After the massacre of the Warren train, on the same route over which Gen. Sherman and his escort traveled a few hours before, the General, almost with his own eyes, could see and readily observe that the distressing reports and conditions along the frontier were true and not exaggerated, and he personally observed just what the people had endured many times and for many years.
W.W. Duke, R.J. Winders, Peter Hart, J.R. Robinson, W.N Gaines, H.H. McConnell, and other local citizens, also reported to Gen. Sherman the extent of the crimes being constantly committed by Indians from the reservations and elsewhere.
After hearing an abundance of evidence, and being thoroughly satisfied that the citizens needed instant relief, Gen. Sherman ordered Col. McKenzie to take a force of 150 Cavalry, with thirty days provisions, and follow these Indians to the reservations, or to their place of abode.
The above story is from the book, The West Texas Frontier, by Joseph Carroll McConnell.
