Hello!
Legend of the Galactic Heroes is a series of science fiction novels written by Yoshiki Tanaka.
Ref: The story is staged in the distant future within our own Milky Way Galaxy, starting in SE 796/IC 487/AD 3596. A portion of the galaxy is filled with terraformed worlds, inhabited by interstellar traveling human beings. For 150 years, two mighty space powers have intermittently warred with each other: the Galactic Empire and the Free Planets Alliance.
Within the Galactic Empire, based on mid-19th-century Prussia, an ambitious military genius, Reinhard von Müsel, later conferred the name Reinhard von Lohengramm, is rising to power. He is driven by the desire to free his sister Annerose, who was taken by the Kaiser as a concubine. Later, he wants not only to end the corrupt Goldenbaum dynasty, but also to defeat the Free Planets Alliance and unify the whole galaxy under his rule.
In the Free Planets Alliance Star Fleet is another genius: Yang Wen-li. He originally aspired to become a historian through a military academy and joined the tactical division only out of need for tuition money. He was rapidly promoted to commodore because he demonstrated excellence in military strategy in a number of decisive battles and conflicts. He becomes the arch-rival of Reinhard, though they highly respect one another. Unlike Reinhard, he is better known for his underdog victories and accomplishments in overcoming seemingly impossible odds and mitigating collateral damages and casualties due to military operations.
