Battle of Bongo-dong

Hong Beom-do’s Korean Independence Army, joined by Choe Jin-dong’s and An Mu’s units, lured Japanese troops into the Bongo-dong valley and routed them.

After the March First Movement, independence units in Manchuria raided across the Tumen. When Japanese troops crossed the river in pursuit, the allied forces, organized as the Northern Military Command, ambushed them at Bongo-dong on 7 June 1920. The Provisional Government’s war ministry announced 157 Japanese dead.

The first major victory of the independence armies over Japanese regulars, it greatly lifted morale, and Japan looked for a pretext to send a large army into Manchuria in revenge.
