In Council Philad. Septr 6th 1777
Sir
There is great reason to beleive that the Enemys Ships will make an attempt to weigh the Chevaux De Frize, and to destroy our Fortifications on the Delaware, with design to reach this City; whilst their Army is endeavoring to Penetrate the Country. it therefore becomes absolutely necessary for Council to pay Strict attention to these matters. The Works at Billingsport, Fort Island, Derby Creek and Bush Island, by order of His Excelly General Washington, are left almost without Guards. You will therefore immediately repair to these Works, and Post the two Companys of Militia Artillery, that are under your Command, in such way as to you may appear most advantagious — I desire you will use your utmost endeavors to have those Fortifications put into as good a state of defence as possible, under the direction of such Officer, or Officers, as His Excelly Gen: Washington has, or may order there for that purpose.
Proper attention should be paid to the Military & other stores &c, that are already, or may hereafter, be orderd there — have them carefully examined, and see that no waste or embezzelment happens.
In conjunction with the Commanding Officer of our Fleet, I request that you will exert yourself to take Burn, sink, or otherwise destroy, the Enemy's Ships or Vessels that may attempt to Invade this or the Neighbouring states. I expect in a few Days three or four Companys of the Militia from Bucks County, the whole of which or apart, as there may be occasion, I will order to reinforce you. I am Sir [&c.]
