The captain can usually inflict all the punishment necessary, and the colonel should always.

The field-officers' court is the best form for war, viz., one of the field-officers-the lieutenant-colonel or major -- can examine the case and report his verdict, and the colonel should execute it.

Of course, there are statutory offenses which demand a general court-martial, and these must be ordered by the division or corps commander; but, the presence of one of our regular civilian judge-advocates in an army in the field would be a first-class nuisance, for technical courts always work mischief.
Too many courts-martial in any command are evidence of poor discipline and inefficient officers.
For the rapid transmission of orders in an army covering a large space of ground, the magnetic telegraph is by far the best, though habitually the paper and pencil, with good mounted orderlies, answer every purpose.

I have little faith in the signal-service by flags and torches, though we always used them; because, almost invariably when they were most needed, the view was cut off by intervening trees, or by mists and fogs.

There was one notable instance in my experience, when the signal-flags carried a message.
of vital importance over the heads of Hood's army, which had interposed between me and Allatoona, and had broken the telegraph-wires--as recorded in Chapter XIX.; but the value of the magnetic telegraph in war cannot be exaggerated, as was illustrated by the perfect concert of action between the armies in Virginia and Georgia during 1864.
