Heinrich Himmler speaks to a meeting of the commandants of all the concentration camps in Occupied Poland, telling them that the plan is to use Poles as workers then they will be exterminated.
As Himmler explains:
"...all skilled workers of Polish background are to be used in our war industry. Afterwards, Poles will disappear from the world. ...
Every German's time is coming. That is why it is necessary for the great German people to see their main task in the destruction of all Poles."
