The monumental four-volume Atlantic Neptune remains the defining collection of charts and maps documenting the coastline of North America during the eighteenth century. Compiled and edited under the direction of the British Admiralty, this extensive project serves as the primary legacy of Joseph Frederick Wallet Des Barres, an officer whose career spanned military engineering, colonial governance, and rigorous coastal surveying.
Military Career and Early Surveys
Trained at the Royal Military Academy, Woolwich, after studying mathematics in Basel, Des Barres received his commission into the Royal Americans in 1756. During the Seven Years' War, he contributed significantly to naval operations, capturing French entrenchments at Kennington Cove in 1758. His technical skills in surveying were later utilized to prepare naval defenses in Halifax and to chart the approaches to Quebec. In 1762, he served in Newfoundland, where he worked alongside James Cook to restore harbor defenses.

Between 1764 and 1773, Des Barres operated from his 8,000-acre estate, Castle Frederick, in Nova Scotia. He utilized the HMS Diligent to conduct an exhaustive, decade-long survey of the Atlantic coastline from Newfoundland to New York. The resulting Atlantic Neptune, published in 1777, required an estimated investment of £100,000 from the British Admiralty to document the numerous bays, shoals, and islands that previously hindered maritime navigation.
Colonial Governance
Des Barres transitioned into political administration, serving as the first lieutenant governor of Cape Breton Colony from 1784 to 1787. He developed the original urban plan for Sydney to accommodate arriving United Empire Loyalists. He later held the position of Lieutenant Governor of Prince Edward Island from 1804 to 1812. His land interests were vast, encompassing thousands of acres in New Brunswick and Nova Scotia, managed largely by his housekeeper Mary Cannon.
