Field Report: Vicount Antrim Victorious?

 

Our Isekaied/Reincarnated hero is victorious having engaged twenty thousand of the Empire's elite soldiers in combat and forced the Imperial Commander to flee the field.

Despite an army of Magic-users, Archers, and Cavalry, the Empire was ill equipped to deal with trench warfare involving barbed wire, flame throwers, and exploding metal spheres hurled by Trebuchet.

Of course failure comes at a price...
