Meeting Between General Nicolas Joseph Maison (1771-1840) and Ibrahim Pasha (1789-1848) Jean Charles Langlois (1789-1870)

The picture has something of this: people, group, many, veil, woman, man, wear, child, herder, mammal, vehicle, military, cavalry, war, recreation.
Perhaps it’s a painting of a group of people in a field with a mountain in the background and a body of water on the other side of the painting.
