February 19 in Military History — On This Day

Battle of Mukden

The largest land battle in history to that point, Mukden involved over 600,000 men across a front stretching nearly 100 kilometers. Oyama and Kodama executed a massive double-envelopment, swinging five armies around the Russian flanks in a Manchurian winter. Despite fighting tenaciously, Russian forces were outmaneuvered as Japanese columns threatened encirclement from both sides. Kuropatkin ordered a desperate retreat northward through a narrowing corridor, managing to escape annihilation but losing the city of Mukden and suffering catastrophic casualties. The retreat lasted weeks, with the Russian army dissolving into near-chaos.

Mukden was the decisive land battle of the war and the largest land engagement the world had yet seen. It destroyed Russia's will to continue land operations, and coming two weeks after Bloody Sunday in St. Petersburg, it made the war politically untenable for the Tsar. The battle established new norms for mass industrial warfare.

Battle of Iwo Jima

US Marines landed on a volcanic island defended by 22,000 Japanese troops in an elaborate network of tunnels, bunkers, and caves. General Kuribayashi's strategy was to inflict maximum casualties rather than defend the beaches. The Marines fought yard by yard through the underground defenses. The iconic flag-raising on Mount Suribachi was captured in the war's most famous photograph. Of the 22,000 Japanese defenders, only 216 survived.

The ferocity of Japanese resistance convinced American planners that an invasion of the Japanese home islands would cost up to a million American casualties — a calculation that influenced the decision to use the atomic bomb. Admiral Nimitz said: 'Among the Americans who served on Iwo Jima, uncommon valor was a common virtue.'

Battle of Iwo Jima Begins

U.S. Marines stormed the beaches of Iwo Jima against ferocious Japanese resistance. Unlike previous island assaults, the Japanese fought from an elaborate underground tunnel system rather than defending the beaches, resulting in immediate and sustained American casualties.

Iwo Jima's 36-day battle produced nearly 26,000 American casualties and became a symbol of Marine Corps valor; Admiral Nimitz said 'uncommon valor was a common virtue.'
