For additional intelligence regarding the varying widths of the river at likely crossing places, see Delaware Fording Places, 16 June 1777, enclosed in Benedict Arnold’s letter to GW of that date. For the British attempt to cross the Delaware in the vicinity of Coryell’s Ferry on 8–9 Dec. 1776, see GW to Hancock, 11 Dec. 1776, and note 1.
