 and occasionally breaking off to investigate a contact report or to take special scouting dispositions by order of the pack commander. On 3 November, Jallao reported a five-ship force heading south, and the wolf pack moved to intercept. The contacts were moving at 20 kn (39.2 km/h), and Atule was never able to come within range for attack. However Pintado had better luck. That submarine's target was thought to be a large escorted oiler (actually the aircraft carrier Jun'yō), but before her torpedoes could strike the oiler crossed their path and disintegrated in a tremendous explosion which was seen and heard on board Atule. The smoke screen provided by the ensuing fires protected the target, and Pintado was forced to withdraw.

During the next ten days, the wolf pack occasionally sighted ships or aircraft, but was unable to attack. On 13 November, Jallao reported an enemy ship. Pintado and Atule altered course to intercept the contact, and at 0850, Atule sighted what appeared to be the foretop of a battleship

. Atule maneuvered to approach the force as closely as possible, hoping that the enemy ships would initiate a "zig-zag" course which would bring them within range of her torpedoes. The Japanese force indeed did begin to "zig-zag", but, instead of making them vulnerable, the maneuver took the force out of range. At 1115, contact was lost.

Later that day and throughout the next, the submarine played a game of hide and seek with Japanese planes equipped with radar

During this hunt, the Japanese covered all of the wolf pack's radio frequencies and intruded in Japanese as well as English, asking the Americans to "come in, please" in their best imitations of American aviators.

There, until after midnight on 20 November, she made only aircraft contacts. The submarine then sighted a slow moving surface vessel and moved in to attack. The night was dark, and the sky, clear. The enemy, identified later as Minesweeper Number 88, was protected by a squall during the early phase of Atules approach, but was perfectly silhouetted against a clear horizon when the submarine fired four torpedoes. The third torpedo hit at the forward stack with a terrific explosion.

. The submarine surfaced at dark and set course to intercept the transport shortly after midnight. As she set her sights on the target, one of the escorts also moved into view.
Atule fired six bow tubes and two stern tubes at the overlapping targets, scoring two hits on each. The escort, later identified as Patrol Boat Number 88, was claimed destroyed but survived the attack; and the transport, a 7,266-ton cargo ship named Santos Maru, went dead in the water. Atule moved out of range of the other two escorts which were wildly searching the area. The transport disappeared from view and from radar

 and the submarine returned to patrol.

On 27 November, a radar contact and subsequent visual sighting of a ship at anchor between Dequey Island and Ibuhos Island gave
Atule another chance for action. Approaching from the north of Dequey Island, Atule closed the transport to 2000 yd (1,828.8 m) and fired four torpedoes. The four hits spread the length of the ship; and, in the ensuing fire, the port side was seen to be blown almost completely away. The ship was racked by violent oil and ammunition explosions, and the flames were visible 15 miles away. One hour and eight minutes after the first hit, the ship blew apart. However, Atule was never officially credited with this sinking, because a postwar study of Japanese records did not substantiate the loss.

On 28 November, the submarine left her patrol station and headed for Majuro Atoll for refit alongside . Arriving on 11 December,
Atule ended a highly productive first patrol in which she accounted for almost 27,000 tons of enemy shipping destroyed.

The crew hastily abandoned the ship in time to see the stern break off and disappear. The forward section of the ship bobbed like a cork, so
Atule surfaced to finish off the freighter with gunfire. The freighter returned fire, and the submarine fired another torpedo which missed the target. Atule retired to await nightfall, when she again failed to sink the hulk with gunfire. She loosed another torpedo, which hit amidships, and the freighter began settling by the bow. Atule left the empty hulk in a vertical position with the midship section high in the air. After the war her victim was identified as Taiman Maru Number 1.
