The image shows a group of people dressed in red uniforms and hats, engaged in a reenactment. They are standing in front of a large white tent with a blue dome on top. The tent is set up on a grassy field with trees in the background. In the center of the image, there is a man holding a rifle and firing a cannon, with smoke coming out of it. To the right of the man, there are several other people holding rifles and other weapons, and a green and black umbrella is visible in the foreground. The sky is overcast and the overall atmosphere appears to be tense.
