I am communicating with ardent enthusiast regarding this dynasty via e-mail, due to his connectivity issues, and I will relay his orders and comments here, for the benefit of his men and others.
Currently, he has no new orders for his men. Since Zone 4 seems to be pretty well in hand, he is willing to "loan out" his 81mm mortars to someone else who feels the particular need for more fire support (Hint hint Blade6119).
