To Oliver O. Howard

                                                                Executive Mansion,
My dear General Howard                Washington, July 21. 1863.

Your letter of the 18th. is received. I was deeply mortified by the escape of Lee across the Potomac, because the substantial destruction of his army would have ended the war, and because I believed, such destruction was perfectly easy—believed that Gen. Meade and his noble army had expended all the skill, and toil, and blood, up to the ripe harvest, and then let the crop go to waste. Perhaps my mortification was heightened because I had always believed—making my belief a hobby possibly—that the main rebel army going North of the Potomac, could never return, if well attended to; and because I was so greatly flattered in this belief, by the operations at Gettysburg. A few days having passed, I am now profoundly grateful for what was done, without criticism for what was not done. Gen. Meade has my confidence as a brave and skillful officer, and a true man. Yours very truly

A. LINCOLN
