The Russian invasion of East Prussia occurred during the First World War, lasting from August to September 1914. As well as being the natural course for the Russians to take upon the declaration of war with Germany, it was also an attempt to focus German military eyes on the Eastern Front, as opposed to the Western Front, where France was increasingly under the strain of her own German invasion. Despite more than threefold numerical superiority (250,000 Germans against 800,000 Russians)[14] invasion ended with a crushing defeat of the Russian army, Russian losses were 9 times larger than the German.

Plans[edit]

The Germans initially planned to have only the 8th army to act, as they expected that the Russians would be slow to mobilise, leaving Germany to beat France in a few weeks thereby allowing the victorious, battle-hardened German troops to transfer along Germany's superior transport network to fight the Russians on the Eastern Front. This was the basis of the Schlieffen Plan.

However, quite quickly, Russia was able to mobilize an invasion into East Prussia. Any invasion of Prussia was an important blow to German morale as well as her general strategic situation, due to Prussia (including East Prussia) being the historical heart of the German Reich (Empire). The German deployment on the outbreak of the war left only the 10 divisions of the German Eighth Army under General Maximilian von Prittwitz in East Prussia whereas the Russians had been able to mobilize the First Army, under General Paul von Rennenkampf and the Second Army, under General Alexander Samsonov. They entered East Prussia on 7–9 August.

The Battle of Stallupönen, fought between Russian and German armies on 17 August 1914, was the opening battle of World War I on the Eastern Front. It was a minor German success, but did little to upset the Russian timetables.[15]

The Battle of Gumbinnen, started by the Germans on 20 August 1914 was the first major offensive on the Eastern Front during the First World War. Due to the hastiness of the German attack the Russian army emerged victorious. The Germans were forced to retreat, perhaps with the intention of performing holding actions in Mazuria, or even retreating to the River Vistula which would have meant abandoning the salient of East Prussia. This would have fitted in with the plans made before the start of the First World War; that these were the positions the Germans would retreat to if the Russians put up a much stronger fight than they had anticipated. Regardless of whatever preparations had been made, however, it still remained that the Germans could not let the Prussian capital, Königsberg fall into Russian hands. The moral, symbolic and military value (since it was a major military hub) of the city meant to lose it was to invite disaster on the home front, in addition to the strategic ramifications. Also, it was very likely that the Russians would have used the upper hand thus gained to use their superior forces to overwhelm the static German defenses. In short, the Germans had to fight back immediately and force the Russians from East Prussia.

Helmuth von Moltke the Younger, Chief of the German General Staff from 1906 to 1914 replaced Prittwitz with Paul von Hindenburg (brought out of retirement) on 22 August. Hindenburg, along with his Chief of Staff, the formidable Ludendorff would approach the crisis in East Prussia very differently from Prittwitz, who panicked when the Russian onslaught entered East Prussia. In contrast to Prittwitz, Hindenburg and Ludendorff decided to take the offensive and encircle one of the opposing armies. Following the plans of Colonel Max Hoffmann, Prittwitz's deputy chief of operations, they chose to send eight divisions against Samsonov in the Battle of Tannenberg resulting in over 90,000 captured and 70,000 killed or wounded. The Second Army was destroyed and Samsonov shot himself.

In the Battle of the Masurian Lakes, the Germans forced the First Army to retreat out of East Prussia.

The invasion was a ghastly failure for the Russians, a setback which was followed by considerable German advances in the following year, including the capture of the Polish city of Warsaw. However, the crisis caused in the German High Command by the unexpected Russian advance forced the sending of 2 corps and a cavalry division from the Western Front as part of the new 9th Army in order to support the attack on the Russians. These additional forces did not arrive in time for the twin battles, as Ludendorff predicted and, had they entered France as originally planned could have been tremendously helpful to the precarious situation in the West. In the Head of French Intelligence Colonel Dupont's words, "their debacle was one of the elements of our victory."[16][17][18]

Comparison of forces[edit]

The Russians originally had only two armies (1st and 2nd, 19 infantry and 8 cavalry divisions - 400,000 soldiers plus 30,000 sabers, totalling 430,000 men)[19] against the German VIII Army (9 infantry and 1 cavalry divisions- 145,000 soldiers plus 4,000 sabers; totaling less than 150,000 men).[20] [21] [22]

Due to an inferior rail system and the subsequent changing of cars on a different gauge of rail in Germany, Russian mobilization was sluggish, but had gradually built up a considerable surplus of manpower. By the early part of September, the Russians had built up a considerable reserve from the influx of new divisions and corps arriving by rail.

At the same time, the German army had received from the Western Front only two weakened army corps (4 infantry divisions) and 1 cavalry division. Therefore, even with reinforcements and supporting units Germans had no more than 250,000 soldiers.

Despite the complete destruction of the Second Army, before the First Battle of the Masurian Lakes in September, against the Eighth German Army, the Russians had a minimum of 428 infantry battalions.[23] This is equivalent to 27 infantry divisions - more than 560,000 troops, plus more than 250 squadrons of cavalry,;[24] a large number of supporting units - generally much more than 600,000 men; and this despite the losses of 200,000 soldiers in battles of Stallupönen, Gumbinnen and Tannenberg. Therefore, the minimum number of Russian troops against the German VIII Army was at least 800,000 soldiers.
