A
fascist came to the hospital pretending to be a partisan in distress, in order to obtain evidence to denounce and accuse him. As a result, Barzotto was
arrested in the hospital by the Black Brigades and taken directly to the
Casermette, where he was repeatedly
tortured for at least two weeks. On 3 November 1944 he was imprisoned in the Pordenone jail (inmate no. 2329), and on 18 November he was transferred to the Udine prison, where he awaited execution by firing squad or deportation.
In Udine he managed to meet his father briefly, who had been arrested on 16 December in the Friulian town, before being loaded onto a transport bound for
Flossenbürg; Bruno, instead, was put onto a cattle car bound for
Dachau. Bruno Barzotto returned from the
Dachau extermination camp suffering from tuberculosis, from which he died on 18 September 1947.
He managed to write down his memories of deportation, leaving a vivid testimony of those terrible months.
