“Resolved, that six companies of expert riflemen, be immediately raised in Pennsylvania, two in Maryland, and two in Virginia…that each company, as soon as completed, shall march and join the Army near Boston, to be there employed as light infantry, under the command of the chief Officer in that army,” said the Continental Congress resolution.
