Good or bad they were type of tough old birds that country needed.
"Portuguese" Phillips is an example
http://philkearny.vcn.com/phillips.htmFollowing the annihilation of Capt. William J. Fetterman and his command on December 21, Phillips volunteered to ride to the telegraph office at Horseshoe Station on the North Platte with Col. Henry B. Carrington's dispatches, about 190 miles in subzero weather. While the general story is that he rode alone on this perilous mission, Phillips was in fact accompanied by one Daniel Dixon to Fort Reno and by others along the way, including Robert Bailey. The pay for the service was $300 apiece for Phillips and Dixon, which they received in January, 1867.
According to the telegrapher at Horseshoe Station, Phillips, Dixon, and Robert Bailey arrived about 10 a.m. on December 25, when the dispatches were wired to the headquarters of the Department of the Platte in Omaha and to Washington. To deliver the message from Wessells to Palmer, Phillips went on to Fort Laramie, arriving at 11 p.m., where a full dress ball was in progress. The appearance of the huge form of Phillips, garbed in a buffalo overcoat, pants, gauntlets, and cap, quieted the festivities, and his message caused preparations for a rescue party, delayed in departing by deeps snows until January 6. In addition to receiving his pay, Phillips was given the best horse in Company F of the 2nd Cavalry.
