|Before the kobalds attack.|
The bowmen in 3502 and 3602 fire at Warth, seeing him push his way into the front. One hits for 3 damage. Warth isn't stunned.
The white striped kobald fires at Andrej. He manages to just hit AC 2 - his arrow careens off Andrej's shield, causing no damage.
The kobald swords attack. The kobald in 3103 steps forward and attacks Andrej from the rear, gaining a +1 to hit; he succeeds in landing his blow, just, and Andrej takes 3 damage.
The kobald in 3404 runs into 3405, grabs his sword and attacks Ahmet. He rolls a natural 20, hitting AC 0. (GCI: for a 20 to be "critical," it must be 2 or more above the number needed to hit. The kobald here needs a 19 to hit Ahmet, so the 20 isn't double-damage; those times in this combat when I have doubled the damage on either Ahmet or Andrej, it was because the kobald got a bonus +1 for position or personal strength. There's no bonus here, so the damage is not doubled). Ahmet takes 1 damage.
The kobald in 3203 attacks Zoft, hitting and causing 5 damage. Zoft doesn't have the hit points and is stunned, falling back into 3404.
Finally, Warth is attacked from 3604. He's hit for 1 damage. This doesn't stun him.
Here is the position after the kobalds attack:
