The Third Cannonball Exploded on the Princeton

After lunch, the band resumed playing and an impromptu sing-along began. It was suggested that a third cannonball should be fired in honor of George Washington as the ship sailed past his old home at Mount Vernon. Most of the cabinet, several senators and congressmen gathered topside on the Princeton's bow to watch the third firing. They waited for President Tyler to join them, but when word was sent that he'd been detained below deck, it was decided to proceed without him. In total, six men were killed in the explosion.
