Prior to the 23d March, 1776, the legislature of Massachusetts authorized the issuing of letters of marque to privateers upon the ocean, and when my learned friend, Mr. Lord, in his remarks so clear and convincing, called attention to the lawfulness of privateering, my brother Evarts attempted to qualify it by designating the granting of letters of marque as reluctantly tolerated, and as if no such practice as despoiling commerce should be permitted even in a state of war. I will not again read from Mr. Marcy's letter, but I will say here that the position he took gratified the heart of the whole American people. He said in substance, If you, England and France, have the right to despoil commerce with armed national vessels we have a right to adopt such means of protection and retaliation as we possess. We do not propose, if you make war upon us, or we find it necessary to make war upon you, that we, with a poor, miserable fleet, shall not be at liberty to send out privateers, but yield to you, who may come with your steel-clad vessels and powerful armament to practice upon us any amount of devastation. No. We never had a navy strong enough to place us in such a position as that with regard to foreign powers. Look at it. Do you think that France or England has any feeling of friendship towards this country as a nation? I do not speak of the people of these countries, but of the cabinets and governments. No. Nations are selfish. Nearly all the laws of nations are founded on interest. Nations conduct their political affairs on that basis. They never receive laws from one another—not even against crime. And when you want to obtain back from another country a man who has committed depredations against society, you do it only by virtue of a treaty, and from no love or affection to the country demanding it. And if this war continues much longer, I, for one, entertain the most profound apprehension that both these powers, France and England, will combine to break the blockade if they do not enter upon more aggressive measures. If they for a moment find it their interest to do so, they will, and no power, moral or physical, can prevent them. I say, then, the right of revolution is a right to be exercised, not according to what the Government revolted against may think, but according to the necessities or the belief of the people revolting. If you belonged to a State which was in any way deprived of its rights, the moment that oppression began resistance became a duty. A slave does not ask his master when he is to have his freedom, but he strikes for it at the proper opportunity. A man threatened with death at the hands of another, does not stop to ask whether he has a right to slay his assailant in self-defence. If self-preservation is the first law of individuals, so also is it of masses and of nations. Therefore, when the American Colonies made up their minds to achieve independence, whether their reasons were sufficient or not, they did not consent to have the question decided by Great Britain, but at once decided it for themselves. Very early in our history, in 1778, France recognized the American Government. England, as you know, complained, and the French Government sent back an answer saying, Yes, we have formed a treaty with this new Government; we have recognized it, and you have no right to complain; for you remember, England, said France, that during the reign of Elizabeth, when the Netherlands revolted against Spain, you, in the first place, negotiated secret treaties with the revolutionists, and then recognized them; but, when Spain complained of this, you said to Spain—The reasons which justify the Netherlands in their revolt entitle them to our support. Was success necessary? Was the doctrine of our opponents correct, that, though people may be in absolute revolt against the parent Government, with an army in the field, and in exclusive possession of the territories they occupy, yet they have no right to be recognized by the law of nations, and are not entitled to the humanities that accompany the conditions of a war between foreign powers? Is success necessary? Why was it not necessary in the case of the Colonies when recognized by France? Why not necessary in the case of the Netherlands when recognized by England? Never has been put forward such a doctrine for adjudication since the days of Ogden and Smith, tried in this city in 1806. That was a period when we were in profound peace with all the world. Our new country was proceeding on the march towards that greatness which every one hoped would be as perpetual as it was progressive. We had invited to our shores not only the oppressed of other lands, but all they could yield us of genius, eloquence, industry and wisdom. Among others who came to assist our progress and adorn our history was that eminent lawyer and patriot—that good and pure man whose monument stands beside St. Paul's Church, on Broadway, and may be considered as pointing its white finger to heaven in appeal against the severe doctrines under which these prisoners are sought to be punished. I refer to Thomas Addis Emmett.

