This is a dynamic and vivid image portraying a Crusader on horseback, engaged in a siege on a castle. The knight is clad in armor traditional to crusaders, including a surcoat with a cross emblem. The horse is also armored and is captured in mid-gallop, adding to the sense of movement and action.

In the background, a castle looms, and smoke shows the heat of battle, from fire and burning structures. The flag carried by the knight displays the same cross, reaffirming their cause or allegiance. Around the knight, the chaos of battle unfolds with other soldiers engaged in combat. Birds are scattering in the sky, perhaps by the commotion.

The artwork is highly detailed, giving a sense of urgency and intensity to the scene. It captures a moment where the knight is prominently charging forward, leading the attack, indicating leadership and bravery. The artist has used dramatic lighting to emphasize the central figure of the knight and horse, making them the focal point of the scene.
