To General J. C. Fremont.

Washington; June 13. 1862

MAJOR-GENERAL FREMONT:

We cannot afford to keep your force and Banks's and McDowell's engaged in keeping Jackson south of Strasburg and Front Royal. You fought Jackson alone and worsted him. He can have no substantial reinforcements so long as a battle is pending at Richmond. Surely you and Banks in supporting distance are capable of keeping him from returning to Winchester. But if Sigel be sent forward to you, and McDowell (as he must) be put to other work, Jackson will break through at Front Royal again. He is already on the right side of the Shenandoah to do it, and on the wrong side of it to attack you. The orders already sent you and Banks place you and him in the proper positions for the work assigned you. Jackson cannot move his whole force on either of you before the other can learn of it and go to his assistance. He cannot divide his force, sending part against each of you, because he will be too weak for either. Please do as I directed in the order of the 8th and my despatch of yesterday, the 12th, and neither you nor Banks will be overwhelmed by Jackson. By proper scout lookouts, and beacons of smoke by day and fires by night you can always have timely notice of the enemy's approach. I know not as to you, but by some this has been too much neglected.

A. LINCOLN. TO GENERAL J. C. FREMONT

WAR DEPARTMENT, WASHINGTON CITY, D. C., June 15, 1862.

MAJOR-GENERAL FREMONT:

MY DEAR SIR:—Your letter of the 12th by Colonel Zagonyi is just received. In answer to the principal part of it, I repeat the substance of an order of the 8th and one or two telegraphic despatches sent you since.

We have no definite power of sending reinforcements; so that we are compelled rather to consider the proper disposal of the forces we have than of those we could wish to have. We may be able to send you some dribs by degrees, but I do not believe we can do more. As you alone beat Jackson last Sunday, I argue that you are stronger than he is to-day, unless he has been reinforced; and that he cannot have been materially reinforced, because such reinforcement could only have come from Richmond, and he is much more likely to go to Richmond than Richmond is to come to him. Neither is very likely. I think Jackson's game—his assigned work—now is to magnify the accounts of his numbers and reports of his movements, and thus by constant alarms keep three or four times as many of our troops away from Richmond as his own force amounts to. Thus he helps his friends at Richmond three or four times as much as if he were there. Our game is not to allow this. Accordingly, by the order of the 8th, I directed you to halt at Harrisonburg, rest your force, and get it well in hand, the objects being to guard against Jackson's returning by the same route to the upper Potomac over which you have just driven him out, and at the same time give some protection against a raid into West Virginia.

Already I have given you discretion to occupy Mount Jackson instead, if, on full consideration, you think best. I do not believe Jackson will attack you, but certainly he cannot attack you by surprise; and if he comes upon you in superior force, you have but to notify us, fall back cautiously, and Banks will join you in due time. But while we know not whether Jackson will move at all, or by what route, we cannot safely put you and Banks both on the Strasburg line, and leave no force on the Front Royal line—the very line upon which he prosecuted his late raid. The true policy is to place one of you on one line and the other on the other in such positions that you can unite once you actually find Jackson moving upon it. And this is precisely what we are doing. This protects that part of our frontier, so to speak, and liberates McDowell to go to the assistance of McClellan. I have arranged this, and am very unwilling to have it deranged. While you have only asked for Sigel, I have spoken only of Banks, and this because Sigel's force is now the principal part of Bank's force.

About transferring General Schenck's commands, the purchase of supplies, and the promotion and appointment of officers, mentioned in your letter, I will consult with the Secretary of War to-morrow.

Yours truly,

A. LINCOLN.
