[211] errors of judgment in the Gettysburg Campaign, and that these contributed not a little to the Confederate failure. Unfortunately, these recent publications of Col. Mosby are of such a character that it is necessary to reopen this painful subject, and to speak as plainly as that writer has done. This is the more necessary because his argument is so plausible, and is stated with so much dialectical skill, that only the very careful reader is likely to detect its fallacies.

Col. Mosby first impeaches the accuracy of both of Gen. Lee's Reports of the Battle of Gettysburg (of July 31st, 1863, and January, 1864), in several important statements made therein, viz.: 1. That Gen. Lee was in ignorance of Hooker's movements until the night of June 28th, 1863, when Gen. Longstreet's scout reported his army approaching South Mountain; 2. That Gen. Lee then, and therefore, changed his plan and ordered his army to concentrate east of South Mountain; 3. That it had been Lee's intention to concentrate at Harrisburg and that he ordered Hill and Longstreet to that place after reaching Chambersburg; 4. That ‘the absence of the Cavalry rendered it impossible to obtain accurate information’ of the movements and position of the Federal Army.

This serious impeachment of Gen. Lee's accuracy in regard to the particulars of his own campaign, is largely based on a letter taken from Gen. Lee's Official Letter Book, and dated at Chambersburg, June 28th, 7:30 A. M., in which Gen. Lee says to Gen. Ewell:

‘I wrote you last night stating that Gen. Hooker was reported to have crossed the Potomac and is advancing by way of Middletown, the head of his column being at that point in Frederick county. I directed you in my letter to move your forces to this point.’

Col. Mosby declares that this letter refutes ‘every word’ of the statements of Gen. Longstreet, Col. Marshall, Gen. Long, Col. Waiter Taylor, Gen. Fitz Lee and Gen. Lee's own report in regard to the compaign in the particulars above named. He further says that Gen. Well's and Gen. Early's reports show that the movement against Harrisburg was arrested on June 27th, and thus agree with the statements of the letter of June 28th, which he quotes.
