"On december 5 1942 in Auschwitz-Birkenau, after the round-call of the morning, which was atrocious since you would need to stand still for hours until the count matches, the SS took the entirety of the women camp moved them in front of a ditch within the camp and asked the 6000 present alive women to get naked.

Then, the SS armed with whips, pistols and canes got over the ditch, made two parallels lines to create some sort of corridor. Then they screamed the women prisonners to jump over the ditch and run through the corridor of SS soldiers.

During the run, the SS with the whips and cane struck/whipped/pulled away all the women they deemed "unfit for labor" due to sickness and physicall exhaustion. Out of the 6000 women that day, around 1500 made it to the end of the corridor without being pulled away : They were the lucky ones and the camp commandant made a speech sort of like "You were chosen to live".

The 4500 women pulled away by the SS or who couldn't jump far enough to pass the ditch were pushed into trucks and send to the gas chamber. They apparently screamed like banshees full knowing they were sent to their death.

Very few women survived from 1942 to 1945 in auschwitz, but the detail of this day is present in the few books/testimonies from survivors because of how horrible it was."
