A Memorial Stone is in place with his Mother and Father's grave, at Vivian Cemetery, Caddo Parish, Vivian, Louisiana.

He was lost aboard the submarine USS Swordfish SS-193 in WWII. He was a Radioman, Third Class in the U S Navy. He received the Purple Heart for his service to his country. He is, also, recognized at the Tablets of the Missing at Honolulu Memorial, Honolulu, Hawaii.

Marshall Edward Cox, Jr is the son of Marshall Edward Cox Sr. and May Agnes Beaudreaux Cox. He is my uncle whom I never met as he was lost prior to my birth.

Thanks to those who have helped keep alive the importance of the service of these courageous men.

The USS Swordfish (SS-193) was a Sargo-class World War II era submarine.

The namesake of the USS Swordfish is a large fish with a long, sword-like beak and a high dorsal fin.

The radio call sign of the USS Swordfish was NAN-UNCLE-DOG-GEORGE.

On December 22, 1944, the Swordfish, captained by Commander Keats E. Montross, departed Pearl Harbor for her thirteenth and final war patrol. She had received orders to patrol in an area off the Ryukyu Islands. She had also been outfitted with special equipment for a photo reconnaissance mission at Okinawa. After stopping at Midway Island to top off her fuel, she headed west for the big Japanese stronghold in the Nansei Shoto chain. On January 3, 1945, she acknowledged receipt of new orders to proceed to and to patrol near the approximate geographic position 30° 00' N, 132° 00' E until further notice. The reason for this move was to keep her out of harms way during a planned January carrier strike on the Ryukyus. Her acknowledgement of this order was the last communication ever received from the Swordfish. On January 9, 1945, she was ordered to proceed to the Nansei Shoto Archipelago to perform her special mission. Upon completion of the photographic and observation mission, she was told to proceed to the submarine base at Saipan, unless she was unable to communicate by radio, in which case she was supposed to return to Midway. When the Swordfish failed to appear at Saipan or Midway, and silence was the only response to radio messages sent to her, it became obvious she was lost. 1

On February 15, 1945, she was reported as presumed lost due to unknown causes. The public announcement was made on May 4, 1945.

Navy Department Communiqué No. 595, May 4, 1945

1. The submarine USS Swordfish is overdue from patrol and presumed lost. Next of kin of officers and crew have been informed.

Loss Possibilities

1. The Swordfish was probably sunk by depth charges, on January 5, 1945, at the approximate geographic position 29° 25' N, 141° 07' E, which is southeast of Tori-shima island, an uninhabited volcanic island at the south end of the Izu Islands. On that date, near that location, at about 1705 hours, the 572-ton Japanese Army cargo vessel Shoto Maru was hit in the bow by a torpedo and sank at about 1906 hours. John D. Alden attributes this attack and the sinking to the Swordfish. The Japanese coastal defense vessel CD-4 conducted a counterattack with depth charges and reported that oil continued to rise to the surface for the next thirty hours. 2

2. The Swordfish possibly sank sometime after January 9, 1945, as a result of hitting a mine. During the first half of 1944, the Japanese had laid four minefields in the Okinawa area. On January 9, 1945, the Swordfish had been ordered to proceed to this area to complete a photographic reconnaissance assignment. This mission may have taken her into one of the minefields laid in 1944 or into freshly laid inshore minefields planted to defend Okinawan beach approaches. 3

3. On January 12, 1945, the USS Kete (SS-369), while on station in the Okinawa area, reported a possible contact with a nearby submersible. The Kete was unable to positively identify the contact, but the Swordfish was expected to be in the vicinity at that time. About four hours later, the Kete heard the sound of a heavy barrage of depth charges. Japanese records reviewed after the war did not record the event heard by the Kete. But such a heavy barrage could have been aimed at the Swordfish. 4

The bottom line is no one knows for certain what happened to the Swordfish. This long serving submarine and her valiant crew went down together leaving a significant record of accomplishments in their wake.

A list of the men lost with the Swordfish is maintained at On Eternal Patrol.

