Iron Man technically won in the comics, because Captain was killed by a brainwashed Sharon Carter.

Hush my child, I know it's all very confusing.

but didn't cap surrender after seeing the destruction?

He did, and he was brought in. While being transferred from the vehicle, Crossbones shot at him from a helicopter but the killing shot was dealt by Sharon Carter.

It's from the comic, Captain America: The Death Of The Dream, in case you were wondering.
