they would either compel the enemy to detach largely for the protection
of his supplies and lines of communication, or he would lose them.
General Sigel was therefore directed to organize all his available force
into two expeditions, to move from Beverly and Charleston, under command
of Generals Ord and Crook, against the East Tennessee and Virginia
Railroad. Subsequently, General Ord having been relieved at his own
request, General Sigel was instructed at his own suggestion, to give up
the expedition by Beverly, and to form two columns, one under General
Crook, on the Kanawha, numbering about ten thousand men, and one on the
Shenandoah, numbering about seven thousand men. The one on the
Shenandoah to assemble between Cumberland and the Shenandoah, and the
infantry and artillery advanced to Cedar Creek with such cavalry as
could be made available at the moment, to threaten the enemy in the
Shenandoah Valley, and advance as far as possible; while General Crook

New River Bridge and the salt-works, at Saltville, Va.

Owing to the weather and bad condition of the roads, operations were

tend more than anything else, unless it were the capture of Lee's army,
to accomplish this desired result in the East. If he failed, it was my
determination, by hard fighting, either to compel Lee to retreat, or to
so cripple him that he could not detach a large force to go north, and

understood, by both Generals Butler and Meade, before starting on the
campaign, that it was my intention to put both their armies south of the
James River, in case of failure to destroy Lee without it.

Before giving General Butler his instructions, I visited him at Fort
Monroe, and in conversation pointed out the apparent importance of
getting possession of Petersburg, and destroying railroad communication
as far south as possible. Believing, however, in the pract
