Question

When was the battle of tannenberg broke out?​

Answer 1

Battle of Tannenberg begins. On August 26, 1914, the German 8th Army, under the leadership of Paul von Hindenburg and Erich Ludendorff, strikes with lethal force against the advancing Russian 2nd Army, led by General Aleksandr Samsonov, in East Prussia during the opening weeks of the First World War.

Answer 2

Explanation:

The Battle of Tannenberg was fought between Russia and Germany between 26 and 30 August 1914, the first month of World War I. The battle resulted in the almost complete destruction of the Russian Second Army and the suicide of its commanding general, Alexander Samsonov. A series of follow-up battles (First Masurian Lakes) destroyed most of the First Army as well and kept the Russians off balance until the spring of 1915. The battle is particularly notable for fast rail movements by the Germans, enabling them to concentrate against each of the two Russian armies in turn, and also for the failure of the Russians to encode their radio messages. It brought considerable prestige to Field Marshal Paul von Hindenburg and his rising staff-officer Erich Ludendorff.

Although the battle actually took place near Allenstein (Olsztyn), Hindenburg named it after Tannenberg, 30 km (19 mi) to the west, in order to avenge the defeat of the Teutonic Knights 500 years earlier at the Battle of Grunwald by Poland-Lithuania (which was also known as the Battle of Tannenberg in German).

I hope it helps.
