Number 105. On 12 October, the submarine cruised some southwest of the entrance to Tokyo Bay. Soon after she came to the surface, and her radar swept the surrounding seas, four pips showed themselves on the phosphorescent screen—two large and two small—which were identified as two battleships and two destroyers. Despite the fact that the phosphorescent waters would make his submarine stand out starkly in the night, Davenport closed at flank speed and fired a full spread of six torpedoes. The "fish" sped through the water toward their targets. He claimed success when explosions rumbled across the water, and flames lit up the night. Davenport turned the submarine to present her stern tubes to the enemy and loosed four more torpedoes. These all missed. Davenport's gallant and skillfully pressed attacks earned him his fourth Navy Cross. He felt that he had damaged a and had sunk a destroyer, but a study of Japanese records after the war did not verify either claim. [In fact the Trepang had damaged the Japanese destroyer Fuyutsuki off Omaesuki] Her supply of torpedoes exhausted, Trepang cleared the area and headed for the Marshall Islands. She reached Majuro on 23 October for voyage repairs alongside submarine tender and brief training. Second war patrol: November – December 1944 On 16 November, Trepang got underway for the Philippine Islands leading a "wolfpack" which also included sister ships and . The wolfpack's nickname was "ROY'S RANGERS" as Trepangs own commanding officer, Roy M Davenport, was the officer in charge of the pack. The weather was dark, windy, and rough on 6 December as Trepangs conning tower broke the surface after a day's submerged inshore patrol off Luzon. While shifting course toward deeper water, she detected a group of ships approaching from the northward. Upon closing to investigate, Trepang counted seven large ships and three escorts in the convoy which slowly approached the Philippines. Trepang radioed news of her "find" to her packmaster and then submerged. The submarine shot straight and true, sending freighter Banshu Maru Number 31 and cargo ship Jinyo Maru to the bottom in quick succession and damaging a third vessel, Fukuyo Maru. However, as Trepang came about to administer the coup de grace to Fukuyo Maru, the third cargo ship obligingly blew up and sank. Meanwhile, as Segundo and Razorback arrived on the scene, Trepang fired all of her remaining torpedoes at a fourth ship which,
