General Hooker and Staff at Lookout Mountain. Hooker's forces of about 9,700 men had been sent from the East to reenforce Rosecrans, but until the arrival of Grant they were simply so many more mouths to feed in the besieged city. In the battle of Wauhatchie, on the night of October 20th, they drove back the Confederates and established the new line of communication. On November 24th they, too, had a surprise in store for Grant. Their part in the triple conflict was also ordered merely as a “demonstration,” but they astounded the eyes and ears of their comrades with the spectacular fight by which they made their way up Lookout Mountain. The next day, pushing on to Rossville, the daring Hooker attacked one of Bragg's divisions and forced it into precipitate retreat.
