To Brigadier General Hugh Mercer
N. York Septr 3. 1776
From the present complexion of our Affairs It appears to me of the utmost Importance & that the most Salutary consequences may result from our having a strong Encampment at the post on the Jersey side of the North River, opposite to Mount Washington on this Island—I therefore think It adviseable & highly necessary that you detach such a Force from Amboy & Its dependencies under the Command of an Officer of Note, Authority & influence, with a Skilfull Engineer to lay out such additional Works as may be Judged Essential & proper & the situation of the Ground will admit of—they should be begun & carried on with all possible diligence and dispatch.1
It will be proper that a considerable Quantity of Provision should be collected for the maintenance & support of the Camp, & for this purpose I wish you to have proper measures adopted to procure It & have It deposited there & at places of Security not far distant.
As the Continl Officer now at this post will take rank & the command, probably of any you may send, Unless he should be a Genl Officer, I think & wish if you have One that possibly be spared & in whose Judgemt, activity & Fortitude you can rely, that he may be appointed to the command rather than an Officer of Inferior rank. I am &c.

1. Mercer received GW’s orders this night and ordered a detachment commanded by Brig. Gen. James Ewing to begin enlarging the works on the Palisades above Burdett’s Ferry across the Hudson River from Fort Washington (see Mercer to Hancock, 4 Sept., DNA:PCC, item 159). Begun in mid-July, these works were called Fort Constitution at this time but were renamed for Maj. Gen. Charles Lee on 19 October. The fort was captured by the British on 20 November.
