Kennedy was commander of
Lady Franklin's sponsored expedition in 1851 to find her husband,
Sir John Franklin, using the
ketch Prince Albert. His second in command was
Joseph René Bellot, a French Navy sub-lieutenant. The expedition was well organized as Kennedy was well versed in northern travel, and used as many experienced men as he could find and outfitted them in native clothing. While the expedition did not find Franklin, it did acquire substantial knowledge of the Canadian Arctic. This was because of his preparedness and leadership: adapting the dress and survival techniques of the
Inuit peoples, bringing a custom-made
kayak for independent travel away from the ship, stopping in Greenland to purchase a dog-sled team, and asking the locals for the best routes and information of the area. They returned to Britain in October 1852 without losing any men, having recorded the flora, fauna, and cartography of the area; a first for any Arctic exploration to that date. Lady Franklin placed Kennedy in charge of her auxiliary steamship
Isabel to search the Arctic via the
Bering Strait early in 1853. However, most of the crew including his sailing master Robert Grate mutinied at
Valparaiso in August, claiming the vessel was too small for her mission. After two years trading around the South American coast while trying to find another crew willing to sail to the Arctic, he gave up and returned the
Isabel to England in 1855. After returning to England Captain Kennedy wrote a book about his expedition, earning further acclaim and public recognition. The British Historical Society invited him to present his drawings and findings to its members. Upon his return to Canada in 1856, he became active in establishing a mail service between
Toronto and the
Red River Colony. == Legal challenge to Hudson's Bay Company ==
