reasonable doubt, however, the date under which McClellan incorporated his letter in his official ``report of the operations of Army of the Potomac while under my charge,'' is wrong. McClellan's report, dated at New York, August 4, 1863, prints the letter with numerous details at variance with the original letter in the Lincoln Papers, and in dating his letter February 3, instead of January 31, McClellan either deliberately falsified the record in an effort to support his own case or inadvertently committed an error which had the same effect.
McClellan's report (OR, I, V, 41 ff.) stated that, after receiving Lincoln's Special Order, ``I asked his excellency whether this order was to be regarded as final, or whether I could be permitted to submit in writing my objections to his plan and my reasons for preferring my own. Permission was accorded, and I therefore prepared the letter to the Secretary of War which is given below [under date of February 3 in McClellan's report, but dated January 31 in the original in the Lincoln Papers].
``Before this had been submitted to the President he addressed me the following note: [Lincoln's letter of February 3, but without the enclosure, is here given by McClellan.]
``These questions were substantially answered by the following letter of the same date to the Secretary of War:''
Immediately following, under date of February 3, is the letter of January 31, altered somewhat in minor details in the early paragraphs and marked by the significant omission of important passages toward the end. The letter is too long for reproduction here in its entirety, but because the original contains important passages not in the Official Records, and because of the strange circumstances surrounding the question of date, the heart of McClellan's statement is reproduced below. Portions in italic type are the passages which McClellan omitted in his official report:
``Two bases of operations seem to present themselves for the advance of the Army of the Potomac.---
I. That of Washington---its present position---involving a direct attack upon the enemy's entrenched positions at Centreville, Manassas etc, or else a movement to turn one or both flanks of those positions, or a combination of the two plans.
``The relative force of the two armies will not justify an attack on both flanks.
``An attack on his left flank alone involves a long line of wagon communication & cannot prevent him from collecting for the decisive battle all the detachments now on his extreme right & left.
``Should we attack his right by the line of the Occoquan & a crossing of the Potomac below the Occoquan & near his batteries, we could perhaps prevent the junction of the enemy's extreme right with his centre (we might destroy the former), we would remove the obstructions to the navigation of the Potomac, reduce the length of wagon transportation by establishing new depots at the nearest points of the Potomac, & strike more directly his main railway communication.
``The fords of the Occoquan below the mouth of Bull Run are watched by the rebels, batteries are said to be placed on the heights in rear (concealed by the woods), & the arrangement of his troops is such that he can oppose some considerable resistance to a passage of the stream. Information has just been received to the effect that the enemy are entrenching a line of heights extending from the vicinity of Sangster's (Union Mills?) towards Evansport. Early in Jany. Sprigg's ford was occupied by Genl Rhodes with 3600 men & 8 guns; there are strong reasons for believing that Davis' Ford is occupied.
``These circumstances indicate, or prove, that the enemy anticipate the movement in question & are prepared to resist it. Assuming for the present that this operation is determined upon, it may be well to examine briefly its probable progress.
``In the present state of affairs our columns (for the movement of so large a
