The 2nd Continental Congress passed a resolution on 10 June 1775, in creating the Continental Army from all the available colonial forces and militias around Boston; they appointed George Washington, a Congressman of Virginia, as the General and Commander-in-Chief of the Continental Army. It was vital for General Washington's army to seize Boston to help interdict the Royal Navy's flow of supplies and reinforcement of troops to the British. Under-equipped and lacking gunpowder and supplies, Washington greatly depended in supplying his force from the surrounding colonial armies and navies, and from any cache that came from captured British ships of provision and matériel values.
