. "The Tracey Mission was a Naval mission of the Royal Navy sent to Japan in 1867-1868. The mission had been requested by the Shogunate in order to help develop its Navy, and more specifically to organize and superintend the Naval school at Tsukiji, Tokyo. The mission was composed of several officers and warrant officers, but was barely able to work due to the start of the Boshin War. They soon returned to England, due to the promise of all foreign powers to remain neutral in the conflict."@en . . .
