What were the Germans thinking when they heard about the invasion of Poland on 1 September 1939?

So many questions:<br><br>- How did they feel about the war? Did they support it? <br>- Did they expect it to happen?<br>- Did they expect a wider war to happen?<br>- Did they know about the Molotov-Ribbentrop Pact?<br>- Were they concerned about the state of their military (it obviously turned out to be quite good, but in 1939 did they KNOW?) or their economy?<br>- How did they feel about their neighbours in general? France and the UK in particular, but also other European powers like Italy and the USSR as well.
