Pretty much. I really thought I was going to get owned, but those Praetorian fellows miraculously turned over the battle. Or phreaps the enemy army was already exhausted. That'd explain how those Praetorians Cohorts managed to put everyone running away. This battle didn't really change much in my campaign, at least immediatly. The Egyptian armies managed to erase my army directed to take Alexandria and another one on the way of Siwa to help Memphis. They reached as far as besieging 3 units defended Siwa with a full stack, though (Thanks to RTW AI) they retreated from besieging it, and basically spent their time fighting my armies in Egypt and later in Sinai. But yeah, I did raze some cities to the ground in RTR when I was being attacked by three factions and one of them was Uber-Macedonia. In EB, I still haven't got in a situation where I needed to destroy everything.
