In this letter to Major Gilbert M. Elliott, Lieutenant Hathaway includes what he describes as a "sketch of River from Ellis Ford to Extent Picketed by left [indecipherable] of 102 Regt."

The sketch presented at the top of the page depicts a river with scattered houses on either side. Labels and descriptions are plentifully inscribed along the map, indicating types, depths, and other characteristics of geographic features, along with names of the owners of some houses. Mr. Ellis's house along with the eponymous mill and ford are labelled.
