About the monument to the 8th Pennsylvania Cavalry
Why is there a tree trunk underneath the horse? Because it holds up the weight of the stone horse and rider.
The 8th Pennsylvania Cavalry is the only equestrian monument on the battlefield with a horse that is both freestanding and made of stone. Other monuments with stone horses are carved as a bas-relief into a supporting wall. The legs of metal statues can bear the entire weight – the four and a half ton statue of General Reynolds is perfectly balanced on only two legs.
But the freestanding stone horse and rider of the 8th Pennsylvania Cavalry needed a little help to stay up, so the sculptor added a supportive tree stump
