The calumny so often repeated, so urgently insisted upon, that the aim of the Polish insurrection was inconsistent, foolish, and wicked, might not perhaps astonish the reader more than the report of the want of zeal and faith in the convictions of the Poles, a fact first revealed to the world in 'Tardy Truths.' This warning with regard to the true character of the struggle on the shores of the Vistula might prove of service in aiding the discrimination of the American people, and be useful in confusing the judgment of the liberal men and newspapers, which, whether in Germany, Belgium, France, or England, are not too much inclined to favor the cause of Polish independence; nay, it would spare France the useless demonstration in the Chambers, made in consequence of the speech of November 5th. The late efforts of the Poles are also shown to have been inspired and incited by, and carried on for the benefit of, the Catholic clergy, stimulated by fanaticism against the liberal, civilizing, enlightened, Rosso-Greek Church, a view which might and has proved very useful to modern lecturers and letter writers. The warning therein given might also serve to degrade the Polish revolution to the level of some of the slave-holders' rebellion. Let us reflect but for one single moment on the parallel attempted to be drawn, particularly in the New York papers, after the unfortunate Mexican imbroglio and subsequent visit of the Russian fleet, between things so utterly unlike. The Poles fought for everything most dear to the heart of man, for every right which he can justly claim, for independence, national existence, the right to use his own language, for the integrity of his country;--the States of the South had all these in full possession, nay, even the right to pass the law binding the North. These things might be shown to be essentially dissimilar in _every_ respect, but this short statement is deemed sufficient to show the futility of the comparison.
