Charles Deschamps de Boishébert was a member of the Compagnies Franches de la Marine and was a significant leader of the Acadian militia's resistance to the Expulsion of the Acadians. He settled and tried to protect Acadians refugees along the rivers of New Brunswick. At Beaubears National Park on Beaubears Island, New Brunswick he settled refugee Acadians during the Expulsion of the Acadians.

The military history of the Acadians consisted primarily of militias made up of Acadian settlers who participated in wars against the English in coordination with the Wabanaki Confederacy and French royal forces. A number of Acadians provided military intelligence, sanctuary, and logistical support to the various resistance movements against British rule in Acadia, while other Acadians remained neutral in the contest between the Franco–Wabanaki Confederacy forces and the British. The Acadian militias managed to maintain an effective resistance movement for more than 75 years and through six wars before their eventual demise. According to Acadian historian Maurice Basque, the story of Evangeline continues to influence historic accounts of the expulsion, emphasising Acadians who remained neutral and de-emphasising those who joined resistance movements. While Acadian militias were briefly active during the American Revolutionary War, the militias were dormant throughout the nineteenth century. After confederation, Acadians eventually joined the Canadian War efforts in World War I and World War II. The most well-known colonial leaders of these militias were Joseph Broussard and Joseph-Nicolas Gautier.
