Not much that I can find about this guy - only that when Okita fell sick, Nagakura sometimes commanded both the 1st and 2nd patrol. He deserted his han to come to Kyoto. After the Ishin government was set up, he was granted pardon to return to his han, and changed his name to Sugimura Yoshie. In the 15th yearof Meiji (1882), he went over to Hokkaido and became a kendo instructor in a prison there, the same prison Anji went to... (wonder if they'll meet each other there?) Nagakura resigned after several years, and built some graves for his former friends in the Shinsengumi. He later wrote a book on his Shinsengumi days, which seemed to be the main factor of his fame. Nagakura passed away in January 1915, 4th year of Taishoat the age of 76.
