Johanna Expedition

The Johanna Expedition, or Anjouan Expedition, was a naval operation that occurred in August 1851 during the American anti-slavery patrols off Africa. The event was unrelated to slavery and began after the seizure of the merchant ship Maria and her captain at Johanna Island. The United States Navy sent a sloop-of-war to free the captain, who was still being held, and to demand compensation for the incident. When Sultan Selim refused, the Americans briefly bombarded the island's fortifications.
