Philip Henry Sheridan, Personal Memoirs of P. H. Sheridan…
“ The second day, after marching for hours through vast herds of buffalo, we made Hackberry Creek; but not, however, without several stampedes in the wagon-train, the buffalo frightening the mules so that it became necessary to throw out flankers to shoot the leading bulls and thus turn off the herds. In the wake of every drove invariably followed a band of wolves. This animal is a great coward usually, but hunger had made these so ravenous that they would come boldly up to the column, and as quick as a buffalo was killed, or even disabled, they would fall upon the carcass and eagerly devour it. ”
