USS Sargo (SS-188) - War Patrols Under Tyrell D. Jacobs

War Patrols Under Tyrell D. Jacobs

The next day (under the command of torpedo specialist Tyrell D. Jacobs, Class of 1927), the submarine got underway for her first war patrol, which took her along the coast of French Indochina and to the Netherlands East Indies. Off the major Japanese base at Cam Ranh Bay, directed her to three cruisers on 14 December, which Sargo was unable to gain position to attack when they appeared as scheduled. Expecting a convoy, she went in closer, and that night detected a freighter, firing one torpedo; it prematured eighteen seconds later. Confidence in the Mark VI shaken, she switched to contact pistol afterward.

On 24 December, she found two freighters, firing two torpedoes at one, one at the other, from about 1,000 yards (900 m), scoring no hits. Temporarily losing depth control, she broached, and the target turned away; Sargo fired two stern tubes at 1,800 yards (1,600 m), with no more success. The next day, she sighted a pair of merchantmen, but was unable to gain firing position. Some time afterward, she came on two more merchantmen and fired two stern torpedoes at the rearmost of them, from closer yet, 900 yards (800 m); both again missed. By now frustrated, after eight torpedoes with zero results, when two additional merchantmen came in view an hour later, Sargo took extra pains to get it right, pursuing for fifty-seven minutes and making certain TDC bearings matched perfectly before firing two torpedoes at each ship, at an average of 1000 yards; all missed.

After her skipper discovered the torpedoes were running too deep, and correcting the problem, Sargo detected a target at dusk on 26 December losing, then regaining, contact, and running ahead, so be able to get good position. Then weather intervened, and the ships escaped.

A few days afterward, a big, slow tanker gave Sargo another opportunity, and again, the approach was meticulous, firing one torpedo at a close 1,200 yards (1,100 m). It missed. In exasperation, Sargo signaled headquarters, questioning the Mark 14's reliability on an open radio circuit.

On 20 January 1942, she assisted in the rescue of the crew of S-36 after she ran aground on Taku Reef in the Makassar Strait. Sargo remained surfaced, relaying distress messages to friendly aircraft and surface ships. After the rescue by the Dutch merchant ship Siberote, Sargo headed for Java, and arrived at Soerabaja on 25 January.

Here, she offloaded all her reload torpedoes (keeping only those in her tubes) and three-inch ammunition, and took on one million rounds of .30-caliber ammunition desperately needed by Allied forces in the Philippines. She sortied 5 February, avoiding the usual traffic lanes, and arrived in Polloc Harbor nine days later. After delivering her vital cargo to Mindanao, she returned to Soerabaja with 24 Boeing B-17 specialists from Clark Field on board.

Sailing from Soerabaja on 25 February, she headed for Australia and was one day out of Fremantle when she was attacked by an Australian plane which mistook her for a Japanese submarine. Although a near miss by a bomb caused minor damage, Sargo arrived safely at Fremantle on 5 March with 31 passengers from Java.
