I think you each made a simple error in the battle for Chang-Sha. If the Shanghai MIL was the remaining 3rd unit subject to the Shatter result, it would have never returned to the map. Well, until possibly in 1945 or so if the Chinese were able to take Shanghai, then it would appear there the next reinforcement phase like long lost magic. But then the Shatter result was converted to a Retreat, so that particular MIL does get to fight again after being pushed back one hex.
I usually hide the Shanghai and Peking MIL in Nanning, which is a very good city for the Japanese to have. When the Japanese finally get close to it, I turn the defense over to other units and just use those 2 units as blocking units on a flank that can't be attacked from more than one hex. And continuously retreat them.
It is one thought to pick the Blitz table for the Chinese to save on unit losses. It is even better to simply retreat before a 3-4 hex attack can even be launched, especially a 4 hex attack, and Chiang was perfectly positioned for that in one of the better areas to deploy him, right along the weather line, with a strong river and mountain line right adjacent for the retreating troops to occupy. But then also most Russian players will fight to the death for Moscow with plenty of lost units, even after the factories rail out.
Yes, this occurred to me about the Shanghai MIL while posting the pic for the AAR. You're exactly right. And good advice about where to put them. Nanning is usually a bit of a backwater and that whole area is hard to attack with rivers and mountains.
re: Changsha. iirc the Chinese in the city were partially flipped so CH would have had to lose 1 unit anyway if retreating. I guess they lost 2 but had a chance to hold the city or cause losses, and weren't sure whether JP would get clear weather to make the attack. Still, it probably would have been a little better move to write off the flipped unit and evacuate an impulse sooner.
