Fort Frederick was a British redoubt that was built to help fortify their acquisition of Placentia in Newfoundland Colony. Under the command of Samuel Gledhill, it served as the military headquarters for Newfoundland from 1721 to 1746. There was a report that the Mi'kmaq were involved in a raid of Placentia during Father Rale's War, in which they were said to have killed 200 English. Governor Drummer did not believe the report.
