Russia is the strength of oppression. Her force in the background emboldens every petty tyrant and makes every oppressed nation despond: not because she is so very powerful, but because all foresee distinctly that she will act unshrinkingly in the tyrant's favour so soon as he needs it. We fought, beat, crushed the Austrian emperor, of course not without sacrifice. You know that your own brave Duquesne Greys lost in one action more than half their men. Now, if after a victory gained at such a price, Russia steps in with a fresh force, well provided with every means of war, though that force be not such as one could not resist, it is formidable as a rearguard, falling fresh upon a nation exhausted with its very victories. Suppose that at the close of your own Mexican victories, you had to meet a fresh host of 100,000 well-disciplined men, what would have been the fate of your gallant army, which entered the city of Montezuma?

That is the key of Russian preponderance. But consider the consequences of our defeat. Austria was restored,—not to its independent position—that is lost forever; but, to the position of a tyrant at home, obedient to the wink of his master abroad. Relying on the precedent established by Russia,—Naples, Spain, and degraded France interfered in ROME. After this, Austria and Prussia quarrelled for German supremacy, but before they drew the sword, went to the Czar for permission. The Czar at Warsaw replied: "I forbid you to quarrel. Reconstruct the German confederacy of 1815 and add to it no constitutional element. Send your two armies to HESSE CASSEL; crush the people who there resist by law the Grand Duke's attempt to overthrow the sworn Constitution. As to SCHLESWIG HOLSTEIN, I want to have it reserved to Denmark, as a satrapy for my servant and nephew. The German confederacy having dared to countenance its rebellion, shall be punished by having to request Austria to send an army against it." So ordered the Czar, and so it was done. And after it was done, the Czar ordered the withdrawal of the pageant of a Constitution, which in the hour of need the Emperor of Austria had promised to his empire. It was withdrawn. When thus every popular movement was crushed, every shadow of freedom withdrawn, the scaffolds of Hungary and Italy saturated with blood, the prisons filled with martyrs, the exiles driven from every asylum in the European continent, and Germany reduced to a condition worse than when the Unholy Alliance was at the full tide,—then the Czar wrote an autograph letter to Louis Napoleon, the perjured President of France, assuring him of his imperial grace and benevolent support, if he would strike a deathblow to the French Republic. And Louis Napoleon struck the blow.

Such are the results of the overwhelming preponderance of Russia, imposed upon Europe by its interference in Hungary. Suppose now that I succeed in my sacred mission,—sacred, because it is the cause of law and of all the oppressed;—suppose Russian interference checked; then Hungary will crush the tottering Austrian dynasty: Italy, delivered from foreign dominion, will sportively dispose of its petty tyrants. The nation of Austria will become free, and a valuable ingredient in German liberty. At the result of a glorious struggle in Hungary, burning shame will mount to the cheek of the French, and Louis Napoleon will be shaken off.

Let interference by the combination of despots be checked, let nations become masters of their own fate,—and rely upon the magic power of your glorious example. Republican institutions will spread as the light of the sun. Yes, gentlemen. It is not for one country that I ask your support. My ground is as broad as the world; for it is the ground of eternal principles, common to all humanity. No man, on the pretext that his heart is with some other nation,—German, Italian, Pole, French; no man, on the pretext that he is a Universal philanthropist, ought to refuse his sympathies to Hungary; for its cause happens in this crisis to comprise the rest. If I were a Pole, a German, or an Italian, egotistically patriotic, I could not serve my country better than by attacking Russia, the only substantial enemy.

What would the petty princes of Germany have been in 1848 without Prussia? and what was Prussia, when her capital was in the hands of the people, but for the certainty of the Czar's support? What were the petty despots of Italy without Austria? and what was Austria, when her armies, driven from the soil of Hungary in a series of pitched battles, were so demoralized, that nothing but the treacherous disobedience of a general prevented our brave militia from extinguishing in Vienna and Olmutz the decrepit absolutism of the Hapsburgs? What hindered me from afterwards crushing it? The intervention of Russian despotism,—always the primal cause of evil.

Absolutism has understood and declared, that its repose is impossible, whilst a free press and free institutions exist any where. Formerly the absolutists adhered to the principle of "legitimacy," or, the Divine right of an hereditary dynasty; and provided this false principle was respected, they did not object to the development of constitutions which preserved attachment to monarchies. But now they have thrown away their own principle of dynastical legitimacy, and have no rule but to oppress freedom everywhere. Whoever will join them in that work is welcome, though he be a usurper. Thus it came to pass, that Henry of Bourbon was rejected by the despots, while Louis Napoleon has received from the Czar an autograph letter of approval, and from Austria complimentary gifts. Will the United States remain inactive, while free institutions are systematically extinguished? Can they look on indifferently, because seventy years ago it was a wise doctrine, appropriate to their childhood, not to care about European politics?

It is publicly reported, that Russia has decided to absorb Turkey; and means to grant Italy to Austria; Belgium, and the Rhenish provinces to France; and the rest of Germany to Prussia. The Czar, acting like the Persian Kings of old when they sent garments of honour to their satraps, flings in the addition of a few provinces of kingdoms to their satrapies.

And oh! Almighty father of humanity! is there no power on earth to stop this execrable annihilation of human and national rights, of freedom and independence?—though there is a Republic powerful enough to do so—a Republic founded upon the very principles which the despotic powers have put under an inexorable ban!

Gentlemen, I have dwelt perhaps too long on the condition of Europe; but it was necessary to show that though there be no Russian eagles, painted over the public offices in Germany, Italy, France, still the Russian frontier is really extended to the Atlantic.

People of free America, beware, ere it be too late! Hurriedly and by sudden violence, all civil and religious liberty must, for the repose of absolutism, be trampled out of Europe; and by more deliberate perpetration, by diplomacy, persuasion, and gold, the way must be prepared to trample it out elsewhere by ulterior violence.
