They were, moreover, threatened with immediate invasion. The Proclamation of the President assigned, as their first probable duty, to the military contingents called for from other States, to repossess the Federal Government of property which it could not repossess without an actual invasion of the discontented States. The Congress of the Union was not then in session. It had adjourned, after having omitted to confer upon the Federal Executive the power to resort to measures of coercion, which had been under discussion during its sitting. The commission in question was issued as one of the measures of forcible resistance to this exercise of federal power, claimed--whether rightfully or wrongfully, is not the question here--to be unlawful by the governments of all the States against which it was directed, and to which those governments enjoined forcible resistance upon, and authorized it by, their citizens. I contend, therefore, that whether the action of the Federal Government or of the State government was justifiable or unjustifiable, no citizen of any of the States which authorized and enjoined such resistance is criminally responsible, whether he espoused one side or the other in the unhappy controversy, either to the General Government or to the government of the State of which he is a citizen, so long as he acted in good faith, and in the honest belief that the government to which he adhered was acting within the legitimate scope of its constitutional powers. We contend that every sovereign has necessarily power to defend its sovereignty, and to decide the mixed question of law and fact as to whether it has been infringed; that there can be no sovereign, or defence of sovereignty, without subjects to whom the sovereign's mandate and authority are a protection; and that as one sovereign cannot lawfully punish another, who is his equal, by personal pains and penalties, for resistance, after he is subdued, so neither can punish the subject of both who, in good faith and under honest convictions of duty, adhered to either in the struggle. Now, if your honors please, I pass to the next proposition, which is: That the defendants, who are citizens of the States calling themselves Confederate States, cannot be convicted under this indictment, if they in good faith believed, at the time of the capture of the Joseph, that the political _status_ of those States, as members of the Federal Union, had been legally terminated, and that they had thereby ceased to be citizens of the United States, and made the capture in good faith, under the commission in evidence, as a belligerent act,--such States being, as they supposed, at war with the United States.
