[9] Under the administration of the Kievan viceroyalty, and the later Chernigov Governorate, Mochalyshche was in the third Stan of Kozeletsky Uyezd; in Yaroslavl Volost [uk].

[11] In 1919, during the Ukrainian War of Independence, a Petliurite insurrection against the White Army broke out in Kozeletsky Uyezd, led by Ataman Romashka Demid Ostapovich [uk].

[12] During this time, an armistice was in effect between the Petliurites and the Red Army, and they co-operated in order to disrupt Denikinite hegemony in Ukraine.

[12] After the White Army was expelled from the region in early 1920, Romashka's forces gained control over Mochalyshche and the rest of southern Kozeletsky Uyezd by resuming the fight against the Soviets.

[12][13][14] During World War II, Mochalyshche was razed as part of Nazi punitive expedition against local partisan activity.
