loss, which, in the absence of his report, I supposed not greater than the average of the other corps. adds to the above the losses of the Confederate cavalry in the fights of Brandy Station (June 9th), and at Aldie, &c., (June 17th to 21st,) before Lee crossed the Potomac, putting the aggregate cavalry loss during the campaign at 1,100, and thus brings up the Confederate loss to the neighborhood of 24,000 men. But with what propriety this addition should be made to the losses at Gettysburg I am at a loss to perceive. The two cavalry fights mentioned cost the Federals, according to Gen. Gregg, commanding one of the Federal cavalry divisions (see Philadelphia Times, March 31st, 1877), about 1,000 men, and between the dates of these combats Milroy was overthrown at Winchester, with a loss of over 4,500 men. These Federal losses are of course not included in Gen. Meade's aggregate of 23,186 lost. has omitted Ewell's loss at Winchester, June 15th, from his aggregate of Confederate losses. He should have omitted Stuart's also, as otherwise his statement is confusing and inaccurate.
I have carefully re-examined Dr. Bates' statement, as well as the other data at hand, in regard to the strength of the respective armies, but do not find any reason to doubt the general correctness of the estimates, which thinks erroneous. As he does not give the ground for his opinion, I do not know on what he bases it. His criticism on the number and strength of the regiments, even if correct, would give no support to Dr. Bates' conclusions. As to the number of the regiments, I distinctly adopted Dr. Bates' roster. He gives 163 (not 167 as has it) as the number of Confederate infantry regiments present. His roster is incorrect in several particulars. For instance, he enumerates the First, Seventh and Fourteenth S. C. regiments twice (page 308); gives eight regiments to O'Neal's brigade, which only contained five; and omits Garnett's brigade, of Pickett's division, altogether. (I will send you a correct roster as soon as I can get at the data.) But these and some other errors do not destroy its general cor-
