I will quote also from Judge Thurman himself. In a speech lecturing one of his colleagues, who thought the Mexican war was unnecessary, he says:

"It is a strange way to support one's country, right or wrong, to declare after war has begun, when it exists both in law and in fact, that the war is aggressive, unholy, unrighteous, and damnable on the part of the government of that country, and on that government rests its responsibility and its wrongfulness. It is a strange way to support one's country right or wrong in a war, to tax one's imagination to the utmost to depict the disastrous consequences of the contest; to dwell on what it has already cost and what it will cost in future; to depict her troops prostrated by disease and dying with pestilence; in a word, to destroy, as far as possible, the moral force of the government in the struggle, and hold it up to its own people and the world as the aggressor that merits their condemnation. It was for this that I arraigned my colleague, and that I intend to arraign him. It was because his remarks, as far as they could have any influence, were evidently calculated to depress the spirits of his own countrymen, to lessen the moral force of his own government, and to inspire with confidence and hope the enemies of his country."

"What a singular mode it was of supporting her in a war to bring against the war nearly all the charges that were brought by the peace party Federalists against the last war, to denounce it as an unrighteous, unholy, and damnable war; to hold up our government to the eyes of the world as the aggressors in the conflict; to charge it with motives of conquest and aggrandizement; to parade and portray in the darkest colors all the horrors of war; to dwell upon its cost and depict its calamities."

Now, that was the doctrine of Judge Thurman as to the duties of citizens in time of war--in time of such a war as the Mexican war even, in which no vital interest of the country could by possibility suffer. Judge Thurman says that General Hayes, in his speech, has a great many slips cut from the newspapers, and that he must have had some sewing society of old ladies to cut out the slips for him. I don't know how he found that out. I never told it, and you know the ladies never tell secrets that are confided to them. I hold in my hand a speech of Judge Thurman, from which I have read extracts, and I find that he has in it slips cut from more than twenty different prints, sermons, newspapers, old speeches, and pamphlets, to show how, in the war of 1812, certain Federalists uttered unpatriotic sentiments. I presume he must have acquired his slips on that day in the way he says I acquired mine now.
