[2] Convoy D was actually Part D (the equipment/baggage convoy) of Convoy No. 35 that departed Shanghai to transport the IJA’s 6th Infantry Division via Truk to Guadalcanal (after the decision is made to evacuate Guadalcanal, the convoy’s destination was changed to New Guinea). Part D departed Truk on 20 Jan '43 and arrived at Rabaul on 24 Jan '43 escorted by CH-18, CH-12 and CH-22 and CHOKO MARU No. 2 (and possibly destroyer HAMAKAZE part way).
