The Attack on Port Arthur
The disintegration of the Chinese Empire under Qing Dynasty and the construction of the Trans-Siberian railroad allowed Imperial Russia to coerce the use the warm water Port Arthur on the Manchurian Liaodong Peninsula. The newly expansionist Imperial Japan, fresh from a massive and rapid technological, military, and industrial revolution during the Meiji Restoration, negotiated with Imperial Russia for a free hand in Korea while the Russians occupied Manchuria. The Russians had no respect for the upstart Japanese and even welcomed war with them as a way of reconsolidating Tsar Nicolas II rule. However, Russia was confident the Japanese would not declare war or attack because Russia was vastly superior to the Japanese in every conceivable strategic and tactical category, even 4000 miles away on the Pacific coast.
On the night of 8 February 1904, the Japanese launched a surprise attack on the Russian Pacific Fleet’s base at Port Arthur initiating the Russo Japanese War. Japanese destroyers struck the brightly lit and minimally manned Russian cruisers and battleships in outer harbor with a new weapon, the motorized torpedo. The new torpedoes were unreliable and inaccurate, and only three hit their targets and detonated. Fortunately for the Japanese, they severely damaged the Russian’s two largest battleships and Japanese battleships finished what the small Japanese destroyers started. The remaining Russian ships retreated to Port Arthur’s inner harbor under the protective guns of its landside fortifications. The Battle of Port Arthur relinquished Russian naval superiority in the Pacific to the Japanese. The Japanese invaded Korea the next day, and finally declared war on Russia two days later on 10 February 1904.
The Japanese, with air dropped torpedoes, would repeat the maneuver much more effectively 37 years later at Pearl Harbor.
