Rare French edition of Sayer & Bennett's rare chart of Boston Harbor revised and issued in Le Rouge's Pilote Americain Septentrionale, which was compiled specifically for use by the French Navy during the American Revolution.
A note following the title indicates that the chart was based on British surveys. The map is drawn from Sayer & Bennett's map of 1776, depicting Boston Harbor from roughly Deer Island to Hull. The map includes extensive soundings, the Harbor's many hazards are marked, and specific courses and sailing directions are provided for navigating the difficult waters. For example, accessing the "best channel" for the final approach to Boston requires one to sight on the "Charlestown Tree" situated on or near Breed's Hill. On land, there is a full street plan of Boston with several landmarks indicated, while the towns of Dorchester, Milton, and Hull are shown schematically. To the northwest are the "Ruins of Charlestown," indicating that the chart was completed sometime after the June 1775 Battle of Bunker Hill.
The Le Rouge edition is better-engraved than the Sayer & Bennett edition and rarer on the market.
