Sixteenth Camp, a Mile and a Half beyond Georgetown. 18-21 July 1782. Eight miles from the previous camp at Alexandria. Details concerning the ferries over the Potomac, which the had crossed before reaching Georgetown (then in Maryland) on the east bank of the river, are given in the description of the wagon train's 1781 march in the opposite direction, in Itinerary 6. The stream shown here is a small segment of Rock Creek in what is now the city of Washington, D.C. The camp was located on high ground on the east bank of the creek, presumably in the vicinity of the present P Street Bridge, along the road from Georgetown to Bladensburg. In 1782 the District of Columbia was still in the future and L'Enfant's geometric grid had not yet been superimposed on the old road pattern. Cf. Colles, Survey, Plate 65.

The army had covered the route from Williamsburg to Georgetown--167 miles according to the mileage figures on the maps--in 18 days (2 of them halts) and 16 marches. The wagon train, when proceeding southward by forced marches over roughly the same route in September-October 1781, had covered it in 12 daily marches (no halts). Although the mileage estimates for the two marches do not exactly coincide, it would appear that the average daily march for the army in July 1782 was a bit over 10 miles, whereas that for the wagon train in 1781 had been over 16 miles a day.
