The Relief of Ladysmith on 27th February 1900 John Henry Frederick Bacon (1868-1914)

The picture has something of this: people, group, many, cavalry, military, man, soldier, wear, mammal, war, weapon, veil, skirmish, woman, crowd, group together, outfit, army, uniform.
Perhaps it’s a painting of a group of people riding on the backs of horses in front of a crowd of people standing on the side of a dirt road.
