Although there were sufficient lifeboats for the entire ship's complement, including the Italian prisoners, heavy listing prevented half from being launched until the vessel had settled. The prisoners were abandoned in the locked cargo holds as the ship sank, but most managed to escape by breaking down hatches or climbing up ventilation shafts. Several were shot when a group of prisoners rushed a lifeboat, and a large number were bayoneted to death to prevent their boarding of one of the few lifeboats available. The Polish guards were armed with rifles with fixed bayonets; however, they were not loaded and the guards carried no ammunition. Witnesses indicate that few of the prisoners were shot. Instead, most of the casualties were bayoneted.
