Dunden War

The Dunden War was a conflict that raged from 266 AC to 269 AC in the tiny nation of Dunden, south of the Regalian Empire in a continent known as Southwynd. Dunden was the last independent nation not subject to the Regalian Empire on the western half of Southwynd, and since the Kingdom of Myre had just been subjugated two years prior, the Empire felt confident that the much weaker Dunden would be easy to defeat. The Dunden War was however a quagmire for the Regalian Military, as the Perrion War had only just concluded, and much of Regalia's military command was exhausted from that war. Veterans who had survived the Perrion War were re-deployed to Dunden, a poor and infertile land of rocky crags and mountains, where ships could not deliver supplies due to the many shallow outcrops of rock among the islands. The fighting was particularly brutal around the mountains, where the local Dunden used rockslides to kill Regalian patrols and soldiers. While the Regalian Empire had fought formal wars with pitched battlefields for centuries, the Dunden war was the first real guerilla war, something Regalia's military was incapable of dealing with, a problem that would haunt them later in the Ramon War. Dunden eventually surrendered when their hillforts were all captured and the war concluded in three years, which was still relatively short. With the conquest of Dunden, the Regalian Empire for the first time touched the borders of the Essa Empire to the south, and friction started almost immediately over a series of islands that were part of Essa, but were claimed by the Dunden and subsequently Regalia. This would later inform much of the prelude to the Chrysant War.
