Fort Mifflin

3d. night. A considerable number of the Enemys boats pass'd and repass'd in the course of the night, near the Shore of Province Island-it appears that this Communication between their Fleet and Philadelphia is established, and what will surprise you perhaps, is that it is a sure one, there being no Interruption on our part-we cannot cannonade them from the Fort, the shade of Trees prevents our being informed of their passage otherwise than by the noise of oars, and firing at sounds would be wasting pretious Ammunition.
