WHO WAS BLACK JACK?
Most of you at least will have seen a photo of JFKs funeral procession. In those photos, you always see that marvelous riderless black horse who carried a saddle with boots turned backwards in the stirrups. This magnificent horse was Black Jack.

WHAT IS A CAPARISONED HORSE?
The Caparisoned horse is the riderless horse who follows the caissons (6 horses pulling the cart which carries the casket of the fallen soldier). The caparisoned horse represents the soldier who will no longer ride in the brigade. The caparisoned horse wears the cavalry saddle, the sword and backwards boots in the stirrups, symbolizing the end of his tenure. If you watch any footage of military funerals, you will see this horse.

On Monday, they headed back to the Capitol Building to escort Kennedys casket again. Black Jack was wild during the procession to the White House, and Arthur was afraid he was going to lose hold of him. At one point, Black Jack stomped down on Arthurs toe so hard he was sure it was broken, but he couldnt even bend down to rub it, or show any emotion at all due to the television cameras and witnesses.
Despite his antics, the media carried his image all over the world, and the beauty of his role in Kennedys funeral, as well as his display of spirit, touched the American people. Jacqueline Kennedy herself was one of many who became admirers of Black Jack.
On Nov. 27, Jacqueline informed the Secretary of the Army that she wanted to buy Black Jack when he was retired. Her request was acknowledged, and she later received Black Jacks caparison, which included his saddle, bridle, saddle blanket, sword, boots and spurs.
