The suicidal generals are rediculous so I've generally never fought with more than one stack. This morning I broke that rule. I attacked a beseiging Jullii army with a small, but powerful, stack containing a 5 star general. The city forces were more numerous (comparable to the romans) and included a family member as well.

I was forced to attack with the small stack vs the city force cos I didnt want my 5 star to 'light brigade' the cohorts. Being heavily outnumbered with my small stack, I waited for the city force to move forward and engaged the Jullii simultaneously. Within 1 min my city commander was dead. Although I won the battle and slaughtered the romans, I took much heavier losses than if I had not moved my 5 star stack to support, and simply sallied forth with my city force
