"She hailed us and informed us she had captured a piratical vessel. The vessel was half a mile astern. Captain Parrot, of the Perry, came and made to me a report of what had taken place. I ordered him to send the prisoners on board, and I sent a few men on board the Savannah to take charge of her during the night. The vessels were then anchored. Next morning I made arrangements to put a prize crew on board the Savannah and send her to New York, and I directed the Captain of the Joseph to take passage in her. I took the prisoners from the Perry, and directed the Perry to proceed," &c. Again he testifies: "_Q._ What was your object in transferring the prisoners from the Perry to the Minnesota? "_A._ Sending them to a Northern port. The port of New York was the port I had in my mind to send them to, in the first ship from the station." The prisoners, thus taken from a piratical vessel, he determined to carry to Norfolk, and to send them thence to the North for trial. Now, if your honors please, my learned friend (Mr. Evarts) seems to say that there is no authority in law for a United States vessel to arrest pirates at sea; but if you will read the President's proclamation of 19th June you will find that he speaks of dealing with the persons who may be taken on board private armed ships as pirates. I will then ask to direct your attention to the Act of 1819 (3d Vol. Statutes, p. 510), where the President is authorized to employ public armed vessels to arrest offenders against that law. Therefore the capture of the prize was not only a part of the general law of nations, but it was particularly a thing which the commanders of ships of the United States were charged by the proclamation of the President, and by Act of Congress, to do. I now approach the other question, as to where these prisoners were apprehended, or into what District they were first brought. That they were apprehended by a warrant from the United States Commissioner in New York, is not in dispute. The question, however, is, where they were first brought. If an officer having them in charge could anchor his vessel at Baltimore, and then at Philadelphia, and then bring his prisoners to New York, it would be putting the law entirely in his hands and dissipating all its force. In ordinary cases of crime the jurisdiction is local; and that for many reasons. One is, that a man is to be tried by his peers--meaning those of his own neighborhood,--and that it is easier to procure evidence at the place where the crime is committed. The law does not give to any man the power of assigning the place of trial. In the case of offences committed on the high seas, the law declares that the accused shall be tried in the District into which he is first brought.
