I'm loving this discussion between our artillery experts.
I don't know enough to even comment, but from everything I've read, I have seen stats on the Confederate artillery lost during the Vicksburg Campaign.
Each account is slightly different.
From Bearss to Grabau, and others . . . the exact number of lost field pieces don't match.
I understand this.
Not much time to keep records during Grant's unexpected amphibious assault at Bruinsburg, the rapid battles at Grand Gulf, Port Gibson, Raymond, Champion's Hill, Jackson and the Big Black River.
However, the inventory of heavy artillery that was abandoned along the Yazoo River emplacements leaves me scratching my head.
Yeah, I understand the logistics involved with moving such large guns down to Vicksburg on short notice, but I've wondered why at least a few of these guns couldn't have been moved into the Vicksburg defensive works.
