The Battle of Montebello and Casteggio, 20 Prairial Antoine Charles Horace Vernet (1758-1836)

The picture has something of this: lithograph, water, landscape, people, outdoors, group, architecture, tree, house, town, river, sky, building.
Perhaps it’s a painting of a battle with a large group of men on horseback in the foreground and a castle on the top of a hill in the background.
