In late 297, the Shield fought the Shattered Spear during their grueling march towards Heaton, the last city to be liberated.
The many trees and the vertical coverage of the Heaton Vale allowed Amadeus Sinask to use an effective strategy against the hordes of Shattered Spear warriors in their way. By continuously drawing out enemy troops and falling back, his archers, many trained hunters from all over Erenen, were able to weaken the Shattered Spear forces to such a degree that they were forced to fall back to Heaton itself, leading to the First Siege of Heaton.
