Welcome back!
1)My black templars assault squad had routed an imperial guard unit in combat, and the imperial guard unit was positioned, such that their retreat back was blocked by a tank (which belonged to my opponent, but was immobilised), and a wall blocking their retreat to the other side. Essentially there was no way for the squad to run away from my sweeping unit, as their backs were literally against the tank in question. Am I right in thinking that (assuming I had caught them), they should have been destroyed outright? Insetad my opponent moved his unit through the tank to the other side, leaving my unit stranded behind his tank. I'm not sure if this was right, but I let it go at that point. This was to prove crucial later.
Yes, they should have been Destoyed, as per the "Trapped" rules on page 45 of the Rulebook. Models, Friendly or otherwise, are considered Impassible Terrain. Now, if the Tank has been Wrecked, it would have just been terrain, and he can fall back though it fine.
As for the Cities of Death rules, I cannot answer them as I don't have that book :(
