We took up our line of march from the battle-field at Vicksburg on the 5th day of July, the after the surrender, and, after a five days' very fatiguing march, without anything particularly marked in our course, expect much suffering with the extreme heat, we reached the neighborhood of the rebel fortification at Jackson.

On the 9th of July, we took up our line of march and advanced toward the enemy's line When within 2 miles of the enemy, the advance of the First Brigade encountered the rebel pickets, immediately after which the action commenced.

General Hovey, commanding, directed me to form my brigade to the left of the Raymond road and forward the whole column, which was speedily executed, and we advanced to Lynch's Creek. Here I advanced two companies of the Forty-seventh Indiana Infantry as skirmishers across the creek. As soon as they crossed the creek, the enemy opened fire upon them, to which the skirmishers spiritedly replied, and, after a contest of about thirty minutes, drove the enemy from the field. While the skirmishers were contesting the ground, I advance the whole command the creek and formed directly on the bank. We advanced no farther that night, the men lying upon their arms all night, with a strong picket line in front.

During the next seven days the siege continued, the men of my command during and intrenching, the sharpshooters in advance striking, wounding, and killing all who exposed their person to the unerring aim of our riflemen, until the morning of the 17th, when it was announced by our pickets that the rebel had evacuated during the night. I sent forward a line of skirmishers, who soon verified the truth of the conjecture by talking possession of the enemy's works and raising the Stars and Stripes thereon.

During the whole time of the siege the officers and men conducted themselves with great bravery and skill, living three days on less than fourth rations. They endured all without a murmur, and witnessed the
