Bierce had a word for it

Ambrose Bierce was one of those lucky enough to have fought a long war as an infantryman - and to live to write about it afterwards. He would have made a fine military analyst:
Bragg always retired when we wanted to fight and fought when we most desired peace. [...] By the time that Rosecrans had got his three scattered corps together we were a long way from Chattanooga, with our line of communication with it so exposed that Bragg turned to seize it. Chickamauga was a fight for possession of a road.
Bierce started with Rosecrans in the East (under McClellan) and saw Rosecrans relieved in the West.

The bitterness of "Bitter Bierce" had its foundation in the War of the Rebellion, I think, and just for fun, I've selected a few ACW-themed definitions from his famous Devil's Dictionary. Put down those rose-colored glasses and have a Bierce break.
