Directorate of Ukraine
In early 1919, the Eastern Front of the Directorate of Ukraine collapsed, and by spring, the Ukrainian insurrection had failed under attack from all sides, including by the White armies. In the summer of 1919, after the Polish successes in several skirmishes with the Bolsheviks, both combatants were engaged on multiple fronts, were near the limits of their capability to wage war against each other and needed time to regroup and to concentrate their forces.
