 In many cases , the opportunity to leave Warsaw came by chance . For example , the hiding diarist Wacław Gluth @-@ Nowowiejski was taken out , after he was accidentally found by a woman ( name unknown ) who had been given permission by the Germans to remove some of her property from the ruins . On their way out of the city the group also had to pass German checkpoints and encountered difficulties similar to those of the <unk> fighters . A Wehrmacht soldier accused the wounded and sick Gluth @-@ Nowowiejski of being a " bandit " but let him pass after protestations made by his escort .
