The Darkest Hours

The Russo-Japanese War (1904–1905) was fought with relatively greater restraint regarding prisoner treatment than most contemporaneous conflicts — both sides initially adhered to the 1899 Hague Conventions on laws of war, and Japan's treatment of Russian prisoners surprised Western observers accustomed to expecting Asian armies to disregard such norms. The war nonetheless produced significant civilian suffering during the siege of Port Arthur and the brutality of naval engagements. Its primary atrocity legacy is the Mukden massacre and the treatment of Korean civilians under Japanese occupation — a prelude to the far more systematic brutality Japan would inflict in subsequent decades.
