incoln had read it carefully, and had instructed him to obtain my
consent to have it published. At the time, I preferred not to be
drawn into any newspaper controversy, and so wrote to General
Halleck; and the above letter has never been, to my knowledge,
published; though Mr. Lincoln more than once referred to it with
marks of approval.

HEADQUARTERS FIFTEENTH ARMY CORPS
CAMP ON BIG BLACK, September 17, 1863

Brigadier-General J. A. RAWLINS,
Acting Assistant Adjutant-General, Vicksburg.

DEAR GENERAL: I inclose for your perusal, and for you to read to
General Grant such parts as you deem interesting, letters received
by me from Prof. Mahan and General Halleck, with my answers. After
you have read my answer to General Halleck, I beg you to inclose it
to its address, and return me the others.

I think Prof. Mahan's very marked encomium upon the campaign of
Vicksburg is so flattering to General Grant, that you may offer to
let him keep the letter, if he values such a testimonial. I have
never written a word to General Halleck since my report of last
December, after the affair at Chickasaw, except a short letter a
few days ago, thanking him for the kind manner of his transmitting
to me the appointment of brigadier-general. I know that in
Washington I am incomprehensible, because at the outset of the war
I would not go it blind and rush headlong into a war unprepared and
with an utter ignorance of its extent and purpose. I was then
construed unsound; and now that I insist on war pure and simple,
with no admixture of civil compromises, I am supposed vindictive.
You remember what Polonius said to his son Laertes: "Beware of
entrance to a quarrel; but, being in, bear it, that the opposed may
beware of thee." What is true of the single man, is equally true
of a nation. Our leaders seemed at first to thirst for the
quarrel, willing, even anxious, to array against us all possible
elements of opposition; and now, being in, they would hasten to
quit long before the "opposed" has received that lesson which he
needs. I would make this war as severe as possible, and show no
symptoms of tiring till the South begs for mercy; indeed, I know,
and you know, that the end would be reached quicker by such a
course than by any seeming yielding on our part. I don't want our
Government to be bothered by patching up local governments, or by
trying to reconcile any class of men. The South has done her
worst, and now is the tim
