Yamazawa Seigo made a name for himself as a war correspondent during the Russo-Turkish War, embedding with Russian forces in the Balkans between 1877 and 1878. He didn't just observe from the sidelines—at his own insistence, he joined the fighting directly and ended up commanding a Russian platoon. He saw significant action at the Siege of Pleven in Bulgaria, where his contributions earned him multiple military decorations from the Russians.
