The panic was there, but the deeper ranks were alerted to the assault and had prepared. (So the current layout is in a three-way zone. You're attacking from the southwest corridor, and the chaos is assaulting the south gate, which is to the current north of them.) Performing a rapid battlefield rotation, the ranks of long range units swapped places with Khorne berzerkers, who didn't hesitate to attack the legionnaires in melee, and with overwhelming strength. The battle had, for now, stabilized again for the chaos assault, as the majority of their reinforcements were coming from the southeast corridor. Even with someone like Ariel with them, the battle was difficult. However, things quickly began to change as the chaos forces were now being attacked from their reinforcement corridor, cutting them off into a less than fortunate position.
