re: Oglesby's brigade
I was going over a wartime account of the 18th Ill. Inf. (Harland-Watkins diary) and I reached the Fort Donelson section. Thought this might be of interest:
"...Our amunition gave out after firing three hours. In the meantime the 9th, 12th and 41st, who were on our right gave back and the Rebels flanked us and poured in a murderous crossfire. The 25th Kentrucky was sent to hold them in check untill we could draw back but in place of coming to our assistance they came up in our rear and fired into us and then basely retreated leaving us to draw off as best we could under a heavy cross fire from their infantry and a severe fire from their batteries of sells, grape and canister which killed a great many. ..."
