The Dawn of Victory (Lord Clyde Reconnoitring the Position of the Enemy, in Advance of the Relief of Lucknow) Thomas Jones Barker (1815-1882)

The picture has something of this: cavalry, mammal, people, group, water, two, recreation, herder, seated, man, daylight, outdoors, woman, landscape, three, winter, tree.
Perhaps it’s a painting of a group of men riding on the backs of horses in a field near a body of water with a cloudy sky in the background.