The Swordfish was scored by JANAC with sinking 47,928 tons of enemy shipping in twelve vessels. Her Alden-McDonald score is sixteen vessels sunk for 55,641 tons and four vessels damaged for 26,150 tons. Her SORG score is seventeen vessels sunk for 101,400 tons and nine vessels damaged for 61,900 tons. The Swordfish earned eight battle stars for her World War II service in her distinguished thirteen-patrol career. She sank the Atsutasan Maru, the first Japanese ship sunk by a U. S. submarine in the Pacific war. 5

Swordfish (SS-193)

Compiled by Paul W. Wittmer and Charles R. Hinman, originally from:

U.S. Submarine Losses World War II, NAVPERS 15,784, 1949 ISSUE

SWORDFISH, under Cdr. K. E. Montross, left Pearl Harbor on 22 December 1944, to carry on her thirteenth patrol in the vicinity of Nansei Shoto. She topped off with fuel at Midway on 26 December and left that day for her area. In addition to her regular patrol, SWORDFISH was to conduct photographic reconnaissance of Okinawa, for preparation of the Okinawa Campaign.

On 2 January, SWORDFISH was ordered to delay carrying out her assigned tasks in order to keep her clear of the Nansei Shoto area until completion of carrier based air strikes, which were scheduled. She was directed to patrol the general vicinity of 30° 00'N, 132° 00'E until further orders were received. In the last communication received from SWORDFISH, she acknowledged receipt of these orders on 3 January.

On 9 January 1945, SWORDFISH was directed to proceed to the vicinity of Okinawa to carry out her special mission. It was estimated that the task would not take more than seven days after arrival on station, which she should have reached on 11 January. Upon completion of her mission, SWORDFISH was to proceed to Saipan, or to Midway if she was unable to transmit by radio. Since neither place had seen her by 15 February, and repeated attempts to raise her by radio had failed, she was reported as presumed lost on that date.

In the report of her loss, mention was made that KETE, which at the time was patrolling the vicinity of Okinawa, reported that on the morning of 12 January she contacted a submarine by radar. It was believed that contact was with SWORDFISH since it was in 27° 00'N, 128° 40'E. Four hours later KETE heard heavy depth charging from this area and it was believed that this attack might have been the cause of SWORDFISH's loss.

Japanese information on anti-submarine attacks does not mention the attack heard by KETE on 12 January, and records no attacks in which SWORDFISH is likely to have been the victim. However, it is now known that there were many mines planted around Okinawa, since the Japanese were expecting an Allied invasion of that Island. The majority of the mines were planted close in. It is considered about equally likely that SWORDFISH was sunk by depth charge attack before she reached Okinawa for her special mission or that she was lost to a mine at that place.

SWORDFISH, in the twelve patrols before her fatal thirteenth, sank twenty-one ships, amounting to 113,100 tons, and damaged an additional eight, totaling 45,800 tons. Her first patrol began the day after the attack on Pearl Harbor, and was conducted west of the Philippines. SWORDFISH sank four freighters, varying from 3,900 tons to 9,400 tons, and damaged a fifth. At the time, this was the most successful patrol in the war. She conducted her second patrol in the lesser Philippine group and among the small Islands between Celebes and New Guinea. Here she sank three medium freighters and a tanker. She also evacuated President Quezon, his family, Vice President Osmena, Chief Justice Santos, and three officers in the Philippine Army from Corregidor and took them to Panay, where they boarded a motor tender. SWORDFISH returned to Manila Bay and evacuated eleven more Philippine officials. SWORDFISH's primary mission on her third patrol was to deliver 40 tons of supplies to the beleaguered Corregidor. However, on 10 April 1942 ComSubsAP told SWORDFISH to neglect her special mission and patrol offensively. SWORDFISH made no attacks on this patrol, but did perform reconnaissance of several islands.

The South China Sea area was the scene of this ship's fourth patrol, and she sank a freighter and a tanker, while she damaged two freighters. She returned to the South China Sea for her fifth patrol, but did no damage to the enemy. SWORDFISH went to the area west of Bougainville for her sixth patrol, and sank a medium freighter and damaged a second freighter. She went again to the Solomons for her seventh patrol and sank a freighter. On her eighth patrol, SWORDFISH covered the Palau-Truk-Rabaul areas during August and September 1943. Here she sank a freighter and a transport, while damaging a freighter-transport. Her ninth patrol was made south of Japan, but she made no attacks, and the patrol was cut short by material defects in SWORDFISH. On her tenth patrol, in the same area as her ninth, SWORDFISH sank a freighter-transport, and two medium freighters.

USS Swordfish Crew

This ship covered the Marianas on her eleventh patrol; she damaged two freighters. On her twelfth patrol, conducted in the Bonins, SWORDFISH sank a freighter and two small trawlers, while she damaged a third trawler. In addition, during this patrol, on 9 June 1944, SWORDFISH sank the Japanese destroyer MATSUKAZE in a night submerged attack as the enemy ship was hearing down for an attack. SWORDFISH was awarded the Navy Unit Commendation for the period of her first, second and fourth patrols.
