 No forced labour was theoretically imposed; however, drawings made by Slovenian interned Vladimir Lamut show maintenance activities were required.Prisoners were organized following the "Circolare 3C" (Memo 3C) by General Mario Roatta, distinguishing "repressivi" (to repress, partisans) from "protettivi" (to be protected, usually target of Slavic partisans repercussions).In practice, limited resources and frequent influx of new prisoners prevented this separation, causing cohabitation issues.
