American Military History, Volume 1 by Richard W. Stewart

The First Continental Congress meeting at Philadelphia on September 5, 1774, addressed respectful petitions to Parliament and King but also adopted nonimportation and nonexportation agreements in an effort to coerce the British government into repealing the offending measures. To enforce these agreements, committees were formed in almost every county, town, and city throughout the colonies. In each colony, these committees soon became the effective local authorities, the base of a pyramid of revolutionary organizations with revolutionary assemblies, congresses, or conventions, and with committees of safety at the top.

This loosely knit combination of de facto governments superseded the constituted authorities and established firm control over the whole country before the British were in any position to oppose them. The de facto governments took over control of the militia and other colonial military resources such as armories and powder stores. They also identified which local militia officers could be trusted and which were known to be loyal to Britain. Where possible the various colonies reorganized the standing militia and formed rapid response units, including the famous Minutemen intended to turn out fully armed "in a minute's notice." In colonies where a British governor's official control over the militia could not be challenged, volunteer companies began training under the guidance of veterans of the French and Indian War. As winter turned into spring in 1775, patriot leaders were busily shaping the military forces that, if the necessity arose, might oppose the British Army in the field.
