During the campaign of forty-three days, from the Rapidan to the James River, the army had to be supplied from an ever-shifting base, by wagons, over narrow roads, through a densely wooded country, with a lack of wharves at each new base from which to conveniently discharge vessels. Too much credit cannot, therefore, be awarded to the quartermaster and commissary departments for the zeal and efficiency displayed by them. Under the general supervision of the chief quartermaster, Brigadier-General R. Ingalls, the trains were made to occupy all the available roads between the army and our water-base, and but little difficulty was experienced in protecting them.
The movement in the Kanawha and Shenandoah valleys, under General Sigel, commenced on the 1st of May. General Crook, who had the immediate command of the Kanawha expedition, divided his forces into two columns, giving one, composed of cavalry, to General Averell. They crossed the mountains by separate routes. Averell struck the Tennessee and Virginia Railroad, near Wytheville, on the 10th, and proceeding to New River and Christiansburg, destroyed the road, several important bridges and depots, including New River Bridge, forming a junction with Crook at Union on the 15th. General Sigel moved up the Shenandoah Valley, met the enemy at New Market on the 15th, and, after a severe engagement, was defeated with heavy loss, and retired behind Cedar Creek. Not regarding the operations of General Sigel as satisfactory, I asked his removal from command, and Major-General Hunter appointed to supersede him. His instructions were embraced in the following dispatches to Major-General H. W. Halleck, chief of staff of the army:
“NEAR SPOTTSYLVANIA COURT HOUSE, VA. “May 20, 1864.

On the whole, therefore, I think it would be better for General Hunter to move in that direction; reach Staunton and Gordonsville or Charlottesville, if he does not meet too much opposition. If he can hold at bay a force equal to his own, he will be doing good service. * * *
