Croquet at Boulogne Édouard Manet (1832-1883)

The picture has something of this: people, woman, wear, group, veil, man, child, two, girl, three, war, recreation, outfit, four, weapon, lid, family, military.
Perhaps it’s a painting of a group of people standing next to each other in a field with a dog on a leash in the foreground and a lighthouse in the background.
