Notes and References

1. Eicher p.401 Mower was wounded in the neck and captured on October 4 but was recovered by Union forces the same day
2. McPherson arrived at Corinth on October 4 at about 4:00 p.m. according to his report (O.R. Ser. I, Vol. XVII, Part I, p. 367)
3. Detachments of the 8th, 12th, and 14th Iowa and 58th Illinois whose members survived encirclement in the Hornet's Nest at Shiloh, were collectively known as the "Union Brigade", a regiment sized command under the command of Ltc John Coulter. (O.R. Ser. I, Vol. XVII, Part I, p. 175)
4. Du Bois was serving as aide-de-camp to Rosecrans until he was detached from staff duty to assume brigade command after Baldwin's wounding (Cozzens page 228)
5. Eicher p.370
6. Cozzens p.151–154. Early on the morning of October 3, orders were given placing McKean (who outranked McArthur) in command of the Sixth Division. Unknowingly no orders were given to reassign McArthur and he was without a command as preparations for the battle began. A staff officer at Rosecrans' headquarters remembered this and a special order was sent assigning McArthur to command the 1st Brigade.
7. Hickenlooper's report gave the number of 6th Division guns (16). In addition, Battery F, 2nd Illinois had 2 guns detached at Bolivar and the 3rd Ohio Battery had 4 guns detached at Bolivar. (Official Records 1886 p. 336)
