Most vassals were enthused about fighting in these wars What would you have been thinking during this battle?

As a vassal in battle, I would likely feel a mix of duty and anxiety. The pressure to demonstrate loyalty to my lord and defend our territory would weigh heavily on me, but the chaos and violence of war could also evoke fear for my own life and the lives of my comrades. The desire for glory and the hope of rewards might motivate me, yet I would also be acutely aware of the potential consequences of defeat. Ultimately, I would be focused on survival and the camaraderie of my fellow soldiers amidst the turmoil.
