Battle context
The Battle of Mukden was the last and most decisive major land battle of the Russo-Japanese War, fought near Mukden in Manchuria from 20 February to 10 March 1905. With Japan fielding roughly 270,000 troops against a Russian force of approximately 292,000, it ranked among the largest land engagements fought before World War I. Combined casualties exceeded 165,000. The battle effectively ended large-scale land operations in the war, leaving Russia without the capacity to mount a decisive counteroffensive in Manchuria and accelerating the conditions that led to the war's conclusion.
