Continuity mistake: When Cpt. Nixon is running out of booze while he is playing poker with some other officers he is going out to take a walk. After a while he stops in front of a shop window and smashes a petrol can from a nearby jeep through the glass. There is a big hole in the window but not big enough for him to get through. Two shots later there is no glass at all in the shop window even though he never had the time to remove the rest of it.
Factual error: At the beginning of the episode it says is April 11, 1945, the men are listening to the 4 piece then it goes to a month earlier. At the end of the episode, it returns to this exact scene where Nixon announces, "Hitler is dead." Hitler didn't commit suicide until ten days after his birthday, the 20th, on April 30.
