could not close the range. She then returned to Attu and, on 20 June, sighted an enemy destroyer patrolling off Sarana Bay. Between 07:00 and 10:00, she sighted and lost the target twice as it moved in and out of the fog. At 11:55, she sighted a large tanker inside the bay. Fifty minutes later, she slipped past a destroyer guarding the entrance and began maneuvering into the bay. Her target was engaged in refueling another destroyer. At 13:50, S-34 grounded at a depth of 48 feet. Run up to 25 feet, she came out of the water to the waterline; then backed off into deep water. Within five minutes, she was operating at periscope depth. The fueling destroyer had gotten underway from alongside the tanker and was racing across the intervening waters. S-34 fired two torpedoes at the destroyer, forcing the enemy to swerve and pass down the submarine's port side. Unable then to bring her tubes to bear on the tanker, the S-boat swung right to avoid depth charges. At 14:03, she bottomed in 164 feet, just inside the entrance to the bay, where she remained until 23:30. During that time, only one destroyer was heard searching for her, the other, which had conducted the high speed attack, was heard pinging from the same spot for nine hours. She had presumably grounded after the attack, but, by 23:00, the tide had risen and she had moved to join in the search for the submarine. At 23:30, S-34 began to make her way out of the bay. Twenty minutes later, one of the destroyers located her. The pace of the hunt was stepped up, but the quarry evaded attempts to destroy her. By 02:30 on 21 June, she had maneuvered out of the bay, lost her pursuer; and set a course for Dutch Harbor. On 26 June, S-34 moored in Dutch Harbor, whence she proceeded to Bremerton, Washington, for overhaul and training duty. Third war patrol On 13 September, she returned to Unalaska, and, on 14 September, she departed from Dutch Harbor on her third war patrol. Two days later, she crossed the 180th meridian; and, on 17 September, she arrived in the Semichi area and commenced crossing the Japanese supply lanes to the western Aleutians in search of targets. On 20 September, while off Buldir, her after radio mast was partially carried away by heavy seas and threatened
