I personally refer to them as the "Three Patriots".
The painting takes place in the Revolutionary War, and in the painting we see three people, a young drummer boy on the left side, an older man drumming in the middle, and a man bearded man with a bandage on his head playing the flute.
The three appear to be marching on the aftermath of a battle and in front of them is a wounded man laying on a broken wheel. Behind them is smoke clearing and the American flag flying behind them and soldiers following them.
Who was the painter also?
