"….In pushing up the Shenandoah Valley, as it is expected you will have to go first or last, it is desirable that nothing should be left to invite the enemy to return. Take all provisions, forage, and stock wanted for the use of your command. Such as cannot be consumed, destroy. It is not desirable that buildings should be destroyed—they should, rather, be protected; but the people should be informed that so long as an army can subsist among them, recurrences of these raids must be expected, and we are determined to stop them at all hazards…." [Grant's letter of instructions.]
"HEADQUARTERS MIDDLE MILITARY DIVISION,
"Cedar Creek, Va., August 16, 1864.
"GENERAL: In compliance with instructions of the Lieutenant-General commanding, you will make the necessary arrangements and give the necessary orders for the destruction of the wheat and hay south of a line from Millwood to Winchester and Petticoat Gap. You will seize all mules, horses, and cattle that may be useful to our army. Loyal citizens can bring in their claims against the Government for this necessary destruction. No houses will be burned, and officers in charge of this delicate but necessary duty must inform the people that the object is to make this valley untenable for the raiding parties of the rebel army.
"Very respectfully,
"P. H. SHERIDAN,
"Major-General Commanding.
"BRIGADIER-GENERAL A. T. A. TORBERT,
"Chief of Cavalry, Middle Military Division."
During his visit to General Hunter at the Monocacy, General Grant had not only decided to retain in the Shenandoah Valley a large force sufficient to defeat Early's army or drive it back to Lee, but he had furthermore determined to make that sections by the destruction of its supplies, untenable for continued occupancy by the Confederates. This would cut off one of Lee's main-stays in the way of subsistence, and at the same time diminish the number of recruits and conscripts he received; the valley district while under his control not only supplying Lee with an abundance of food, but also furnishing him many men for his regular and irregular forces. Grant's instructions to destroy the valley began with the letter of August 5 to Hunter, which was turned over to me, and this was followed at intervals by more specific directions, all showing the earnestness of his purpose.
"CITY POINT, Va., Aug. 16—3:30 P. M., 1864.
"MAJOR-GENERAL SHERIDAN, Winchester, Va.:
"If you can possibly spare a division of cavalry, send them through Loudoun County to destroy and carry off the crops, animals, negroes, and all men under fifty years of age capable of bearing arms. In this way you will get many of Mosby's men. All male citizens under fifty can fairly be held as prisoners of war, not as citizen prisoners. If not already soldiers, they will be made so the moment the rebel army gets hold of them.
"U. S. GRANT, Lieutenant-General."
