Bombing of Warsaw in 1939.. goals?

[Kurfürst]

Dear Gentlemen,

I am looking for factuality behind the various Luftwaffe bombings of Warsaw in the Polish campaign in 1939, more precisly, I wish to know the intended nature of those attacks, preferably while relying on German sources and not contemporary press/post war authors influenced material.

Was spreading terror considered a goal by the planners back them, were targets specified in order to achieve this, or the terror bombing version is influenced by contemporary and post-war press?

This is understandibly a sensitive subject, that's why I am inquiring about it here, where we have so many cool heads and lots of papers to work from around.

So, what is the picture of the nature of these bombings from September 1939 German documentation, orders etc?

TIA!
