Peasants Lunching in a Field Daniel Ridgway Knight (1839-1924)

The picture has something of this: people, group, man, military, war, skirmish, outdoors, soldier, tent, weapon, woman, army, desert, group together, gun, mammal, landscape, wear.
Perhaps it’s a painting of a group of people sitting and standing in a field with hay bales on the ground and a person holding an umbrella in the foreground.
