Union impression upon entering Battery Wagner on Sept. 7, 1863?

[gary]

While over 300 volumes, my library is limited and I'd like to have a first hand account by a Union soldier who entered Wagner on Sept 7, 1863.

Recall that they had besieged Wagner for 58 days. In that time, they endured poor living conditions, shelling, sharpshooting - all the time while digging their parallels and zig-zag to approach Wagner. They knew that the earlier assault of July 18 was a dismal failure and over 1,500 of their comrades were casualties. Even their vaunted ironclad monitors failed to silent the defiant Wagner. So, by the evening of Sept 6., they were a mere 25 yards away and could dash into Wagner. From deserters plans of the Battery were made and distributed to the officers who would lead the charge. The anxiety must have ran high for the soldiers who would storm it.

Anybody have any first hand accounts? UNits particpating would be Henry Guss's First Brigade consisting of the 3rd New Hampshire and 97th Pennsylvania. They would be joined by the 7th & 10th Connecticutt, 24th Massachusetts, 7th New Hampshire and 100th New York. Other units included the 4th New Hampshire and the 9th Maine. I also know that the 39th Illinois was the first to reach Wagner.

Luckily, the Corn-feds skedaddled that same evening. Anybody? TIA.
