Telegram To General A. B. Burnside.

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.

A. LINCOLN.
