With help from the Volcanian Navy, Nakh's 1st Expeditionary Army performs a tri-flank encirclement on a quarter of Aurelia's forces, using superior force concentration to pierce through the gap in Aurelia's lines and going through the completely bare backlines of Aurelia, arming guerilla units with weapons captured from the encircled unit, which is no longer capable of offense, and using overwhelming support from civilians to blend in, hide in places Aurelian forces can't reach using the people's knowledge of the land, rat out nearby locations of Aurelian forces, and further the cause of independence, while Nakh forces resupply ammunition off of the corpses of the Aurelians. Chemical warfare, by now, has proven to be ineffective at anything but radicalizing civilians against Aurelia. Additionally, a second expeditionary army is being prepared.
the unit in red is incapable of offense due to supply being cut off, which means it's basically a sitting duck
