By going up the North River, he secures a retreat for his army through Canada, but the ships must return if they return at all, the same way they went; as our army would be in the rear, the safety of their passage down is a doubtful matter. By such a motion he shuts himself from all supplies from Europe, but through Canada, and exposes his army and navy to the danger of perishing. The idea of his cutting off the communication between the eastern and southern states, by means of the North River, is merely visionary. He cannot do it by his shipping; because no ship can lay long at anchor in any river within reach of the shore; a single gun would drive a first rate from such a station. This was fully proved last October at Forts Washington and Lee, where one gun only, on each side of the river, obliged two frigates to cut and be towed off in an hour's time. Neither can he cut it off by his army; because the several posts they must occupy would divide them almost to nothing, and expose them to be picked up by ours like pebbles on a river's bank; but admitting that he could, where is the injury? Because, while his whole force is cantoned out, as sentries over the water, they will be very innocently employed, and the moment they march into the country the communication opens. The most probable object is Philadelphia, and the reasons are many. Howe's business is to conquer it, and in proportion as he finds himself unable to the task, he will employ his strength to distress women and weak minds, in order to accomplish through their fears what he cannot accomplish by his own force. His coming or attempting to come to Philadelphia is a circumstance that proves his weakness: for no general that felt himself able to take the field and attack his antagonist would think of bringing his army into a city in the summer time; and this mere shifting the scene from place to place, without effecting any thing, has feebleness and cowardice on the face of it, and holds him up in a contemptible light to all who can reason justly and firmly. By several informations from New York, it appears that their army in general, both officers and men, have given up the expectation of conquering America; their eye now is fixed upon the spoil. They suppose Philadelphia to be rich with stores, and as they think to get more by robbing a town than by attacking an army, their movement towards this city is probable. We are not now contending against an army of soldiers, but against a band of thieves, who had rather plunder than fight, and have no other hope of conquest than by cruelty.
