the funniest invasion i've had in EB1.2 happened just yesterday. after capturing the Seleukid capitol of Seleukea and Babilon in a single turn (they were left deffenseless with only 2-4 units guarding them) i stopped all offensive actions against them and decided to camp outside the cities untill i can secure their deffences. after some 15 season i sent one army north and another east. both around 2200-2300 men (mixed composition as always-phalanx,spearmen,archers,skirish infantry and cav as well as lancers) knowing that the AI would avoid counter attacking a full stack at all costs. and then to my great surprise after my eastern army group stopped just as came to a bridge, the seleukid turn was something i've never seen before. 3 succesive counter attacks with stacks numbering 1800, 2600 and 3200 men accordingly. the end result was naturally a total rout for the enemy wit no more then 300 men lost (the bridge crossing tactics) but what surprised me was the AI's initiative. does this happen always when you are inside enemy teritory on a bridge crossing?
