1. Tench Tilghman wrote Jackson on this date: “Having recd intelligence that the Enemy have evacuated Philadelphia. His Excellency desires you to move immediately down towards the City with your detatchment. Upon your approach send some Officers forward to reconnoitre and see that all is clear. His Excellency would not have your detatchment enter the City tonight, but halt at a place called the Vine yard (where the Enemy had their most advanced Works) about two Miles from town. An Officer or two with small parties should be kept along the Water side to observe the Motions of the Enemy at Coopers point on the Jersey shore. Genl Arnold will go down tomorrow, and you are to take your future orders from him” (PHi: Gratz Collection).
