To Colonel William Malcom
[White Plains, 7 September 1778]1
Brigadier General Du Portail Chief Engineer is by my orders on a visit to the posts in the Highlands, to examine into the state of the fortifications carrying on there. It is my wish that Col: Koshiosko may comminicate every thing to this Gentleman, who is at the Head of the department, which he may find requisite for the purpose he is sent upon. I am persuaded you will show him every proper attention. I am Sir Yr Most Obedt ser.
