In addition to the supplies transported by boat, the men were to carry forty rounds of ammunition in their cartridge-boxes, and four days' rations in haversacks.
In the battle of Chattanooga, troops from the Army of the Potomac, from the Army of the Tennessee, and from the Army of the Cumberland participated.

In fact, the accidents growing out of the heavy rains and the sudden rise in the Tennessee River so mingled the troops that the organizations were not kept together, under their respective commanders, during the battle.

Hooker, on the right, had Geary's division of the 12th corps, Army of the Potomac; Osterhaus's division of the 15th corps, Army of the Tennessee; and Cruft's division of the Army of the Cumberland.

Sherman had three divisions of his own army, Howard's corps from the Army of the Potomac, and Jefferson C.Davis's division of the Army of the Cumberland.

There was no jealousy--hardly rivalry.
