Hancock's statue is in a somewhat twisted pose with his horse staring in one direction and him in the other. The horse has the front left foot raised into the air.
The horse code states that a horse with one foot raised indicates that the rider was wounded, but survived. Hancock was indeed wounded in battle, several times. He was wounded at Churubusco in the knee, in the abdomen during The Battle of Fredricksburg, and again in Battle of Chancellorsville. Was he wounded at Gettysburg? Yes, he was during Pickett's Charge.
Hancock was never killed during battle, but he did die while in service. He didn't die of a wound. Hancock had diabetes and died of an infected carbuncle. Having been wounded, but not killed during battle, Hancock's history is represented correctly by the horse's legs.
