WAR DEPARTMENT, WASHINGTON, July 27, 1863.

MAJOR-GENERAL BURNSIDE, Cincinnati, O.:

Let me explain. In General Grant's first despatch after the fall of Vicksburg, he said, among other things, he would send the Ninth Corps to you. Thinking it would be pleasant to you, I asked the Secretary of War to telegraph you the news. For some reasons never mentioned to us by General Grant, they have not been sent, though we have seen outside intimations that they took part in the expedition against Jackson. General Grant is a copious worker and fighter, but a very meager writer or telegrapher. No doubt he changed his purpose in regard to the Ninth Corps for some sufficient reason, but has forgotten to notify us of it.

TO GENERAL H. W. HALLECK.

EXECUTIVE MANSION, July 29, 1863

MAJOR-GENERAL HALLECK:

Seeing General Meade's despatch of yesterday to yourself causes me to fear that he supposes the Government here is demanding of him to bring on a general engagement with Lee as soon as possible. I am claiming no such thing of him. In fact, my judgment is against it; which judgment, of course, I will yield if yours and his are the contrary. If he could not safely engage Lee at Williamsport, it seems absurd to suppose he can safely engage him now, when he has scarcely more than two thirds of the force he had at Williamsport, while it must be that Lee has been reinforced. True, I desired General Meade to pursue Lee across the Potomac, hoping, as has proved true, that he would thereby clear the Baltimore and Ohio Railroad, and get some advantages by harassing him on his retreat. These being past, I am unwilling he should now get into a general engagement on the impression that we here are pressing him, and I shall be glad for you to so inform him, unless your own judgment is against it.

Yours truly,

A. LINCOLN.
