Map of neighboring countries at the time of Highserk invasion of the Principality of Myard.
46.5. Chapter 46.5
The Highserk Empire army, which started the invasion from three directions, gathered in front of Aidenberg, the capital of the Principality of Myard, while taking over cities on their way.
When the Highserk Empire won the decisive battle with the Myard-Ferrius Union, Highserk annexed Myard into the Empire, except for the Celta territory on the peninsula on Lake Celta.
The Ferrius Kingdom Expeditionary Force, which had been dispatched, was withdrawn back to the Kingdom, but lost the majority due to the fierce pursuit by the Highserk Empire army.
The border fortress, which had been greatly pulled out of the garrison, fell without functioning fully, and the southern territory of Ferrius Kingdom was occupied by the Highserk Empire.
Then, a counterattack by the Four-Country Alliance began. The main force of the Alliance forces invaded the former territory of the Principality of Myard by land from Ferrius Kingdom. In addition to the attack by Liberitoa, a harassment attack by the Myard Navy was coming from Lake Celta.
The Highserk Empire abandoned the occupied territory of the Ferius Kingdom, and while devoting their army to delaying tactics, strengthened the defense at Sarajevo Fortress at the border of Myard and aimed for attrition warfare.
Due to repeated exhaustion and deadly surprise attacks, the Four-Country Alliance abandoned the capture of Sarajevo fortress and shifted to the scorched earth tactics of the Demon Territory using black water from Liberitoa Trade Federation.
