Akiba drummer requested others to recite the Kaddish on his behalf. They agreed to do it within three days and would remember him when they see the smoke rise from the chimney. He headed towards the hospital and didn't look back, anticipating his arrival at Birkenau. Despite the hardships, they forgot to say the Kaddish within the agreed timeframe.
