The Battle of Mukden (奉天会戦, Hōten kaisen), one of the largest land battles to be fought before World War I and the last and the most decisive major land battle of the Russo-Japanese War, was fought from 20 February to 10 March 1905 between Japan and Russia near Mukden in Manchuria. The city is now called Shenyang, the capital of Liaoning province in China. Involving 610,000 combat participants and 164,000 combatant casualties, it was the largest modern-era battle fought prior to World War I, and possibly the largest battle in world history at that point. The scale of the battle, particularly in the amount of ordnance being expended, was unprecedented in world history. The Japanese side alone fired 20.11 million rifle and machine gun rounds and 279,394 artillery shells in just over ten days of fighting (yet the Russians still fired more), matching the ammunition consumption of the German army in the entire 191-day Franco-Prussian War and more than the British had fired during the entire Second Boer War.
