Father Le Loutre's War began when Edward Cornwallis arrived to establish Halifax with 13 transports on June 21, 1749.

To guard against Mi'kmaq, Acadian and French attacks on the new Protestant settlements, British fortifications were erected in Halifax (1749), Dartmouth (1750), Bedford (Fort Sackville) (1751), Lunenburg (1753) and Lawrencetown (1754).

[6] With the establishment of Halifax, the French Canadians recognized at once the threat it represented and that the St. John River corridor might be used to attack Quebec City itself.

[10] In the fall of 1748, after King George's War, the Acadians and Mi'kmaq prevented John Gorham from landing to acquire an oath of allegiance.

[11] In 1749, at the beginning of Father Le Loutre's War, Boishebert rebuked British naval officer John Rous at St.

It was built in 1751 by the order of the Marquis de la Jonquière as a way station between Fort Beauséjour and Louisbourg and Québec.

In April 1755, while searching for a wrecked vessel at Port La Tour, Cobb discovered the French schooner Marguerite (Margarett), taking war supplies to the Saint John River for Boishébert at Fort Menagoueche.

Boishebert knew that he faced a superior force so he burned the fort and retreated up the river to undertake guerrilla warfare.
