This is a sepia-toned drawing or sketch depicting a scene from the American Civil War. The central figure is a man in a Union Army uniform, seated on a horse. He wears a tall, cylindrical hat with a brim, and his uniform is adorned with buttons. The horse is depicted in profile, with a detailed head and neck. Behind the man and horse, there are several other figures on horseback, partially obscured by the composition. The background suggests a landscape with rolling hills or a wooded area. At the top of the image, the number '49' is written in pencil. Below the scene, there is a handwritten inscription in German: 'Wie der Vollmond in Tennessee aufgeht! 1862.' which translates to 'As the full moon rises in Tennessee! 1862.' The drawing is executed in a loose, sketchy style, with visible pencil strokes and shading. The overall impression is one of immediacy and historical documentation.
