This sealed the deal for the German Army, as the battle was theirs to lose at this point. The Germans set a trap for the Russian army, and was also helped by the wireless intercepts of two major intelligence transmissions between Rennenkampf and Samsonov. The order was put in place but had not yet been executed, so when new commander Paul von Hindenburg organized a new attack, they did so with confidence due to the plan put in place by Colonel Maximilian Hoffman, Prittwitz’s deputy Chief of Operations. His retreat immediately reached Helmuth von Moltke the Younger, who dismissed him and put in place more aggressive leaders on the field. General Pritwitz had already been previously defeated by General Rennenkampf at the Battle of Gumbinnen, and was a bit wary of facing another defeat against an even larger oncoming force. An attack in both the front and rear would have been devastating to the Eighth Army, which was considered to be outmanned 4-1. By surrounding the much smaller German Eighth Army controlled by General Prittwitz, they could get a decided advantage in the entire area.

The two-pronged attack by General Samsonov and General Rennenkampf included a southwest and northeast attack with the First and Second Army. The invasion was still in the beginning stages and hadn’t really got off the ground, and proved to be one of many failed efforts due to poor planning on Russia’s side. The Battle of El Alamein Russia Backstory Russia suffered a major loss in the Battle of Tannenberg, losing control of its Second Army on August 1914 due to clever planning by German soldiers.
