LtCdr Arnold H. Holtz’s (USNA ’31) USS TUNA (SS-203) is patrolling off Kolumbangara Island, near New Georgia, British
Solomon Islands to intercept traffic between Faisi and Munda. At 1705, TUNA’s lookouts spot what appears to be an “8,000 ton
freighter escorted by a new escort of about 500 tons.” Between 1730~1733, Holtz fires four torpedoes. At 1732, TUNA’s crew
hears an explosion and Holtz sees through his periscope that he scored a hit forward of the freighter’s bridge. She soon
takes on a list to port.
Holtz’s last view is of the freighter [probably SHONAN MARU] dead in the water and lowering boats because at 1735, TUNA is
rocked by two bombs dropped by an aircraft overhead. Then at 1739, the escort drops a pattern of eight depth charges nearby. At 1800, the the escort drops another six DCs. TUNA goes deep and evades and escapes. [3]

17 November 1943:
At 0400, SHONAN MARU and HACHIJO arrive at Otaru. RONSAN MARU arrives later.
8 September 1944:
Off Hokkaido. At 1415, LtCdr John H. Turner’s (USNA 36) USS SEAL (SS-183) makes radar contact at 8 miles on convoy KI-505 enroute to the Kuriles consisting of SHONAN and NAMIKAZE MARUs and four unidentified ships escorted by destroyer KAMIKAZE and an unsknown patrol craft. At 1419, the masts of the convoy are seen coming out of the haze heading eastward. Turner begins an “end-around” to NW.
About 2014, SEAL heads towards the convoy on the surface making 15 knots. At 2049, Turner fires four torpedoes at overlapping targets xt 47-28N, 148-20E. At 2052, NAMIKAZE MARU's stern is blown off. 40 men are KIA. Later, she is towed to Otaru by KAMIKAZE and declared a constructive total loss (CTL).
At 2055, Turner sees two ships burning. At 2347, he again attacks the convoy, now comprised of only four ships. SEAL fires four torpedoes and gets two hits on a freighter. In all, Turner claims damage to two other ships during the engagement.
9 September 1944:
Sea of Okhotsk, N of Etorofu, Kuriles. At 0250, SEAL fires four stern torpedoes that hit and sink SHONAN MARU at 47-03N, 148-18E. Casualties are unknown.
Authors' Notes:
[1] Not to be confused with ore carrier SHONAN MARU (42/5104 grt).
[2] At least 120 men died in prison camps within the next three weeks of dysentery contracted aboard SINGAPORE (SHONAN) MARU.
[3] Alden's "United States and Allied Submarine Successes in the Pacific and Far East During World War II, 4th ed., notes the ship was probably damaged, but her identity is questionable.
However, the long period between this attack and the next known movement of SHONAN MARU seems to indicate that she may well have been Holtz's target.
