The 1915 Great Retreat: How Russia Abandoned Its Polish Salient to Survive

History · Published 3 October 2026 Swipe more like this →

In short: In 1915, the Imperial Russian Army faced a catastrophic collapse under the weight of a massive Central Powers offensive. To avoid total encirclement, the Tsar’s forces executed a desperate, scorched-earth withdrawal across Poland and Galicia, permanently altering the Eastern Front and triggering a brutal humanitarian crisis within the empire.

The Great Retreat was a strategic response to the Central Powers' summer offensive of 1915. Following the success of the Gorlice–Tarnów offensive, German and Austro-Hungarian commanders, including Erich von Falkenhayn and August von Mackensen, launched a multi-pronged assault aimed at forcing a decisive battle. By late June, Tsar Nicholas II and his senior leaders at Baranovichi decided to abandon the vulnerable Polish salient to shorten their front lines.

The retreat was marked by intense combat and logistical chaos. As the Russian army fell back, they devastated border territories, forcibly deporting 500,000 Jews and 250,000 Germans into the interior, driven by military leadership that viewed these groups as potential spies. The scale of the loss was staggering; in just 45 days, the Russian army suffered up to 1,006,000 casualties, with the number of prisoners taken by the Central Powers exceeding 511,000. The surrender of the Novogeorgievsk fortress alone accounted for nearly 90,000 of these captives.

The retreat also exposed deep fractures within the Russian military. Discipline plummeted, with reports of mass desertions and soldiers inflicting self-mutilation to escape the front. By September 5, 1915, the Tsar assumed personal command, dismissing Grand Duke Nikolai and ordering an end to the withdrawal. While the front eventually stabilized, the offensive had achieved its strategic goal: the Central Powers, having inflicted heavy damage, shifted to a defensive posture, confident that Russia posed no immediate threat.
