With the war in full swing and a Commander-in-Chief on his way to Boston, the Continental Congress took the next step of finding a way to organize the troops.
So naturally they formed a committee. The Committee of Seven (maybe all the good names were taken?) worked diligently for about three weeks to put together a plan that would indicate just who could fight and how they would be organized. There were still some details to iron out, but in the meantime the disaggregated militias were getting the job done. All that remained was to aggregate them into a single fighting force.
