Battle of Gumbinnen

The Battle of Gumbinnen, initiated by forces of the German Empire on 20 August 1914, was a German offensive on the Eastern Front during the First World War. Because of the hastiness of the German attack, the Russian Army emerged victorious.

At the outbreak of the war, Maximilian von Prittwitz's orders were very strict and clear: his German Eighth Army was to remain in its positions in East Prussia, without attempting any offensive action, as all German efforts were to be concentrated on the Western Front against France, according to the Schlieffen Plan. In addition, should the Russians increase their pressure, he was authorized to fall back as far as the Vistula River, abandoning eastern Prussia.
