Adrien de la Rivière

Adrien de la Rivière, a French cavalry knight, was captured in Malta after his horse was shot from under him in a disastrous early skirmish with the Ottomans. He fed Mustafa Pasha false information about the Maltese defences, which resulted in a failed attack by the Ottomans. His deception cost him his life – he was horribly tortured to death in front of the other slaves and captives to teach them a lesson. https://www.kickstarter.com/projects/tristanhall/1565-st-elmos-pay-the-card-game-of-war-and-history
