In early 1941, almost all the Poles and Spaniards, except for a small group of specialists working in the quarry's stone mill, were transferred from Mauthausen to Gusen.
Začiatkom roku 1941 presunuli takmer všetkých Poliakov a Španielov, okrem malých skupín špecialistov pracujúcich v kameňolome, z Mauthausenu do Gusenu.
