Michel de Grammont (1645-1666) was a pirate captain based in Avalon. When Red Rodney Radcliffe learned that William Radcliff intended to attack the Avalon pirates, Grammont became the high captain of the fleet, mainly because he was the least disliked among his colleagues.
However, Grammont was also inconsequential. He was a figurehead at best, which suited Red Rodney Radcliffe's plans. During the Battle of the Hesperian Gulf, Grammont was careful not to engage his ship, the Aigle d'Argent, directly in battle.
After the first day of battle, the pirate captains met aboard the Aigle d'Argent to discuss their next course of action. Most assumed that Radcliff's Armada had turned and run. The next morning proved them wrong, and the pirates fled.
Avalon fell in short order to Radcliff's Armada, and Grammont was killed along with the rest of the pirates.
