Battle of Tsushima

The most decisive naval battle since Trafalgar, Tsushima was the culmination of Russia's extraordinary 18,000-mile voyage of the Baltic Fleet around the world to relieve the Pacific Squadron — only to find Port Arthur already fallen. Admiral Tōgō intercepted Rozhestvensky's exhausted fleet in the Korea Strait and executed the famous 'crossing of the T,' bringing his full broadside to bear on the Russian line. In two days of fighting, Japan sank or captured virtually the entire Russian fleet. Of 38 Russian warships, 21 were sunk, 7 captured, and 6 interned. Only 3 escaped to Vladivostok. Russian casualties dwarfed Japanese losses by a ratio of nearly 180 to 1.

Tsushima was one of the most lopsided naval victories in history. It ended any Russian hope of continuing the war and compelled Tsar Nicholas II to accept President Roosevelt's offer of mediation. The battle proved the decisive role of gunnery training, modern fire control, and fleet coordination — lessons that would shape naval doctrine for decades.

⚔️📍 North Atlantic Ocean1941

Bismarck Sunk by Royal Navy

After being crippled by a torpedo that jammed her rudder, the German battleship Bismarck was surrounded by Royal Navy ships and bombarded until sinking. German survivors later claimed the crew scuttled the ship; the British claimed their gunfire sank her.

The Bismarck's sinking ended the threat of German surface raiders against Allied Atlantic convoys and demonstrated that no warship could operate in modern seas without air cover.

Outcome

Bismarck sunk; 2,100 of 2,200 crew killed

Casualties

2,100
