Second Battle of Othii Pass

The Second Battle of Othii Pass was a battle between Fire Nation forces and the Spirit Wilds during the Spirit War. It was a significant Fire Nation victory, dislodging the Spirits from their offensive momentum into Fire Nation territory, and was fought at tremendous cost for both sides. It was significant for drawing upon the entire stretch of the Fire Nation's network of vassals, as Even Newer Mexico and Duchy of Yorktown forces both played a significant impact on the outcome of the battle, as well as the first combat encounter of Even Newer Mexican Auxiliaries. As of October 2022, the battle is the largest to have happened in history, with somewhere in the ballpark of 500,000 combatants taking the field.
