The attack at Mocodome was a battle which occurred during Father Le Loutre's War in present-day Country Harbour, Nova Scotia[a] on February 21, 1753 which saw two British mariners and six Mi'kmaq killed.

The battle ended any hope for the survival of the Treaty of 1752 signed by Governor Peregrine Hopson and Mi'kmaq chief Jean-Baptiste Cope.

By the time Cornwallis had arrived in Halifax, there was a long history of the Wabanaki Confederacy (which included the Mi'kmaq) attacking British colonists attempting to establish new settlements along the New England frontier in Maine (See the Northeast Coast Campaigns 1688, 1703, 1723, 1724, 1745, 1746, 1747).

[2][3][4] To prevent the establishment of a permanent British colonial presence in the region, Mi'kmaq raided the New England settlements of present-day Shelburne (1715) and Canso (1720).

A generation later, 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 their new settlements, British fortifications were erected in Halifax (1749), Bedford (Fort Sackville) (1749), Dartmouth (1750), Lunenburg (1753) and Lawrencetown (1754).

[citation needed] According to Charles Morris's account, John Connor and three other mariners onboard the British schooner Dunk from Canso, Nova Scotia, put into Jeddore and looted Mi'kmaq-owned stores, which consisted of 40 barrels of provisions given them by the Governor.

[13][14] In contrast, according to Anthony Casteel, after looting provisions from the Mi'kmaq at Jeddore, the Dunk accidentally was shipwrecked and two of the four crew members drowned.
