Jacob D. Cox, Military Reminiscences of the Civil War…
“ Through my army life I met more or less of the same conduct when assigned to a new command; but when men learned that discipline would be inevitably enforced, and that it was as necessary to obey a quiet order as one emphasized by expletives, and especially when they had been a little under fire, there was no more trouble. Indeed, I was impressed with the fact that after this acquaintance was once made, my chief embarrassment in discipline was that an intimation of dissatisfaction on my part would cause deeper chagrin and more evident pain than I intended or wished. ”
