A formal system of “Rules and Articles of War” was adopted, and provision was made for organizing a military force fully adequate to meet such additional troops as England might despatch to the support of General Gage. Further than this, all proposed enforcement by the British crown of the offensive Acts of Parliament, was declared to be “unconstitutional, oppressive, and cruel.” Meanwhile, the various New England armies were scattered in separate groups, or cantonments, about the City of Boston, with all the daily incidents of petty warfare which attach to opposing armies within striking distance, when battle action has not yet reached its desirable opportunity. And yet, a state of war had been so far recognized that an exchange of prisoners was effected as early as the sixth day of June. General Howe made the first move toward open hostilities by a tender of pardon to all offenders against the Crown except Samuel Adams and John Hancock; and followed up this ostentatious and absurd proclamation by a formal declaration of Martial Law. The Continental Congress as promptly responded, by adopting the militia about Boston, as “The American Continental Army.” On the fourteenth day of June, a Light Infantry organization of expert riflemen was authorized, and its companies were assigned to various Colonies for enlistment and immediate detail for service about Boston. On the fifteenth day of June, 1775, Congress authorized the appointment, and then appointed George Washington, of Virginia, as “Commander-in-Chief of the forces raised, or to be raised, in defence of American Liberties.” On presenting their commission to Washington it was accompanied by a copy of a Resolution unanimously adopted by that body, “That they would maintain and assist him, and adhere to him, with their lives and fortunes, in the cause of American Liberty.”
