Wellington (1769-1852) at Sorauren, 27th July 1813 Thomas Jones Barker (1815-1882)

The picture has something of this: people, mountain, group, snow, man, exploration, rock, landscape, recreation, ice, woman, adventure, expedition, water, two, climb, valley.
Perhaps it’s a painting of a man riding on the back of a white horse next to a group of men.
