Shimamura Hayao

Marshal-Admiral Baron Shimamura Hayao (島村 速雄; September 21, 1858 – January 8, 1923) was a Japanese admiral during the First Sino-Japanese and Russo-Japanese Wars as well as one of the first prominent staff officers and naval strategists of the early Imperial Japanese Navy. He was an excellent tactician, but unlike many military men, he did not seek honor. He would defer credit to his colleagues, refrain from boasting, and openly share his failures with others. His character garnered him much respect. He remained a lifelong friend of his classmate from the Imperial Japanese Naval Academy, Katō Tomosaburō.
