The Battle of Tannenberg was a significant World War I conflict fought between the Russian Empire and the German Empire in August 1914. It took place near the town of Tannenberg (now Stębark, Poland) in East Prussia.

Here's an overview of the battle:

The Battle of Tannenberg was a pivotal clash between Russian and German forces during the early stages of World War I. In August 1914, the Russian Second Army, under General Alexander Samsonov, advanced into East Prussia, aiming to strike at German positions. However, German General Paul von Hindenburg and his chief of staff, Erich Ludendorff, devised a masterful plan to encircle and trap the Russian army.

Employing superior German intelligence and coordination, Hindenburg and Ludendorff executed a daring double envelopment. They swiftly launched a surprise attack on the Russian Second Army's flanks, while German reserves blocked their retreat routes. The Russian forces were caught off guard and suffered from disorganization and poor communication.

The battle resulted in a resounding victory for the German Empire. The Russian Second Army was decimated, with thousands of soldiers captured, killed, or wounded. The defeat had far-reaching consequences, impacting Russia's war effort and demonstrating the effectiveness of the German military's strategic planning and execution. The Battle of Tannenberg became a symbol of German military prowess during World War I.
