The Great Retreat was a Russian retreat from Galicia and Poland during World War I.

Background[]

During this period, the buildup of forces generally favored the Central Powers. Four new German armies, the 11th, 12th, Army of the Niemen and Army of the Bug, were being formed up, dramatically shifting the balance of power in the area, with 13 Central armies facing nine Russian. Under pressure from the Kaiser, Falkenhayn gave in to Hindenburg and Ludendorff's insistence that the offensive be continued.

Stavka decided to start a strategic retreat in order to gain time needed for the massive buildup of war industries at home.

Offensive[]

After the Gorlice–Tarnów Offensive in early June 1915, Mackensen's armies crossed the San River and captured Przemyśl. On 22 June, the Russians left the Galician capital of Lvov. Between June 23 and 27 the Germans crossed the Dniester. In early July, Mackensen had to stop his offensive due to Russian counterattacks.

On 13 July, the Central Powers' armies opened a new offensive across the entire front. Outnumbered and still off-balance due to the earlier actions, the southern end of the Russian line collapsed and started moving northward, retreating to the Ivangorod-Lublin-Chełm line.

More worryingly, the German Tenth and Niemen armies pressed through on the extreme north end of the line, once again leading to the possibility of an encirclement of an entire Russian army.

By 13 July, the entire southern wing had been pushed back another 160 km (99 mi) to the Bug River, leaving only a small portion of Congress Poland in Russian hands, anchored on Warsaw and the Ivangorod fortress. On 22 July, armies of Central Powers crossed the Vistula river. On August, the Russian Fourth army left the Ivangorod fortress. With the continuing Russian retreat, Warsaw became isolated, and the German 12th Army (under Gallwitz) seized the opportunity and conquered it on 4–5 August.

New attacks by the German Eighth, Tenth and Twelfth armies moving south out of Prussia soon caused even this front to collapse, sending the entire northern end of the Russian lines streaming backward, eventually forming a line running north-south at about the pre-war eastern Prussian border.

The Germans, after having received considerable reinforcements, took Brest-Litovsk on 25 August. On 19 September, Hindenburg's forces captured Vilna.

Aftermath[]

At this point, the German advance was finally halted. The frontline now ran from the Baltic Sea to the Romanian border by the Riga-Jakobstadt-Dünaburg-Baranovichi-Pinsk-Dubno-Ternopil line.

On 21 August 1915, Tsar Nicholas II dismissed Grand Duke Nicholas Nikolaevich and took direct control of the army.
