Arrives at Kimbe Bay, unloads her cargo, departs on the same day.

4 April 1944:
Arrives at Rabaul, departs for Truk on that same day. I-2 is scheduled to arrive by 11 April.

7 April 1944:
Bismarck Sea, 50 miles WNW of New Hanover. At 0630, LtCdr D.E. Cochrane's USS SAUFLEY (DD-465), on patrol in the Emirau-Massau area, gains sonar contact on a submerged submarine. At 0645 she drops a pattern of 9 depth charges, followed by 9 more half hour later. Her soundman reports two underwater explosions. By 0723, oil covers the area. I-2 sinks at 02-17S, 149-14E. LtCdr Yamaguchi and all 110 hands are KIA. [8]

4 May 1944:
I-2 is presumed lost off New Ireland.

10 June 1944:
Removed from the Navy List.

Authors Note:
[1] Rohwer and others have credited I-2 with the sinking of the Dutch steamer PARIGI. In reality, that vessel was intercepted and sunk by the IJN destroyers ARASHI and NOWAKI.

[2] I-2's target was probably the Dutch merchant GENERAAL VERSPIJCK.

[3] The "cruiser" sighted by I-2 may have been USS McCALLA (DD-488) rescuing survivors after the battle. Several sources credit I-2 attacking McCALLA that day, but this is not substantiated by Japanese records.

[4] Lt Richard H. O'Kane (later Rear Admiral, MOH), then a member of tracking party, identified the same submarine as I-15. A recent theory suggests that WAHOO's target could have been I-22, even though the latter had been lost earlier.

[5] USS WAHOO was credited with sinking 1,955-ton submarine I-2, but postwar that victory was discredited by the JANAC (Joint Army-Navy Assessment Committee).

[6] A 1993 British history of ULTRA operations assures that I-2 was damaged heavily enough to return to Shortland surfaced. This mistake seems to go back to a mistranslation that confuses the identities of the attackers and their target.

[7] Samuel E. Morison's "History of United States Naval Operations in World War II. Aleutians, Gilberts and Marshalls" suggests that I-2 and I-157 were, in fact, grounded off Kiska at that time and "returned without accomplishing their missions." This is not confirmed by SubDiv 7's War Diary. A detailed clarification about that incident can be found in postwar memoirs of I-2's erstwhile CO.

[8] USS SAUFLEY sank another IJN submarine (RO-101) in September 1943.
