There are no units in the fog between Saladin's city and our own.
Clever idea about gifting the beleaguered city to Cyrus! That wouldn't have occurred to me.
As for promotions, I would hold off. Unless you plan to removed the chariot with them... maybe not a bad idea.
We will likely lose one, but that still leaves a second archer to perform guard duty. I would check the odds first - if they're over 85%, I'd save the promotion. Under 85%, and I give combat1.
