The story of the twenty-nine months of fighting for positions along the Soča ends in the Black Room, a room of warning. Portraits of soldiers at prayer before they were sent into battle, the gate of the Italian military prison, crucifixes and sculptures made by soldiers who mourned at the graves of their fallen comrades, a gun carriage amid the rubble of stone and twisted iron, and above them photographs of the horrors of war all tell of the senselessness that went on in the mountains around the captured Mount Krn for full twenty-eight months.

All the subsequent assaults by Italian troops against the well-fortified Austro-Hungarian positions were unsuccessful.

Their retreats to their starting position brought only reports of terrible losses on the battlefield. The building that today houses the Museum was occupied by Italian military court.
