Philippe Pastour de Costebelle

Philippe Pastour de Costebelle (c. 1661 – October 1717) was a French naval officer and Governor of Newfoundland and then Louisbourg.

That year he was ordered to improve the fortifications and establish contact with the English colonists in St. Mary's Bay.

In 1696 Costebelle was sent to France, and thus did not participate in Pierre LeMoyne d'Iberville's celebrated and destructive Avalon Peninsula Campaign.

By the Treaty of Utrecht of 1713 Newfoundland was handed over to Britain and the king of France ordered Costebelle to evacuate the colony in the spring of 1714.

Costebelle oversaw the evacuation of French subjects from Newfoundland to Cape Breton Island, where the colony of Île-Royale was established.
