During the Juniper wars, the 12th Grenadier Regiment was tasked with holding the flank of the main forces.
However, in the bug-infested marshlands, the crack regiment quickly grew restless, and the colonel decided to rewrite the front slightly, and led his grenadiers through Hillswell Marsh against an enemy of vastly superior numbers. However, the enemy forces consisted mainly of militia, and against the Grenadiers, they were routed with ease.
While this campaign was largely irrelevant in the grander scheme of things, it is widely celebrated by the regiment. Some of the Grenadiers have made their way to the colonies, where their relentless storm will sweep away enemies of the Crown!
