In general character the letter is correspondence with a public enemy, in open war with our own country; or rather let me say it is correspondence with a public rebel. It is obvious that all correspondence of such a character, even without considering its special import, is open to suspicion. Throughout history it has been watched with jealous judgment, as in the cases of Bolingbroke and Atterbury in England, of Pichegru and Fouché in France. Tried even by those technical rules which in the present inquiry we reject, it may help to complete the evidence of treason itself. The well-chosen language of the Constitution, borrowed from an early resolution of the Continental Congress, by whom it was borrowed from the early English statute, authorizes this conclusion. According to the Constitution, “Treason against the United States shall consist only in levying war against them, or in adhering to their enemies, giving them aid and comfort.” Here are two classes of cases: the first is levying war, which Jefferson Davis, as we have already seen, was notoriously doing at the date of this letter; and the second is adhering to enemies, giving them aid and comfort. Even if mere correspondence with an enemy would not bring the author within the scope of these words, clearly and beyond all question such correspondence is calculated to give at least moral aid and comfort to the enemy. Nor is it to be disregarded on this occasion, even if it does not reach the technical requirement of treason. If we listen to the Supreme Court of the United States in the case of Bollman, we find this tribunal declaring, that, “if war be actually levied, that is, if a body of men be actually assembled for the purpose of effecting by force a treasonable purpose, _all those who perform any part, however minute, or however remote from the scene of action_, and who are actually leagued in the general conspiracy, are to be considered as traitors.”[131] Assuming the previous league, it cannot be doubted that an act of sympathy and friendship, though minute or remote, extended to persons in rebellion, would be evidence to bring the offender within the cautious grasp of the Constitution, even on technical grounds. If in the present case there was no previous league, there was at least a previous and most notorious fellowship, kindred to a league, by which the author was morally linked to the conspirators.
