Nah, I'd just switch my oath to Markianos so he could keep his army.
Noone's taken your army, it's sitting right there in the stack with Kalameteros. I'm not sure which units are Kalameteros' and which are Hypatios', but about 30 seconds of talking to deguerra would clear it up if you are so against having Hypatios or his PA involved in the assault on Iconium.
