The advance of the division towards Jiamusi was stymied by formidable Japanese opposition south of Xingshanzhen, which was outflanked by a 14 August amphibious landing of the 83rd Rifle Regiment of the 34th and another regiment from the 361st Division by ships of the Amur Flotilla near Huachuan on the Sungari, 40 kilometers north of Jiamusi.
