|Jackson saves Early's brigade while Sigel piddles|
—Gen. Halleck sends Maj. Gen. Horatio G. Wright to Kentucky to take command of the Department and troops there, and prepare to defend against the anticipated Confederate invasion.
—Pres. Abraham Lincoln’s Letter to Horace Greeley is published on this date in the New York Tribune. (Ironically, while Lincoln seems to suggest a cynical indifference to the fate of the slaves, at the time he writes this letter he has the Emancipation Proclamation sitting in his desk---which he has already shared with his Cabinet earlier in the summer---and he has apparently already decided to use it, just as soon as the Federal armies can come up with a convincing victory.) But these lines from his letter become some of the most oft-quoted words from the War:
But many who read the letter as indifference to slavery miss the import of his concise closing thought:
—George Michael Neese, of the Confederate artillery, recounts his battery’s experience as they move to flank Pope’s army, and the clashes between Stuart’s cavalry (and artillery) with the Yankees:
—Sarah Morgan writes in her journal of the news that Baton Rouge has been sacked and looted by the Yankee soldiers:
—Surgeon Alfred L. Castleman of the Army of the Potomac writes with disgust in his journal about the retreat and about the petty jealousies amongst the generals:
The jealousy of our commanders towards General Pope is so intense, that if I mistake not, it will, on the first occasion, "crop out" in such form as shall damage our cause more than all the cowardice, incompetency and drunkenness which have so far disgraced our campaigns. General Pope’s advance proclamation was construed into a strike at McClellan’s manner of warfare, and, notwithstanding that the former has publicly disclaimed any such intention, there has existed an intense bitterness between the friends of the two ever since, nor is it lessened by the subsequent failures of McClellan and the reported successes of Pope. It is interesting, but saddening, to witness the brightening of countenances among some of the staffs of the army of the Potomac, whilst listening to or reading the reports of the repulses of General Pope. Stonewall Jackson’s official report of his "splendid victory" over our army of Virginia, has caused more joy amongst them than would the wining of a splendid success by McClellan himself. Our Generals seem to have forgotten that this is the people’s war, not their’s; that it is waged at the cost of the treasure and of the best blood of the nation, not to promote the ambitious views of individuals or parties but to protect the people’s right to Government. I begin to fear that patriotism as an element of this army is the exception, not a rule.
