Before Vicksburg, Miss., Tuesday, May 19. We are lying in the reserve of the battle line before Vicksburg, having been pushed forward at double quick. General Grant gave them till 11 A. M. to surrender, but they did not avail of it. Firing is going on with Parrott pieces in front but not very brisk. 1 P. M. The 1st Section (Rifled) have gone to the left with Lieutenant Clark. The other pieces were brought into action in front, and laying in the reserve. Brisk cannonading all around with sharp musketry at times—McArthur has taken a fort and guns. Sherman drove them about a mile on the right. McClernand holds his own on the left. Both wings said to have joined the Mississippi. Pontoon train passed to the right in great hurry at 4 P. M. to be thrown toward the Yazoo.
Darkness closed hostilities and we limbered up and passed to the front about a mile, and planted our battery on a hill, very steep and high, doubling teams to go up. Relieved the 11th Ohio who had been engaged all day against a fort, using up all their ammunition. Cannoneers silently set to work levelling off a position; the horses unhitched and tied under a gin house. We lay down on the bare, rough ground, clothes all on, but it prevented not our sleeping.
