The aggressing, Italian army, did not manage to break through the front line in all its eleven attempts. In spite of continuous artillery fire the majority of civilians remained in the region. In October 1917 the Austro-Hungarian and German army set forth from the slopes of Selski vrh, Mengore and Bučenica. They confronted the enemy on the mountain ridge of Kolovrat, where the battle, the key moment of the breakthrough of the Soča front occurred.
