On the 1st of October the President visited General McClellan at his headquarters, and made himself acquainted with the condition of the army. Five days later he ordered McClellan to {192} "cross the Potomac, and give battle to the enemy, or drive him south." The despatch added, "Your army must move now, while the roads are good. If you cross the river between the enemy and Washington, and cover the latter by your operation, you can be reinforced with thirty thousand men." Nevertheless, McClellan did not stir. Instead of obeying the order, he inquired what sort of troops they were that would be sent to him, and how many tents he could have, and said his army could not move without fresh supplies of shoes and clothing. While he was thus paltering, the Confederate General Stuart, who had ridden around his army on the peninsula, with a small body of cavalry rode entirely around it again, eluding all efforts for his capture. On the 13th the President wrote a long, friendly letter to General McClellan, in which he gave him much excellent advice that he, as a trained soldier, ought not to have needed. A sentence or two will suggest the drift of it: "Are you not over-cautious when you assume that you cannot do what the enemy is constantly doing? ... In coming to us, he [the enemy] tenders us an advantage which we should not waive. We should not so operate as to merely drive him away.... It is all easy if our troops march as well as the enemy, and it is unmanly to say they cannot do it." The letter had outlined a plan of campaign, but it closed with the words, characteristic of Lincoln's modesty in military matters, "This letter is in no sense an order." Twelve days more of fine weather were frittered away in renewed complaints, and such inquiries as whether the President wished him to move at once or wait for fresh horses, for the general said his horses were fatigued and had sore tongue. Here the President began to show some impatience, and wrote: "Will you pardon me for asking what the horses of your army have done since the battle of Antietam that fatigues anything?" The general replied that they had been scouting, picketing, and making reconnoissances, and that the President had done injustice to the cavalry. Whereupon Mr. Lincoln wrote again: "Most certainly I intend no injustice to any, and if I have done any I deeply regret it. To be told, after more than five weeks' total inaction of the army, and during which period we had sent to that army every fresh horse we possibly could, amounting in the whole to 7,918, that the cavalry horses were too much fatigued to move, presented a very cheerless, almost hopeless, prospect for the future, and it may have forced something of impatience into my despatches." That day, October 26, McClellan began to cross the Potomac; but it was ten days (partly owing to heavy rains) before his army was all on the south side of the river, and meanwhile he had
