Philadelphia 28 Novr 1780.
I [ ] to write a Letter [ ] if I [ ] you to excuse. If I am rightly inform’d of the Situation of the Enemy the Next Embarkation will not leave above 6.000 Men in New York. Supposing this to be the Case I will go on to suppose that the french Troops with 2.000 Militia are thrown upon Long Island and march Westward. That you move down with 10.000 Men to the Neighbourhood of Kings bridge and at a proper Moment throw a Bridge over Ha[erlem] River at Haerlem and cross to the Island with 8.000 Men leaving 2.000 above Kings Bridge. That 1500 Militia are assembled at Elizabeth Town Point and  at [ illegible.] In this Situation it appears almost certain that the Enemy would abandon Fort Washington and the adjacent Heights. If so We might take Possession of them, [shore up] Intrenchments, by Lumbrs from Albany build Huts, and thus keep Possession of [that] Ground. In this Case The Enemy would probably quit New York and then we might make such powerful Diversions next Year agt Canada and Nova Scotia as [ea]sily to recover the Southern States almost by their own internal Strength but especially if Spain should send three thousand Men to operate in that Quarter. If [ ] Enemy should persist in keeping fort Washington &ca they would loose Staten [Isla]nd & their Fort at Brooklyn. If they abandon Staten Island, strengthen themselves at Brooklyn then they would necessarily loose New York. [W]hat would be the Effects of a brilliant Stroke at the close of the Campaign I need not [ ]. believe me yours
