Sadly almost certainly a fake photo. Issues with how you’d get such a sharp image of anyone in motion in 1912 aside, look at the shadows and see where the light is coming from:
Our boys with the hats are lit from the right
The slats on the building are lit from top right
Now look at battering ram’s helmet, especially where it meets the wall. Where’s the shadow? Where would you expect the shadow to be?
