The outbreak of World War II altered the role of the BDM, though not as radically as it did the role of the boys in the HJ, who were to be fed into the German Wehrmacht (armed forces) when they turned 18. The BDM were told by their leaders during the invasion of Poland that the Poles were a people "worthy of disgust, genuine sub-humans, who deserved to be ruled by a master race." The BDM helped the war effort in many ways. Younger girls collected donations of money, as well as goods such as clothing or old newspapers for the Winter Relief and other Nazi charitable organizations. Many groups, particularly BDM choirs and musical groups, visited wounded soldiers at hospitals or sent care packages to the front. Girls knitted socks, grew gardens, and engaged in similar tasks.
