Sept. 25.—The West Point spirit persecutes Sigel with the utmost rage. The West Point spirit seemingly wishes to have Sigel dishonored, defeated, even if the country be thereby destroyed. The Hallecks, &c., keep him in a subordinate position; three days ago his corps was a little over seven thousand, almost no cavalry, and most of the artillery without horses, and he in front.

The more I scrutinize the President's thus called emancipation proclamation, the more cunning and less good will and sincerity I find therein. I hope I am mistaken. But the proclamation is only an act of the military power,—is evoked by military necessity,—and not a civil, social, humane act of justice and equity.

The only good to be derived from this proclamation is, that for the first time the word freedom, and a general comprehension of "emancipation," appear in an official act under the sanction of the formula, and are inaugurated into the official, the constitutional life of the nation. In itself it is therefore a great event for a people so strictly attached to legality and to formulas.

I do not recollect to have read in the history of any great, or even of a small captain,—above all of such a one when between thirty-four and thirty-six years old,—that he followed the army under his command in a travelling carriage and six, when the field of operations extended from fifty to seventy miles. Three cheers for McClellan, for his carriage and six!

HOW THE GREAT CAPTAIN WAS TO CATCH THE WHOLE REBEL ARMY IN MANASSAS, IN FEBRUARY AND MARCH, A. D. 1862.

It was to have been done by a brilliant and unsurpassable stroke of combined strategy, tactics, manœuvres, marches, and swimmings; also on land and water. (O, hear! O, hear!)

As every body knows, the rebels were encamped in the so fearful strongholds of Centreville and Manassas, all the time fooling the commander-in-chief of the federal army in relation to their immense numbers. To attack the rebels in front, or to surround them by the Occoquan and Brentsville, would have been a too—simple operation; by a special, an immense, space-embracing anaconda strategy, the rebel army was to be cut off from the whole of rebeldom, and forced to surrender en masse to the inventor of (the not yet patented, I hope) bloodless victories. To accomplish such an immense result, a fleet of transports was already ordered to be gathered at Annapolis. On them in ten or fifteen days (O, hear!) an army of fifty to sixty thousand, most completely equipped, was to be embarked, plus forty thousand in Washington, all this to sail under the personal command of the general-in-chief, and sail towards Richmond. Richmond taken, the rebel army at Manassas would have been cut off, and obliged to surrender on any terms.

The above splendid conception was, and still is, peddled among the army and among the nation by the admirers of, and the devotees of, anaconda strategy.

The expedition was to land at the mouth of the Tappahannock, a small port, or rather a creek, used for shipping of a small quantity of tobacco. As the port or creek has only some small attempts at wharves, the landing of such an enormous army, with parks of artillery, with cavalry, pontoons, and material for constructing bridges,—the landing would not have been executed in weeks, if in months; but the projector of the plan, perfectly losing the notion of time, calculated for ten days. From that port the flying expedition was to march directly on Richmond through a country having only common field and dirt roads, and this in a season when all roads generally are in an impassable condition, through a country intersected by marshy streams, principal among them the Matapony and the Pamunkey—to march towards Richmond and the Chickahominy marshes. It seems that Chickahominy exercised an attractive, Armida-like charm on the great strategian. An army loaded with such immense trains would have sufficiently destroyed all the roads, and rendered them impassable for itself; and the flying expedition would at once have been transformed into an expedition sticking in the mud, similar to that subsequent in the peninsula. The enemy was in possession of Fredericksburg and of the railroad to Hanover Court House on one flank, and of all the best roads north of and through Chickahominy marshes on the other flank. The flying expedition would have had for base Tappahannock and a dirt road. O strategy! O stuff!

The much-persecuted General McDowell exposed the worse than crudity of the brilliant conception. By doing this, McDowell saved the country, the administration, and the strategian from immense losses and from a nameless shame. It is due to the people that the administration lay before the public the scheme and the refutation. A look on the map of Virginia must convince even the simplest mind of the brilliancy of this conception.
