In November 1776, the Pennsylvania Council of Safety appointed Romans "Engineer" and ordered that he be furnished with the means to conduct an experiment in "destroying distant objects by fire." Unfortunately, there is no further record of this "experiment." Romans also continued to produce maps, including two of Connecticut, one centered on Philadelphia, including most of New Jersey and Delaware, and portions of Maryland and Pennsylvania, showing the location of the "Grand American Winter Camp 1778" at Valley Forge, and a map of the "Northern Department of North America".
