Commanders of Battle Squadrons
In cooperation with Jeff Donahoo
The format for names is Japanese style: rank; last name, first name; (if known, Japanese Naval Academy at Etajima class), note that traditionally it indicated the imperial year, which was based on the mythical founding of Japan by Emperor Jimmu in 660 BC.
Dates are given thus: day.month.year
Commanders marked with * are known to have died.
