Dec. 18.—The disaster was inaugurated by the shelling of Fredericksburgh. One hundred and forty-seven (147!) guns playing upon a few houses. It was the play of a maddened child, exhibiting in equal proportions, reckless ferocity and egregious stupidity; and it is difficult to find one dyslogistic term which will adequately describe and condemn it.

From what I can already gather of the details of the attack, it may be peremptorily concluded that Burnside, Sumner, and above all, Franklin, are utterly incompetent of a skillful and effective handling of great masses of troops. They attacked by brigades, positions so formidable, that if they could possibly be carried by any exertion of human skill and strength, they could only be carried by large masses impetuously hurled against them. Franklin seems especially to have acted ill in not at once throwing in 10,000 men to be followed rapidly and again and again by 10,000 more. In that wise and only in that wise, he might possibly have broken and turned the enemy, and thrown him on his own centre. It is said that Franklin had 60,000. If so, he could easily have risked some 20,000 in the first onslaught. Sixty thousand! Great God! Why, it is an army in itself, in the hands of a general at all deserving of that name. If those great West Pointers had only even the slightest idea of military history! More battles have been fought and won with 60,000 men, and with fewer still, than with larger numbers, and at Fredericksburgh Franklin's force formed only a wing against an enemy whose whole army could number but little more than 60,000. I want the reports with the full and positive details.

The clear-sighted and warlike Tribune discovered in Burnside high, brilliant, and soldier-like qualities—admirably borne out and illustrated no doubt, by the Fredericksburgh butchery! To the hospital of imbeciles with all such imbeciles!

The Times was manly in its appreciation, and flunkeyed to no one under hand, that is, confidentially and for newspaper publication.

Mr. Seward reveals to the world at large, that, besides his volume of 700 pages, containing the last diplomatic correspondence, he has still an equal number of masterpieces as yet not published. What a dreadful dysentery of despatch-writing the poor man and his still more afflicted readers must labor under.

The Lincoln-Seward policy, has rebuilt the awful Democratic party, which was broken up, prostrated in the dust. Lincoln—Seward—Weed, partially emasculated the Republican party, and may even emasculate the thus far thoroughly virile and devoted patriotism of the people.

A helpless imbecile in the hands of a cunning and selfish and ruthless charlatan, is the sight that daily meets our eyes in Washington.

General Bayard, one of the slaughtered at Fredericksburgh, was a true Bayard of the army, and one of the very few West Pointers free from conceit, that corrosive and terribly prevalent malady of the West Point clique.

Dec. 18.—Senators waking up to their duties, and to the consciousness of their power. These patriots have said to Seward, Averte Sathanas, and overboard he goes, after having done as much evil as only he could do.

The most contradictory rumors are in circulation about Stanton. I cannot find out the truth. I do not believe all that is said, but it is necessary to put the rumors on record. It is said then, that Stanton stands up for the butchers and asses in the army and in his department. I believe that in all this, there is not a single word of truth; but if it were true, then I should say, Stanton is ruined by bad company, and down with him and with them!
