Kanai's unit stopped at a dormitory for Japanese pulp factory workers, and they were given food there. The men of fighting age had almost all been drafted, leaving just women, children and elderly people. The next morning, it was surrounded by Soviet soldiers. Kanai and the others surrendered their weapons, and were led back to the airfield.
What befell the people left at the dormitory after was truly terrible. The Soviet soldiers raped the women, who then killed themselves as a group. The wife and daughter of a worker, who both helped feed Kanai, were among those who took their own lives, he later heard. Atrocities during the war like these, where women were raped and places were sacked, came to be known as "Tonka Incidents," after the area where they took place.
