In 1758, Joseph Broussard, also known as Beausoleil by the locals, led raids against British vessels sailing in the Bay of Fundy and the Cumberland Basin. Brossard, under orders from Governor Pierre de Rigaud de Vaudreuil, fitted out a small privateer and was successful in capturing some prizes in the Bay of Fundy. Aided by his four sons and the Acadians who had taken refuge along the Petitcodiac River, he continued to harass the British forces.
This provoked the British into initiating two raids of their own. The first took place in February in Shediac. The second raid took place at the settlement of Shepody in March, where the British were shocked to find that the Acadians had already begun rebuilding their homes.
On 28 June, George Scott learned of reports that cattle were stolen outside of Fort Beausejour; the British issued an order for Captain Beloni Danks to send 75 men up the Petitcodiac River. They arrived in Moncton the following night, and about 30 Acadians began firing at their vessel. However, Danks held his offensive position, and the British killed 19 Acadians, taking nine others prisoner. He and his troops continued to sail up the river the next day; they sent 60 men to burn a settlement 9.7 km (6 mi) west of Moncton. Historians presume that the area had already been deserted.
Acadians continued to survive in the region, overcoming the results of the raids. Scott sailed back to the region to search for Beausoleil and to weaken the Acadians before the winter. He arrived in Moncton near midnight on 12 November, but the tide of the Petitcodiac River prevented him from sending more than twelve men. They came back the next morning with 16 prisoners. Scott was told that the area was virtually defenceless, so he sent three parties to La Chapelle (now Bore Park in Moncton), Silvabro (now Lewisville), and Jagersome (now Dieppe). Scott recorded no deaths or prisoners, but all buildings in sight were burned, and cattle were brought back onto the vessel.
Additional raids by Scott between 14 and 17 November captured a dozen Acadian prisoners, burned settlements, and uncovered Beausoleil's own schooner. The crew sent an Acadian prisoner on the 17th to request the surrender of the remaining residents, but when he returned, he reported that they had all begun to flee to Cocagne, Shediac, and the settlements around the Miramichi River. This prompted Scott to return to Fort Frederick in Saint John.
