A German Propaganda truck at the border to France in 1939, shortly after the French declaration of war towards Germany. The Germans sent over messages such as 'Why do you fight us?' or 'We won't shoot first!'. This was mainly to delay the French while Hitler had to delay the Invasion of France because of the higher than expected losses in Poland.

German Propaganda Truck

German SS troops during their march into Amsterdam in 1940. Oddly enough, the people were cheering, which I have a hard time understanding, considering their country was just invaded for no reason at all... On the other hand, they were also cheering when the Allies arrived, so I guess they're just polite people (Bundesarchiv, Bild_183-L23001)

German March into Amsterdam

German Wehrmacht troops during their march into Athens. When you look at the soldiers you can tell that they had already gone through some fierce fighting, as there were some strong Greek defenses along their way. Also, notice the lack of people cheering compared to Amsterdam.
