On 18 April the II Corps was ordered by the Regency Council to stop near Kaniv in Ukraine; in a triangle between Potik, Kozyn and Stepantsi. Soon it begun to be surrounded by a nearby German units. On 6 May the commander of the 28th German Landwehr Brigade, General Zierold, subordinate of Marshal Hermann von Eichhorn, issued an ultimatum to the II Corps, demanding it lay down its arms and surrender. II Corps readied for battle, and surprised Zierold, who was unprepared for battle. Zierold backed down saying that the ultimatum was a miscommunication. Soon however Zierold received reinforcements, which convinced him he had enough strength to force the issue. On the night of the tenth of May to the eleventh of May 1918, II Corps was surrounded and attacked by German units. Polish units, initially surprised, formed on the village of Yemchykha and took defensive positions. The II Corps resisted for about a day, and both sides sustained heavy losses. By the evening of 11 May the Germans, who did not expect the Poles to put such a stiff resistance, proposed a ceasefire and negotiations. With supplies running low the Poles accepted the offer to negotiate, and eventually agreed to an honorable capitulation. The battle resulted in heavy losses for the Germans, estimated at about 1,500 dead and 273 wounded. Polish losses are estimated to be much smaller, at about few dozen killed and about 150 wounded. Half of the Polish survivors were arrested and sent to prisoner of war camps (number of prisoners is estimated at about 3,250; another estimate suggests 4,000 imprisoned, and 1,500-2,000 who escaped), but the others managed to escape. Those who escaped included the Polish commander Józef Haller de Hallenburg, who faked his death in the battle, and fled to France where he was later appointed commander of the new Polish unit, the Blue Army (or Haller's Army). In the Second Polish Republic, several units would adopt the name "of Kaniów" in honor of that battle: the 28th, 29th, 30th and 31st Infantry Regiments (of Kaniów Rifleman, Polish: Pułki Strzelców Kaniowskich") and 6th Uhlan Kaniów Regiment (6 Pułk Ułanów Kaniowskich).
The Revolt of the Czechoslovak Legion was the armed actions of the Czechoslovak Legions in the Russian Civil War against Bolshevik authorities during May - August, 1918, in Volga, Siberia and Ural regions.
