On March 8, 1868, a skiff sent to Sakai was attacked by samurai of the Tosa clan; 11 sailors and Midshipman Guillou were killed (a monument in Kobe is now erected to their memory). At the time, the port of Sakai was not open to foreign ships, and the Tosa troops were in charge of policing the city. This incident was dramatised in a famous short story, Sakai Jiken, by Mori Ōgai.
