Quote from Robert E. Lee “(The service from the American battery) was terrific, and the shells thrown from our battery were constant and regular discharges, so beautiful in their flights so destructive in their fall.

Emigrant William Kilgore: "Buffalo extended the whole length of our afternoon's travel, not in hundreds, but in solid phalanx. I estimated two million." Emigrant John Wyeth: "We saw them in frightful droves as far as the eye could reach; appearing at a distance as if the ground itself was moving like a sea.“
Emigrant Isaac Foster: "The valley of the Platte for 200 miles; dotted with skeletons of buffalos; such a waste of the creatures God had made for man seems wicked, but every emigrant seems to wish to signalize himself by killing a buffalo." Slaughtered buffalo lying dead in the snow in 1872.
