I checked the Civilopedia, but it contained not enough information to answer my concrete question. BTW, is there any general thread explaining the whole healing issue?
And now my concrete question... Round1, my enemie has a settler and a spearman and wants to settle right there. A stack of barb warriors ist threatening him, but his spearman survives the brawl with the barbs and is promoted to elite, 3 HPs remaining.
Round2, he fortifies his spearman an settles at the same place.
Round3, the spearman has recreated completely.
I was quite sure, he would have given back only 1 additional HP back, not 2 of them.
It's an MP (PBEM), may be rules differ a little bit to single player games?
