Battle of Lion Run

Fought more or less concurrently with the Battle of 14 Nations, the Battle of Lion Run was a major decisive victory early in The Tharrisian War for the allies against Tharrisia. 
With the deceleration of war against Tharrisia, Tharrisia soon organized an invasion force against Aurelia to hopefully keep Aurelian attention away from other theaters of war and potentially threaten Starmont Allod and the seat of power of The Wayfarers themselves. 
Banking on Embrel being too worried about their eastern border to be able to prepare a response, four legions under the command of Legate Pompenias marched towards the Aurelian border. They were met in battle by an Aurelian Army led by Evoda Vitri and Zelena Stellings.
The two armies engaged each other about three miles into Aurelian territory. The Aurelian's fought the legions to a surprising standstill. But it was clear that a protracted campaign would lead to widespread devastation as Tharrisian reinforcements would arrive far before Aurelian reinforcements would.
Luckily for Aurelia, a reinforcing force of Embrellian Knights and cavalry arrived, led by Torva'Kir Eirnon. The cavalry force smashed into the legions and forced a retreat. While not a devastating defeat, it was enough of one to give Tharrisia pause before invading again, and thus gave Aurelia time to bring up reinforcements.

The Conflict

Outcome

The loss of the battle gave the Tharrisian's pause before planning a secondary invasion, and it gave plenty of time for Aurelia to bring up further reinforcements from its more northern territory, avoiding the possibility of a sudden rush of Tharrisian legions in their southern most territory. 
The battle also coincided with the Battle of 14 Nations, which would be a major turning point in the war on its own, but most historians agree that had the Battle of Lion Run turned into a protracted siege of Starmont, it would've greatly damaged Aurelian military capabilities and morale for the rest of the war.
