August 20, 1864: Base of Madera Peak
Hoffmann and Gardner went on peak. I took pills. Had to take an enormous quantity before they would operate so when they did was rather sick. Lay in camp all day. Hoffmann came back down sick with a lame leg that has been troubling him for some days without any known cause….
I resolved to push out. I was getting run down, felt nearly sick, our provisions were low, and Hoffmann was getting rapidly worse.
