Des Barres

Colonel Joseph Frederick Wallet Des Barres (22 November 1721 – 27 October 1824 (or 24 October 1824)) was a cartographer who served in the Seven Years' War, in part, as the aide-de-camp to General James Wolfe.[1] He also created the monumental four volume Atlantic Neptune, which was the most important collection of maps, charts and views of North America published in the eighteenth century.[2] Finally, he was the Governor of Cape Breton Island and Prince Edward Island. Colonel Des Barres is buried with his wife in the crypt of St. George's (Round) Church, Halifax, Nova Scotia.

Early life[edit]

Des Barres, who is seen as having lived through important changes in Nova Scotia's history, is thought to have been born in Basel, Switzerland, and was a member of a Huguenot family. His parents were Joseph-Leonard Vallet Des Barres and Anne-Catherine Cuvier and he was the eldest of their three children. Des Barres read mathematics and art at the University of Basel, studying under John and Daniel Bernoulli. Upon the completion of his studies he left for England.[3]:112 There he enrolled at the Royal Military Academy, Woolwich. It was there that Des Barres trained to become a military officer, and studied military surveying. His training would also benefit him later in life for surveying, map making, and coastal charting. In 1756 he was commissioned into the Royal Americans (the 62nd Foot later known as the 60th Foot).[4][3]:112

Seven Years' War[edit]

In 1756 Des Barres sailed to North America and was with Edward Boscawen's fleet when it attacked the Fortress of Louisbourg in 1758. He distinguished himself by capturing a French entrenchment at Kennington Cove.[3]:54 Soon he was put to work charting the Gulf of St. Lawrence and the approaches to Quebec, information that would be used the following year in Wolfs's assault on the City of Quebec. In 1760 he was at Halifax to prepare plans for the city's defences and naval yard.

Jonathan Binney and DesBarras met the Mi'kmaw chiefs at Arichat, Nova Scotia, in 1761, and concluded a lasting peace.[5]

By 1762 he was sent to Newfoundland to survey Harbour Grace and Carbonear and to draw up plans for new harbour defences to replace those destroyed by the French. James Cook was sent as his assistant. (Des Barres may have met Cook earlier at either Louisbourg or Halifax.)[3]:111

Atlantic Neptune[edit]

Main article: Atlantic Neptune

Des Barres made many maps of the Atlantic, mapping the coast of North American from Newfoundland to New York. His survey of the coast of Nova Scotia took approximately ten years due its length and intricacy. Des Barres was exasperated with the work stating "There is scarcely any known shore so much intersected with Bays, Harbours, and Creeks as this is" "and the Offing of it is so full of Islands, Rocks, and Shoals as are almost innumerable."[3]:115 The survey work was carried out in the summer and in the winter he would retire to his estate, Castle Frederick, in Falmouth, Nova Scotia to complete his charts and drawings. His most notable work is the Atlantic Neptune. In 1774 under direction for the British Admiralty, Des Barres compiled and edited his and many others' charts and maps of eastern North America. The completed work was published in 1777, having cost the Admiralty an estimated £100,000.[3]:187


To accommodate the arrival of the United Empire Loyalists, Cape Breton was created as a separate colony from Nova Scotia (as was New Brunswick) and Desbarres served as the lieutenant governor of Cape Breton Island from 1784 to 1787. He laid out the original plan of the capital, Sydney.[6] He was later governor of Prince Edward Island from 1804 to 1812. Dalhousie University has a number of items of Colonel Des Barres in one of its archive collections.

He died at the age of 102, and his date of death is variously given as 24 and 27 October. Colonel Des Barres is buried St. George's (Round) Church, Halifax, Nova Scotia. While he was buried beside his wife Martha, he was survived by his mistress Mary Cannon and their four children.[7] His funeral took place in St. George's Round Church in 1824.