In 1806, two men, Smith and Ogden, were put upon trial, charged with aiding Miranda and the people of Caraccas to effect a revolt against the Government of Spain, which, it was said, was at peace with the United States. They were indicted under a statute of the United States; and if it had turned out on the trial that the United States was certainly in a condition of peace with Spain, they might have been convicted. However, that was a question of fact left to the Jury. The learned Judges, pure and able men, entertained views very hostile to the notions of the accused, and were quite as decided in those views as his honor Judge Grier in the summary disposition he made of the so-called pirates in Philadelphia. The trial came on, and, with the names of the Jurors on that trial, there are preserved to us the names of Counsel, whose career is part of history. Among them were Nathan Sanford, Pierpoint Edwards, Washington Morton, Cadwallader D. Colden, Josiah Ogden Hoffman, Richard Harrison, and Mr. Emmett, already named. Well, there was an effort made to disparage any such enterprise as Miranda's, and any such aid thereto as the accused were charged with giving. The Counsel endeavored to prove that the intent was a question of law, and the fact had nothing to do with it. Colden, in his argument, said, "Gentlemen, all guilt is rooted in the mind, and if not to be found there, does not exist, and whoever will contend against the proposition must fight against human nature, and silence his own conscience."

We do not often find an opportunity, gentlemen, to regale ourselves with anything that emanated from the mind of Mr. Emmett. It is peculiar to the nature of his profession that most of what the advocate says passes away almost at the moment of its utterance. When Mr. Emmett comes to allude to the disfavor sought to be thrown on revolutionary ideas by the eminent counsel for the prosecution, he says:

"In particular, I remember, he termed Miranda a fugitive on the face of the earth, and characterized the object of the expedition as something audacious, novel, and dangerous. It has often struck me, gentlemen, as matter of curious observation, how speedily new nations, like new made nobility and emperors, acquire the cant and jargon of their station.

"Let me exemplify this observation by remarking, that here within the United States, which scarcely thirty years ago were colonies, engaged in a bloody struggle, for the purpose of shaking off their dependence on the parent State, the attempt to free a colony from the oppressive yoke of its mother country is called 'audacious, novel, and dangerous.' It is true, General Miranda's attempt is daring, and, if you will, 'audacious,' but wherefore is it novel and dangerous?

"Because he, a private individual, unaided by the public succor of any state, attempts to liberate South America. Thrasybulus! expeller of the thirty tyrants! Restorer of Athenian freedom! Wherefore are you named with honor in the records of history?

"Because, while a fugitive and an exile, you collected together a band of brave adventurers, who confided in your integrity and talents—because, without the acknowledged assistance of any state or nation, with no commission but what you derived from patriotism, liberty, and justice, you marched with your chosen friends and overthrew the tyranny of Sparta in the land that gave you birth. Nor are Argos and Thebes censured for having afforded you refuge, countenance, and protection. Nor is Ismenias, then at the head of the Theban government, accused of having departed from the duties of his station because he obeyed the impulse of benevolence and compassion towards an oppressed people, and gave that private assistance which he could not publicly avow."

Mr. Emmett, remembering the history of his own name, and the fate of that brother who perished ignominiously on the scaffold for an effort to disenthrall his native land, after that outburst of eloquence, indulged in the following exclamation:

"In whatever country the contest may be carried on, whoever may be the oppressor of the oppressed, may the Almighty Lord of Hosts strengthen the right arms of those who fight for the freedom of their native land! May he guide them in their counsels, assist them in their difficulties, comfort them in their distress, and give them victory in their battles!"

I have thought proper to fortify myself, gentlemen, by reference to this man of pure purpose, finished education, and thorough knowledge of international law, in what I said to you, that the principles which lie at the base of this American revolution, call it by what name you please, have been known and recognized at least as long as the English language has been spoken on the earth, and will be known forever—they furnishing certain rules, the benefit of which, I hope and trust, under the providence of God, after the enlightened remarks of the Court, and through your intervention, may be extended to our clients.
