Conversation so far:
What started the Midsummer crisis of 1941?
King in a private conversation had threatened to abdicate if the Government did not approve a German request to transfer a fighting infantry division .
What was the outcome?
"Most Urgent-Top Secret" message to Berlin in which he stated that the King had just informed him that the transit of German troops would be allowed.

Question: Why was this agreed upon?
Self-contained rewrite: Why did Sweden agree to allow the transit of German Troops?
