"The whole weight of all that is sensuous in an army presses for rest and refreshment. It requires exceptional vigor on the part of a commander to see and feel beyond the present moment and to act at once to attain those results which at the time seem to be the mere embellishments of victory — the luxury of triumph."
Clausewitz quoted by Barbara Tuchmann in The Guns of August. After his victory at Gumbinnen, Russian commander von Rennenkampf allowed a staff officer to rest, but in his uniform. Von Rennenkampf woke the officer an hour later to tell him he could undress and sleep because the Germans were retiring. His failure to pursue the Germans, his German heritage, and his subsequent failures would lead to claims he was a traitor.
