Next comes the letter itself. And here mark, if you please, first, the date, which is the 1st of March. This was at the very moment when the Rebellion was completely organized, and had assumed at all points the undisguised front of war. By various acts of violence it had forcibly dispossessed the National Government of all its military posts in the whole extensive region, except Fort Sumter and Fort Pickens, which it held in siege,--while, by other formal acts, it had assumed to dispossess the National Government of all jurisdiction, civil or military, throughout this region. That such acts constituted “levying of war,” within the meaning of the Constitution, is too plain for argument. This phrase, borrowed from the early statute of Edward the Third, has received positive interpretation in the country of its origin, according to which its meaning is clear. There is no better authority than Sir William Blackstone, who, when considering what is “levying of war,” says: “This may be done by taking arms, not only to dethrone the king, but under pretence to reform religion or the laws, or to remove evil counsellors, or other grievances, whether real or pretended: for the law does not, neither can it, permit any private man or set of men to interfere forcibly in matters of such high importance.”[129] And Lord Mansfield, Chief-Justice of England, on the trial of Lord George Gordon, declared it to be “the unanimous opinion of the Court, that an attempt, by intimidation and violence, to force the repeal of a law, was a levying war against the king, and high treason.”[130] I quote these authorities simply that this statement may not rest at any point on my assertion. At the date of this letter, then, there was actual levying of war by Jefferson Davis and his associates against the Government of the United States. And let me add, that this levying of war was not merely that moderate constructive levying of war described by Blackstone, but open, earnest, positive war, backed by armies and by batteries.
