your communication with Richmond within the next twenty-four hours? You dread his going into Pennsylvania, but if he does so in full force, he gives up his communications to you absolutely, and you have nothing to do but to follow and ruin him. If he does so with less than full force, fall upon and beat what is left behind all the easier. Exclusive of the water-line, you are now nearer Richmond than the enemy is by the route that you can and be must take. Why can you not reach therefore before him, unless you admit that he is more than your equal on a march? His route is the arc of a circle, while yours is the chord. The roads are as good on yours as on his. You know I desired, but did not order, you to cross the Potomac below instead of above the Shenandoah and Blue Ridge. My idea was that this would at once menace the enemy's communications, which I would seize if he would permit.
If he should move northward I would follow him closely, holding his communications. If he should prevent our seizing his communications and move toward Richmond, I would press closely to him; fight him, if a favorable opportunity should present, and at least try to beat him to Richmond on the inside track. I say "try;" if we never try we shall never succeed. If he makes a stand at Winchester, moving neither north nor south, I would fight him there, on the idea that if we cannot beat him when he bears the wastage of coming to us, we never can when we bear wastage of going to him. This proposition is a simple truth, and is too important to be lost sight of for a moment. In coming to us he tenders us an advantage which we should not waive. We should not so operate as to merely drive him away. As we must beat him somewhere of fail finally, we can do it, if at all, easier near to us than far away. If we cannot beat the enemy where he now, is we never can he again being within the entrenchments of Richmond.
Recurring to the idea of going to Richmond on the inside track, the facility of supplying from the side away from the enemy is remarkable, as it were, by the different spokes of a wheel extending form the hub toward the rim, and this,whether you move directly by the chord or on the inside arc, hugging the Blue Ridge more closely. The chordline, as you see, carries you by Aldie, hay Market, and Fredericksburg; and you see how turnpikes, railroads, and finally the Potomac, by Aquia Creek, meet you at all points from Washington; the same, only the lines lengthened a little, if you press closer to the Blue Ridge part of the way.
The gaps the Blue Ridge I understand to be about the following distances from Harper's Ferry, to wit: Vestal's, 5 miles; Gregory's 13; Snicker's, 18; Ashby's, 28; Manassas, 38; Chester, 45; and Thornton's, 53. I should think it preferable to take the route nearest the enemy, disabling him to make an important move without your knowledge, and compelling him to keep his forces together for dread of you. The gaps would enable you to attack if you should wish. For a great part of the way you would be practically between the enemy and both Washington and Richmond, enabling us to spare you the greatest number of troops from here. When at length running for Richmond ahead of him enables him to move this way, if he does so, turn and attack him in the rear. But i think he should be engaged long before such point is reached. It is all easy if our troops march as well as the enemy, and it is unmanly to say they cannot do it. This letter is in no sense an order.
