遼東半島
In 1904, Nogi was recalled to active service on the occasion of the Russo-Japanese War, and was promoted to army general in command of the Japanese Third Army, with an initial strength of approximately 90,000 men and assigned to the capture of the Russian-held Port Arthur on the southern tip of Liaodong Peninsula, Manchuria. Nogi's forces landed shortly after the Battle of Nanshan, in which his eldest son, serving with the Japanese Second Army, was killed. Advancing slowly down the Liaodong Peninsula, Nogi encountered unexpectedly strong resistance, and far more fortifications than he had experienced ten years earlier against the Chinese.
