Admiral Edward Boscawen (1711–1761) engaged a French fleet in the Newfoundland fog and, in capturing the sixty-four-gun Alcide (and the Lys), discovered a specific piece of intelligence. Among the French Admiral Hocquart’s papers was a document relating how French troops, working in concert with a general Acadian-Indian uprising, planned to pit some 8,000 men against 3,000 British in an attempt to attack Halifax. Thousands of scalping knives were also found packed into the ships’ holds. Also onboard the Alcide was Francois-Pierre de Rigaud de Vaudreuil, governor of Trois-Rivières (returning from France). He was taken as a prisoner to Halifax. While in prison, Vaudreuil met another prisoner, acting as a British spy, named Thomas Pichon. Unsuspecting, Vaudreuil shared a map and French plans for seizing Halifax with Pichon. The information was passed on.
