Louis Francois Lejeune – Battle of the Pyramids, 21 July 1798 Château de Versailles

The picture has something of this: tree, water, nature, outdoors, beach, landscape, palm, sky, seashore, dawn, sunset, tropical, vacation, daylight, sun, scenic, sand.
Perhaps it’s a painting of a war scene with a large amount of smoke coming out of the sky and a large group of people on the other side of the scene.
