Numbers 41. Report of Lieutenant Colonel Luther H. Whittlesey, Eleventh Wisconsin Infantry. Vicksburg, MISS., July 26, 1863.

LIEUTENANT: For the information of the colonel commanding the brigade, I have the honor to submit the following report of the operations of the Eleventh Wisconsin Infantry in the late march and attack on Jackson, MISS., and their subsequent movements up to this date:

On the morning of July 5, Conformably to orders issued the day previous, we marched from our camp and trenches in rear of Vicksburg at 6 a. m. out on the Jackson road to Clear Creek, near Black River, marching about 10 miles that day under a clear burning sun, but fortunately, finding good water at our camp.

July 6. -We marched at 4 a. m., crossing the Big Black 1 1/2 miles from our camp on Clear Creek, and proceeded some 4 miles to a plantation near Edwards Depot, where we lay upon our arms for the night. The weather was very hot, which, with poor water combined, caused some suffering among the troops.

July 7. - We broke camp at 7 a. m., marched about 8 miles, camping near the forks of the Raymond and Clinton roads. At 5 a. m. we formed line of battle, and bivouacked for the night.

July 8. - We marched at 6 p. m. ; proceeded 4 miles and camped.

July 9. - Marched at 6 a. m. ; passed through Clinton to within 8 miles of Jackson.
