For extraordinary heroism in the line of his profession as a senior engineer officer on board the U.S.S. Memphis, at a time when the vessel was suffering total destruction from a hurricane while anchored off Santo Domingo City, 29 August 1916. Lt. Jones did everything possible to get the engines and boilers ready, and if the elements that burst upon the vessel had delayed for a few minutes, the engines would have saved the vessel. With boilers and steampipes bursting about him in clouds of scalding steam, with thousands of tons of water coming down upon him and in almost complete darkness, Lt. Jones nobly remained at his post as long as the engines would turn over, exhibiting the most supreme unselfish heroism which inspired the officers and men who were with him. When the boilers exploded, Lt. Jones, accompanied by 2 of his shipmates, rushed into the firerooms and drove the men there out, dragging some, carrying others to the engineroom, where there was air to be breathed instead of steam. Lt. Jones' action on this occasion was above and beyond the call of duty.
