in 54,356, gives 6,552, which being deducted, leaves 47,834 as the strength of our infantry when it crossed the Potomac, without deducting my three regiments that were left behind, or the loss sustained in Ewell's corps in the fighting at Winchester and Martinsburg, which amounted to 269.
Add the entire artillery and cavalry without any deduction, and our whole force would be only 61,830.
But the fact was, that the cavalry had had a very severe engagement with that of the enemy near Brandy Station, on the 9th of June, and several other severe engagements near the Blue Ridge before it crossed the Potomac, in which, if Hooker's telegrams are to be accepted as correct, our cavalry was very badly handled, if not almost destroyed; but I take no account of them.
It is well known how rapidly.
cavalry diminishes from loss of horses in action or on the march — in fact, much more than from loss of men when there are no means of replacing the horses, as was the case with our cavalry.
