Drawing on memoirs and interviews, the article explores the plotters' motivations, post-takeover plans, and ultimate failure. It highlights how Bourguiba's coup-proofing strategies shaped the plot and its outcome, concluding with a discussion on the foiled coup's lasting impact on Tunisian civil-military relations.
