You are corret here partly.
You see the difference in the meanings CAPTURE and GIVING UP.
Stalingrad was CAPTURED, but never GIVEN UP, there were troops that were resupplyed from USSR east.
I guess you just have a different definition of captured from me. To me, the word captured means seizing something and you have full control of it. Take it this way. Let's say there was a robbery suspect that the police are chasing. Then suddenly, a police officer yelled over the radio, "I HAVE FINALLY CAPTURED THE SUBJECT!" And the rest of the police officers replied over the radio, "Great! did you have a hard time capturing him?"
Then the officer who "captured" the suspect replied, "Well....he's still punching and kicking me, trying to get away."
