I started reading through "Desert Victory" by Julian Thompson. Its a collection of firsthand accounts of the war in North Africa. I came across this good story in it:
Captain Hans-Otto Behrendt, aide to General Rommel:
On the way back to Derna we encountered a British soldier with a broken-down motorbike and when we drove up, he asked us if we were going to the 3rd Armored Brigade, and I said 'yes'.
He got into my car, and after a while he said 'strange car'.
'Yes, you are right, this is a German car, and we are Germans', I replied.
All he said was 'Oh'.
I admired him for his coolness.
This alone was worth the price of the book.
