Miquel Bosquet i Folqué, Eugeni Riera i Moll, Josep Alcoberro i Solé and Jesús del Pueblo i Moreno all suffered the cruelty of Nazi extermination camps. All four were Barcelona firefighters who during the Francoist period had to go into exile in France and who ended up as prisoners of the Nazis.

Miquel Bosquet i Folqué (1905-1941) joined the Barcelona corps in 1936 and was called up to fight for the Republican side two years later. After the Civil War he went into exile in France, where he was detained in 1940 and deported to Mauthausen and Gusen. He died in 1941.

Eugeni Riera i Moll (1895-1941) became a firefighter in 1917 and was a senior in the corps when he went into exile in 1939. A year later he was detained and deported to a prison camp in Strasburg. He was later sent to Mauthausen, where he died at the age of 45.

Josep Alcoberro i Solé and Jesús del Pueblo Moreno survived the Nazi camps and were freed in 1945. Alcoberro was born in 1907 and joined the corps in 1936. Like the rest, he went into exile in France three years later, where he was detained and later sent to Mauthausen. Del Pueblo, who also joined the Barcelona corps in 1936, survived Auschwitz and Mauthausen.

Now all four have been remembered with a commemorative plaque in their name in the entrance to the Espai Bombers. The plaque is an act of recognition by the Barcelona Fire Service in collaboration with the organisation Amical de Mauthausen and the participation of relatives of the firefighters.

An estimated 100,000 Catalans went into exile during the Francoist years, with nearly 2,000 detained and deported to Nazi concentration camps. Firefighters who stood out for their democratic ideas, left-wing, republican, anarchist or pro-Catalan perspectives also had to go into exile to escape fascism. Many who headed for France ended up in German concentration camps such as Gusen and Mauthausen.
