6,000 men and horses." Sheridan relieved Hunter on the 6th, and Grant says in his report, "On the 7th of August, the Middle Department and the Departments of West Virginia, Washington, and the Susquehanna were constituted into the Middle Military division, and Major General Sheridan was assigned to the temporary command of the same. Two divisions of cavalry, commanded by Generals Torbert and Wilson, were sent to Sheridan from the Army of the Potomac. The first reached him at Harper's Ferry on the 11th of August." Before this cavalry was sent to the Valley, there was already a division there commanded by Averill, besides some detachments which belonged to the department of West Virginia. A book containing the official reports of the chief surgeon of the cavalry corps of Sheridan's army, which was subsequently captured at Cedar Creek on the 19th of October, showed that there were present for duty in that corps, during the first week in September, over 11,000 men, and present for duty during the week ending the 17th day of September, 10,100 men The extracts from Grant's report go to confirm this statement, as, if three brigades numbered at least 5,000 men and horses, the two divisions, when the whole of them arrived, with Averill's cavalry, must have numbered over 10,000. I think, therefore, that I can safely estimate Sheridan's cavalry at the battle of Winchester, on the 19th of September, at 10,000. His infantry consisted of the 6th, 19th, and Crook's corps, the latter being composed of the " Army of West Virginia," and one division of the 8th corps. The report of Secretary Stanton shows that there was in the department of which the "Middle Military division" was composed, the following "available force present for duty May 1st, 1864," to wit:
| "Department of Washington | 42,124." |
| "Department of West Virginia | 30,782." |
| "Department of the Susquehanna | 2,970." |
| "Middle Department | 5,627." |
making an aggregate of 81,503; but, as the Federal Secretary of War in the same report says, "In order to repair the losses of the Army of the Potomac, the chief part of the force
