canoes as the Japanese were paying well for information. Weather, however, proved to be the worst impediment, encountered as frequent rains and heavy seas hindered her hunting. On the night of 19 July, S-42 returned to Adler Bay; reembarked the Australian intelligence officer, then got underway for Brisbane, where she arrived on 28 July. During the first week in August, the Allied offensive began with the landings on Guadalcanal. Two weeks later, on 21 August, S-42 (now commanded by Harley K. Nauman, Class of 1934) headed for the Solomons to support the offensive by patrolling in the already bloodied and iron-filled waters of the Savo Island–Cape Esperance area. On 23 August, an engine room hatch, improperly latched, began to leak — 15 gallons per hour at 90 feet. Wooden wedges were driven into the coaming, reducing the flow to a drip. S-42 continued on to the Solomons. She arrived on station five days later and remained into September; but — without modern electronics, quick maneuverability, and speed — she was unable to close the night convoys from Rabaul. Upkeep at Brisbane occupied the period between 19 September and 19 October. On 20 October, she headed for the Solomons to intercept traffic on the Rabaul-Faisi-Buin line, as well as lay mines. Assigned to Bougainville Strait, she again made many contacts, but was unable to score. On 2 November, she fired four torpedoes at a destroyer steaming in company with three others. An explosion was heard, but depth charge attacks precluded determining the results. On 5 November, she departed the area and made for the Fiji Islands. On 16 November, she moored in Suva harbor, where she was joined by others of her division and, on 1 December, she got underway to return to the United States. Transiting the Panama Canal in early January 1943, she proceeded to Cuba in February; provided antisubmarine warfare training services for newly commissioned destroyers through March, then continued on to Philadelphia, where she underwent overhaul and acquired air conditioning and radar. In late June, she departed Hampton Roads for San Diego, whence she sailed for the Aleutian Islands in mid-August. On 2 September, she departed Dutch Harbor for the Kuril Islands and her only North Pacific war patrol. Stopping en route at Attu, the forty-day patrol was spent primarily in the Paramushiro-Onekotan area, and contributed no sinkings or damage. She returned to Dutch Harbor on 12
