Forney's Division, MGen. John H. Forney
Hebert's Brigade, BGen. Louis Hebert
Company C, 2nd Alabama Artillery Battalion
(4 guns), Capt, T. K. Emanuel
His death is noted on a number of different dates, Died June 3, 1863, killed June 8, died 3 June [Cedar Hill], on or about June 1.
His [Heberts] troops were soon in the intrenchments on either side of the Jackson road
Where the Jackson road entered the Confederate entrenchments, Confederate engineers had flanked the road with strong points - 3rd Louisiana Redan to the north, and Great Redoubt to the south.
During this period of time, no direct attack was made on the siege line at this point. However, they were exposed to an almost constant bombardment and observation of Federal sharpshooters. Nothing is stated in any document I am aware of which describes his death. Nor do we know where his battery was located, Third Louisiana Redan or Great Redoubt.
From this time [May 22] to the close of the siege, the enemy kept up an incessant fire of sharpshooting and cannonading, in the mean time planting batteries and continuing his approaches, the main points being the work on the Baldwin's Ferry road, the one on the Jackson road [3rd Louisiana Redan] , and a point midway between the Graveyard and Jackson roads. Approaches were also made on my extreme left; but this point was properly speaking, under the supervision of Major-General Smith.
On or about June 2, my [Hebert] line was contracted by closing in to the right, in consequence of its close investment and the reduction of its numbers by casualties, my left now resting midway between the Graveyard and Jackson roads. The approaches at all the above-mentioned points were brought to within easy hand-grenade distance, and mines were pushed forward under the works. The enemy made strenuous efforts to possess himself of the main work on the Jackson road, defended by the Third Louisiana Regiment, the occupation of which by him would necessitate the abandonment of our trenches for a considerable distance to the right and left, as it would give him an enfilade fire either way. Opposite this point he planted a number of heavy siege guns, with which he made a serious breach in the parapet of the redan. The fire of these guns was, however, in a great measure diverted by the fire of a 10-inch mortar, which we had planted close in the rear of our lines. We were only permitted to retain this mortar a few days, when it was again removed to the right and its place supplied by a 9-inch Dahlgren gun, which the enemy disabled the second day after it opened fire.
I would suggest you query the Historian's Office at the Vicksburg National Military Park. Emanual's Batteries location is known and marked and there should be written material of the battery in their offices. A visit would be well worth your while.
