coffeeville, six or eight locomotives and 40 or 50 cars were captured, and a guard placed over them. When the advance were within four miles of Grenada, the Rebels fired the two large Railroad bridges over the Tallobusha, and before we could reach them, they were completely destroyed. The 11th Ill. Cavalry was ordered forward, as rapidly as possible, to prevent the unnecessary destruction of property; and the entire 2d Brigade moved forward at a brisk trot. When within one mile of town, the 11th Cavalry were checked by about 300 of the enemy. The 9th Ill. Inft. were dismounted and sent forward as skirmishers. Soon after, the 2d Iowa and 3d Michigan Cavalry went into the action. Orders were sent back to Lieut. Col. Wallace to hasten up his Brigade, and move forward with all possible dispatch. As soon as the Battery was placed in position, Col. Wallace was ordered to enter town, with his Brigade, by the lower ford. The enemy not replying to our Battery, Major Coon was ordered to charge across the ford, with the 2d Iowa Cavalry, and at the same time to ferry over a portion of the 9th Ill. Inft. as a support, in case the enemy pressed him too hard. This force crossed and took possession of the town, without further opposition.

The captures which we made, were as follows: 60 locomotives; 450 cars, of all kinds; considerable stores, and $8,000 in Confederate scrip.

As the enemy had burned the bridges across the Tallobusha, making it impossible to run off the rolling stock, the cars, locomotives, machine shops, depots, Commissary and Quartermaster buildings were fired, and destroyed.
