Swordfish (SS-193)

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. [Editor's note: Actual entry in patrol report is as follows:  "0508  Friendly radar interference - 282° T."] 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. [Actual entry in KETE patrol report is as follows:  "0949  Heard about 15 distant depth charges - Patrol craft were still around."]

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. [Editor's note: On January 4 or 5 (accounts differ), a Japanese freighter was torpedoed and sunk by a submarine southeast of Tori Shima, at the south end of the Izu Islands, at 29-25N, 141-07E.  An escort vessel counterattacked with depth charges, after which oil reportedly rose to the surface for the next thirty hours.  Swordfish could have been near Tori Shima on her way to her temporary patrol area in the Osumi Islands.  However, there is no conclusive evidence that she was involved in this battle.]
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 ComSubsAF 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.

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.
