in her novel "das schlafende heer" ("the dormant army" or "the sleeping army"), published in 1903, viebig praised conquest of polish territories by german settlers and warned of "dangers" posed by polish minority in germany, which she characterised as "disloyal" and "uncultured". left unchecked, she warned, poles would overwhelm germany and thus need to be controlled, repressed and assimilated. viebig's viewpoint was characteristic of german attitudes at the time, and her work formed part of the german heimatkunst (regionalism) literary movement during this period. this novel became a bestseller in german empire in 1904 and 1905, and, besides "die wacht am rhein", was her most read novel.
