The division's resistance was described as "heavy",[3] despite the estimate by the 1st Area Army that the 112th was only 35% combat effective.[4] 11 August 1945, a frontal attack by the Soviet armour near Michiang was repulsed. The Hunchun itself was lost to Soviet forces 14 August 1945, after Red Army was forced to send in reinforcements in the form of 386th Rifle Division. Another Soviet attack supported by armour was beaten back 15 August 1945 at Unggidong. Although the next Soviet attack was expected at Pungni-ju city, 16 August 1945 all of the division's units were engaged by Red Army forces simultaneously.[5] The unit was ordered to surrender 18 August 1945 as the part of the general surrender of Japan.
