Strategic Narrative Overview
On the night of 10–11 May 1918, German Imperial Army forces, including the 28th Landwehr Brigade under General Franz Hermann Zierold, attacked the Polish II Corps near Kaniv. The Polish forces, commanded by General Józef Haller von Hallenburg and including Brigade II of the Polish Legions, were caught at a significant disadvantage. The Germans pressed their assault through the night, overwhelming Polish defensive positions and breaking the corps' cohesion.
01 / The Origins
Following the Treaty of Brest-Litovsk in March 1918, German forces moved to consolidate control over formerly Russian-held territories in Ukraine. The Polish II Corps in Russia, composed of Polish soldiers who had served on the Eastern Front, found itself isolated in this new geopolitical landscape. Tensions rose as German and Austro-Hungarian forces sought to disarm or neutralize Polish units that remained armed and unaffiliated with the new German-aligned order in Ukraine.
03 / The Outcome
The battle ended in a decisive German victory. Approximately half of the Polish II Corps' soldiers surrendered to German forces, while the remainder retreated in disorder. General Haller himself managed to escape and eventually made his way to France, where he later commanded the Polish Blue Army. The engagement effectively ended organized Polish military resistance in that region of the Eastern Front.
