Major McClellan, Stuart's Adjutant-General, says that there was, at the beginning of the campaign, less than 6,000 for duty in the three brigades of cavalry that were with Stuart when he crossed the Potomac, there being about 4,500 in the two brigades of Robertson and Jones. He further says that the losses in action in these three brigades, which bore the brunt of the battle of Fleetwood, and the cavalry fights near the Blue Ridge, and from hard service and deficiency of forage, had reduced them to less than 4,000 when he crossed the Potomac; and he thinks to about 3,500. General Fitz. Lee thinks they were under 4,000 strong at the battle. This loss was not unreasonable, as will be seen when we come to notice that in the Federal cavalry. Jenkins' brigade, which was not embraced in the returns of May 31st, was about 1,600 strong before it crossed the Potomac, and White's battalion, which belonged to Jones' brigade, did not exceed 200. 6,000, therefore, will cover all the cavalry we had available for the battle. The artillery numbered 4,702 on the 31st of May, and some of it was very evidently left in Virginia with Corse's brigade, as the return for July 20th shows more present for duty in the artillery at that date than on the 31st of May. Some therefore must have rejoined the army by the former date, and very probably some that had been left with Jenkins' brigade near Suffolk had come back. We had 252 pieces with the infantry, as shown by a statement furnished me by General Pendleton, and allowing 15 men to a piece, which would be a superabundance, would give 3,780 men. Add 220 for the officers, giving nearly one to a piece, and we have 4,000, which certainly covered the artillery force with the infantry. There were 16 pieces of horse artillery with the cavalry, the men for which were returned with the cavalry, and as part thereof. They are included in the 6,000 allowed for that arm.
We had therefore not exceeding 60,000 men of all arms for duty at Gettysburg. In this estimate I do not include the cavalry brigades of Robertson, Jones and Imboden, which did not arrive in time to take part in the battle, and should not be counted as part of the force available for it. If they are to be counted as a part of our force at Gettysburg, then the 8,000 men under French at Frederick, which were employed in protecting Meade's com-
