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 time for us to pile on our blows thick and
fast.

Instead of postponing the draft till after the elections, we ought
now to have our ranks full of drafted men; and, at best, if they
come at all, they will reach us when we should be in motion.

I think General Halleck would like to have the honest, candid
opinions of all of us, viz., Grant, McPherson, and Sherman. I have
given mine, and would prefer, of course, that it should coincide
with the others
