The Battle of Assurhan (1948)

The Battle of Assurhan (12 July - 24 October 1948) is the single most decisive battle in the entirety of the Great Regional War, widely regarded as the most brutal battle in Acharan history. This battle comprised of a lengthy Aydinirian and Coyteyan defensve against the Allied counteroffensive on Aydinir from the Urus Pass in the very last stage of the war.

The battle began with a vast joint-allied assault on the Aydinirian Empire from Arengin upon recapturing the occupied northern region of the nation in 1947, more specifically, the western assault through the Urus Pass. Vicious fighting took place with air raids, a massive allied invasion, and an equally empowered Aydinirian resistance.

Arenginian troops as well as partisan groups took part in the first assault through the pass. General Usenko Rodionovich and Colonel Kuimov Artemiy Afanasiev were the commanders of the Arenginian forces and with the support of the 4th and 7th Armored Divisions the 3rd and 4th Army groups began the assault on the pass on the 12 of July. The pass had been heavily fortified since the beginning retreat of the Aydiniran occupation forces as resistance began to intensified alongside the strong push of the combined Allies to retake the country. Rodionovick and Adanasiev had anticipated the fortification of the pass by the Aydiniran forces and so they knew that while this took place it was up to Immobilian and Arenginian commandos to begin airborne operations behind enemy lines to disrupt the Aydiniran's ability to fight. While the battle at the pass devolved into a battle of attrition the Carinian commander Tianel Serainao began Operation Gold in which several amphibious assault would take place along the Aydiniran coasts.
