Inside the barracks, built along the Vésubie, there were ten people in the service building, where the families are housed.

There were seven gendarmes there, but also the spouses and a child.

The soldiers, sensing the danger, evacuated everyone.

They found themselves with vehicles and equipment that they were able to save. There, they spent the night organizing rescue missions for the benefit of the population. Most have lost everything except their vocation. "
