Sometimes, you have a city pushed out a bit too far and an opponent Civ is just going to take it no matter what you do. I'm embarrassed to even say this after years of play, but I just realized the only thing to do. Build (or have) a transport to take the units to a safe city (and rehome them) and sell the best city construct you have for the cash. I know, I know, you should always have your cities fortified enough, but sometimes there are surprises.
I captured Leonardo's in an opposing Civ city (I just LOVE Leonardo) and I extended too far. And was worth it, too (massive upgrades for 3 turms). But I couldn't hold it. Staring at the screen for some way to hold it, I suddenly realized I had gotten a lot but would lose a lot fighting to keep it. So I emptied the city units onto a transport "just" in reach of one of my better cities. And sold the library I had captured. Survived there a 2nd turn (gotta love the City Walls) and sold the barracks.
Saved units and got $200 gold.
All that may be obvious to some of you, but it wasn't to me. So I wanted to pass it on "just in case"...
