An Encampment in St. James Park Paul Sandby (1725-1809)

The picture has something of this: people, tent, group, landscape, camel, cavalry, man, desert, war, battle, mammal, house, dust, transportation system, street, soldier, campsite.
Perhaps it’s a painting of a group of people standing in front of a tent with a horse and carriage in the foreground and a castle in the background.
