Romans soon returned to Connecticut. It is not known if Romans was present at the Battle of Bunker Hill, but he published an illustration of it, "An Exact View of the Late Battle at Charlestown, June 17, 1775." Romans also published a map of the area around Boston, "The Seat of Civil War in America", and dedicated it to John Hancock. Romans' earlier work was also used by the British in their maps, particularly in "A General Map of the Southern British Colonies", which was included in the "American Military Pocket Atlas", intended for the use of mounted British officers.
