Troyon Constant LA VALLEE Constant Troyon (1810-1865)

The picture has something of this: mammal, tree, people, outdoors, cavalry, cattle, group, daylight, landscape, two, wildlife, backlit, livestock, water, sheep, skirmish.
Perhaps it’s a painting of a herd of sheep on a dirt road with a hay bail in the foreground and people on a horse drawn carriage in the background.
