All fortifications were clearly marked, all landmarks neatly labeled, including “Mount Whoredom”

“Needing more than his rough sketch of the terrain, Washington had assigned a talented nineteen-year-old lieutenant, John Trumbull, the son of the governor of Connecticut, to do a series of maps and drawings. For one sketch of the British defenses at the Neck, young Trumbull had crawled through high grass almost to the enemy line.

For their part, the British had assigned an experienced cartographer, Lieutenant Richard Williams, who, with the help of a small crew, moved his surveyor’s transit and brass chains from one vantage point to the next, taking and recording careful sightings. The result was a beautifully delineated, hand-colored map showing “the True Situation of His Majesty’s Army and also those of the Rebels.” All fortifications were clearly marked, all landmarks neatly labeled, including “Mount Whoredom,” Boston’s red-light district. Lieutenant Williams had been appalled to find prostitution so in evidence in what was supposedly the center of Puritanism—“There’s perhaps no town of its size could turn out more whores than this could,” he noted in his journal—and accuracy demanded that this, too, be shown on the map.
