The term ‘enemies,’ as used in the second clause, according to its settled meaning, at the time the constitution was adopted, applies only to the subjects of a foreign power in a state of open hostility with us. It does not embrace rebels in insurrection against their own government. An enemy is always the subject of a foreign power who owes no allegiance to our government or country. We may, therefore, omit all consideration of this second clause in the constitutional definition of treason. To convict the defendants they must be brought within the first clause of the definition. They must be shown to have committed acts which amount to a levying of war against the United States. To constitute a levying of war there must be an assemblage of persons in force, to overthrow the government, or to coerce its conduct. The words embrace not only those acts by which war is brought into existence, but also those acts by which war is prosecuted. They levy war who create or carry on war. The offense is complete, whether the force be directed to the entire overthrow of the government throughout the country, or only in certain portions of the country, or to defeat the execution and compel the repeal of one of its public laws.
