Invasion of Dunay Bay

The Invasion of Dunay Bay is the event that sparked the War of the Weary. The Setupit Empire under the ambitious leader Mahertian II, invades Dunay Bay, a territory that had been annexed by the Russius Empire in the Suna-Russius Expansions. Though it is mostly populated by ethnic minorities within Russius, the area is strategic to the Russius Empire as a port. It took place in 0 AD.

Prelude
Having failed an invasion of Korean kingdoms Baekje and Silla, the empire of Setupit chose to invade the state of Dalner, a state that had been conquered by Russius, resulting in a majority of its populace having negative opinion of the Russius Empire.

Invasion
An estimated two hundred ships sailed across the Sea of Japan, landing more than twenty thousand men on the ports of Dunay. The Setupit army confiscated every ship in the bay, and forced its people to pay homage to the Emperor. While the invasion was met with mostly no resistance, a Russius merchant refused to surrender his ship to the invading force, leading to a small skirmish.

Aftermath
The invasion was successful for the Setupit Empire, as they captured a vital foothold that connected mainland Japan with its new dominion. News of the invasion alerted other towns, spreading from one to the other until word reached Riverdale. Diplomatic actions were taken, but tensions were too high and communications between the two distinct nations was poor. The very next day Russius and Suna formally declared war on the Setupit Empire, beginning the War of the Weary.
