Annual Dinner 2026: The “Pirates” of Orange County- June 11, 2026

Jolly Roger
Bouchard Portrait

Join author and historian Eric Plunkett
Thursday, June 11, 2026
at Alta Vista Country Club, Placentia, CA
Social Hour / Silent Auction / Cash Bar: 5:30 p.m.
Dinner: 6:30 p.m. Presentation: 7:30 p.m.

Avast, ye lubberly swabs! Come hear local pirate lore and the true story of buccaneers’ raid on San Juan Capistrano. Historian Eric Plunkett will share swashbuckling tales he’s uncovered for his new book, The Saga of Orange County’s “Pirates”: Hippolyte Bouchard’s Attack on Mission San Juan Capistrano in 1818.
This raid even played a part in the Argentine War of Independence. And while not exactly like the pirates we know from Disneyland, tales of the exploits of Bouchard and his crew provide a compelling and enlightening window into Alta California during the collapse of the Spanish Empire.
Plunkett is a teacher and a Placentia native, and has a history degree from CSU Fullerton. He’s the author of scholarly articles, of his own Visions of California blog, and of several books (which will be available for sale).
