There were also other immense difficulties during the Aktionen as the Jews tried to avoid evacuation by all possible means. They not only tried to escape, and concealed themselves in the most improbable places, drainage canals, chimneys, even in sewage pits, etc. They barricaded themselves in catacombs of passages, in cellars made into bunkers, in holes in the earth, in cunningly contrived hiding places, in attics and sheds, inside furniture, etc. As the number of Jews still remaining decreased their resistance became the greater. They used weapons of all types for their defense, and in particular those of Italian origin.
