To Major General John Sullivan
Head Quarters Middle Brook
17th June 1777. 3 OClock.
I have both your favs. of this Morning.1 The Enemy last night sent off all their spare Baggage and Women to Brunswic, and the deserters say are preparing for some move, none more probable than an attempt upon this post. Considering the extent of the Ground we have to defend, we want force to make a proper resistance. You will therefore immediately upon the Rect of this detatch one thousand Continental Troops and one thousand Militia under such Officers as you think proper, with orders to proceed ’till they arrive at Steels Gap near Steels Tavern which is about two Miles from hence,2 They will there receive orders where to encamp. As an encouragement to the Militia, let them know that whatever Baggage or Spoils of any kind they can take from the Enemy shall be appropriated to their Benefit. A party a few days ago took a Waggon between Amboy and Brunswic, so valuable, that the Sale amounted to 1700 dollars. It contained Officers linen and other Cloaths.
Besides keeping out scouting parties endeavour to get some of the Militia Officers, who are acquainted upon the princetown & Cranberry Roads, to go and try to engage some of the Inhabitants to keep a good look out and watch if the Enemy advance upon either of these Roads in large Bodies with Cannon & Waggons. They need not notice small light scouting Parties. What ever intelligence they gain let them send it immediately to you. To establish Signals between your post and this will be of the utmost consequence. To try the Experiment, if you will kindle a Fire this Evening upon some part of Sourland Hill, nearest to yr Incampt we will, if we discover it, answer it by Fires from Steels Gap and Waynes Gap, you may then inform us which is most conspicuous to you. Waynes Gap will be most easterly.3 I have sent you one of my Glasses by the Bearer, it is a pretty good one. Genl Arnold writes me word that he sent four Waggon load of Cartridges to Flemingtown,4 be pleased to forward them immediately here. I am Dear Sir Yr most obt Servt
LS, in Tench Tilghman’s writing, NhHi: Sullivan Papers. After sealing the letter Tilghman wrote Sullivan a brief note on the cover: “another of yours just come to hand.”
1. Sullivan’s letters to GW have not been found.
2. Steele’s Gap is northwest of present-day Boundbrook in the First Watchung Mountains. Steele’s Tavern was located on a road that ran along the foothills from the Old York Road up to Pluckemin.
3. Wayne’s Gap is east of Steele’s Gap and due north of Boundbrook in the First Watchung Mountains. GW’s aide-de-camp Tench Tilghman wrote to Sullivan on 18 June: “Yours from Garrisons Tavern reached his Excellency about Midnight. Genl D’Borre reached Steels Gap about three this Morning. You need send on no more Troops either continental or Militia at present. Before this detatchment was called off from you, the Matter was well considered and it was determined, upon the information recd that the Enemy having neither Baggage, Tents nor Boats with them, that they could not intend at present to make their push for the River, and that the most probable cause of their coming out was to attempt a Coup de Main upon this Army, which, if Genl Howe leaves in his Rear, and attempts to cross Delaware, will certainly give him the finishing Blow. Your Fire was plainly discovered and this day a signal for mutual information will be fixed upon. I imagine what you call the grand Picquet is the Post at Somerset Court House, which is not only naturally strong, but, they have been fortifying several days. His Excellency thinks you had better employ yourself upon their Rear, by small parties, than attempt a stroke of any magnitude upon the wing next to you which is composed of their best troops” (DLC:GW).
