Rear Admiral (Vice Admiral, posthumously) Goto Aritomo's (38)(former CO of MUTSU) CruDiv 6's AOBA, KINUGASA, KAKO, FURUTAKA, seaplane tender CHIYODA and two other destroyers also reinforce Kajioka. Rear Admiral Abe, now senior officer present, has overall command.

SubDiv 26's RO-60, RO-61 and RO-62 are assigned to the reinforced Wake Occupation Group and sortie from Kwajalein.

21 December 1941:
25 miles SW of Wake. About 1600 (local), RO-60 is spotted on the surface by a USMC Wildcat fighter piloted by 2Lt David D. Kliewer of VMF-211. Kliewer strafes the sub and drops two 100-lb bombs that damage RO-60's periscopes and puncture several diving tanks. RO-60 crash-dives to escape the attack. That night, following an inspection of her hull, LtCdr Fujimori decides RO-60 can no longer safely dive. [1]

23 December 1941: The Second Attack on Wake Island:
After a magnificent stand, Wake's garrison is overwhelmed and its few defenders surrender. Thereafter, RO-60 and RO-62 are ordered to depart their patrol area for Kwajalein.

29 December 1941:
RO-60 returns to Kwajalein. About 0200, she loses her position in bad weather and runs hard aground on a reef N of the atoll at 09-00N, 167-30E, splitting her starboard diving tanks and damaging her pressure hull.

About 1300, ComSubRon 7, Rear Admiral Onishi arrives with his flagship, submarine tender JINGEI, to personally supervise the rescue operation. In heavy surf, RO-60 receives new damage, her list increases and she has to be abandoned. Secret documents are destroyed and all of her 66 crewmen are taken aboard the JINGEI.[2]

LtCdr Fujimori returns to Japan and is reassigned as the CO of the old minelayer submarine I-121.

15 January 1942:
Removed from the Navy List.


Authors' Notes:
[1] Sources vary as to the date of Kliewer's attack on RO-60. Some sources say 12 Dec '41, but Japanese sources place it at 21 Dec '41. The later date makes sense since it is improbable that she could stay surfaced off Wake for 11 days!

[2] RO-60's hulk is strafed at some unknown time during the war. Its torpedoes explode and blow the submarine apart. Later, divers find RO-60's forward section laying 200 yards ahead of the stern. The conning tower lays 150 yards from the forward section and the deck gun 560 yards beyond. The aft section lays against the reef. Wood deck planking is partially intact and wreckage is strewn all over the reef.
