Are you more likely to have artillery captured in a loss/retreat if it is loose in the stack rather than combined in a division? I think so, and for that reason I always put my artillery in a division, either in empty slots in an infantry division or once I have enough artillery in a stack, in its own artillery division.
On the other hand, perhaps captured artillery lessens hits taken in a retreat somehow - does anybody know?
