April 21.—The American people never will and never can know and realize the whole immensity of McClellan's treasonable incapacity, and to what extent all subsequent disasters have their roots in the inactivity of McClellan during 1861-62. Whatever may be the official reports, or private investigations, chronicles, confessions, memoirs, all the facts will never be known. Never will it be known how almost from the day when he was intrusted with the command, McClellan was without any settled plans, always hesitating, irresolute; how almost hourly he (deliberately or not, I will not decide) stuffed Mr. Lincoln with lies, and did the same to others members of the Cabinet. The evidences thereof are scattered in all directions, and it is impossible to gather them all. Mr Lincoln could testify—if he would. Almost every day I learn some such fact, but I could not gather and record them all. Seward mostly sided with McClellan, and so did Blair, par nobile fratrum.

Few, if any, detailed reports of the campaigns and battles fought by McClellan have been sent by him to the President or to the War Department. Such reports ought to be made immediately; so it is done in every well regulated government. It is the duty of the staff of the army to prepare the like reports. But McClellan did in his own way, and his reports, if ever he sends them, would only be disquisitions elaborated ex post, and even apart from their truthfulness—null.

All kinds of lies against Stanton have been elaborated by McClellan and his partisans, and circulated in the public. The truth is, that when Stanton became McClellan's superior, Stanton tried in every friendly and devoted way to awake McClellan to the sense of honor and duty, to make him fight the enemy, and not dodge the fight under false pretenses. Stanton implored McClellan to get ready, and not to evade from day to day; and only when utterly disappointed by McClellan's hesitation and untruthfulness, Stanton, so to say, in despair, forced McClellan to action. Stanton was a friend of McClellan, but sacrificed friendship to the sacred duty of a patriot.

April 21.—England plays as false in Europe as she does here. England makes a noise about Poland, and after a few speeches will give up Poland. More than forty years of experience satisfied me about England's political honesty. In 1831, Englishmen made speeches, the Russian fought and finally overpowered us. England hates Russia as it hates this country, and fears them both. I hope a time will come when America and Russia joining hands will throttle that perfidious England. Were only Russia represented here in her tendencies, convictions and aspirations! What a brilliant, elevated, dominating position could have been that of a Russian diplomat here, during this civil war. England and France would have been always in his ante-chambre.

April 21.—Letter-writing is the fashion of the day. Halleck treads into Seward's footsteps or shoes. Halleck thunders to Union leagues; to meetings; it reads splendidly, had only Halleck not contributed to increase the "perils" of the country. Letter-writing is to atone for deadly blunders. The same with Seward as with Halleck. If Halleck would not have been fooled by Beauregard, if Halleck had taken Corinth instead of approaching the city by parallels distant five miles; the "peril" would no longer exist.

April 21.—Foreign and domestic papers herald that the honorable Sanford, United States Minister to Belgium, and residing in Brussels, has given a great and highly admired diplomatic dinner, etc., etc. I hope the Sewing machine was in honor and exposed as a surtout on the banquet's table, and that only the guano-claim successfully recovered from Venezuela, and other equally innocent pickings paid the piper. Vive la bagatelle, and Seward's alter ego at the European courts.

April 22.—I so often meet men pushed into the background of affairs; men young, intelligent, active, clear-sighted, in one word, fitted out with all mental and intellectual requisites for commanders, leaders, pilots and helmsmen of every kind; and nevertheless twenty times a day I hear repeated the question: "Whom shall we put? we have no men."—It is wonderful that such men cannot cut their way through the apathy of public opinion, which seems to prefer old hacks for dragging a steam engine instead of putting to it good, energetic engineers, and let the steam work. Young men! young men, it is likewise your fault; you ought to assert yourselves; you ought to act, and push the fogies aside, instead of subsiding into useless criticism, and useless consideration for experienced narrow-mindedness, for ignorance or for helplessness. In times as trying as ours are, men and not counterfeits are needed.

April 22.—In Europe, they wonder at our manner of carrying on the war, at our General-in-Chief, who, in the eyes and the judgment of European generals, acts without a plan and without an ensemble; they wonder at the groping and shy general policy, and nevertheless a policy full of contradictions. The Europeans thus astonished are true friends of the North, of the emancipation, and are competent judges.

April 22.—I hear that Hooker intends to make a kind of feint against Lee. Feints are old, silly tricks, almost impossible with large armies, and therefore very seldom feints are successful. Lee is not to be caught in this way, and the less so as he has as many spies as inhabitants, in, and around Hooker's camp. To cross the river on a well selected point, and, Hooker-like, attack the surprised enemy is the thing.

April 22.—"Loyalty, loyalty," resounds in speeches, is re-echoed in letters, in newspapers. Well, Loyalty, but to whom? I hope not to the person of any president, but to the ever-living principle of human liberty. Next eureka is, "the administration must be sustained." Of course, but not because it intrinsically deserves it, but because no better one can be had, and no radical change can be effected.
