the German's surender

The German's had superior armaments, better position, and more men. The Allies didn't seem to have any artilery, genades, or machine guns, yet they swarmed on the German's. Poor strategy?
The German's camped behind the hill immediately seemed to surrender when a handfull of Allies come over the hill. I thought that was odd. (I know it was a planned trap) But then one guy with a pistol gets dozens more to surrender? Really?
All I could think was that the German's knew the war was coming to an end and were looking for an excuse to surrender. I don't recall troops ever surrendering unless they are totally out-numbered. Seems like they could've easily jumped their few captor's. Yes, you have guns, but there are twenty of us for each of you.
