On May 9, 1690 English forces under Sir William Phipps attacked the capital of Acadia of Port Royal with a fleet of seven vessels and 700 men.
[3] Upon Baptiste's return to Acadia, Governor Joseph Robineau de Villebon commissioned him to protect Acadian interests as a privateer.
In early June 1694, Baptist arrived at Cape Sable and scattered the New England fishing fleet, taking five vessels into Fort Jemseg[5] on the Saint John River.
[9] In the summer of 1696, Baptiste led Pierre Le Moyne d'Iberville's expedition out of Acadia to attack strongholds on the New England coast.
After having captured two frigates at the mouth of the Saint John River, the first target was the vitally important port at Pemaquid (present day Bristol, Maine).
On October 18 the New England troops arrived opposite the fort, landed three cannons and assembled earthworks on the south bank of the Nashwaak River.
Two New England privateer ships arrived at the scene but Baptiste was able to beat them back and safely return to Grand Pré with his prizes.
[16] Baptiste was protecting Acadian fishing interests off of Acadia when he was captured in 1702 and again imprisoned in Boston on the eve of Queen Anne's War.
[18] New France and Acadia made significant diplomatic efforts to get him back, insisting that he be released as part of a prisoner exchange involving captives taken by French and Indian raiders in the 1704 Raid on Deerfield.
Difficulties in obtaining Baptiste's release also lead to the delay in the return of another prominent prisoner, Acadian Noël Doiron.
Baptiste eventually returned to Acadia in 1706 and for the rest of Queen Anne's War served as port captain of the Acadian settlement of Beaubassin.
[19] Because of his immense knowledge of the North Atlantic coasts, the Governor of Plaisance, Philippe Pastour de Costebelle consulted Baptiste on the site for the new settlement on Cape Breton Island, Louisbourg (1714).
