June 27, 1864, daylight.
The battle comes off to-day. It will be opened on the flanks at 6 a.m. We do not commence until 8 a.m. Our brigade and one from each of the other two divisions of the corps are selected to charge the mountain. The 17th A. C. will try the left hand mountain. If we are successful with a loss of only half our number in this mountain charging, I will think our loss more than repaid. I believe we are going to thoroughly whip Johnston to-day, and if we fail I do not care to live to see it.
