oil fields. The operation was completed, and Yura returned to its base at Camranh Bay, Indochina by the end of the year. Subron 5 was also part of the advance screening force for the Battle of Midway. Daigo became vice admiral on 1 November 1943. He was assigned command of the Eastern Attack Group which carried out midget submarine and merchant shipping attacks on the east coast of Australia. Daigo was Commandant of the Naval Submarine School from 23 August 1944 and final Commander in Chief of the IJN 6th Fleet from 1 May 1945. During these assignments, he was involved in the kaiten human-torpedo program. After the end of the war, Daigo was arrested by SCAP authorities at the request of the Netherlands government, and was extradited to Batavia in the Dutch East Indies, where he was charged with war crimes in connection with the kidnapping, torture and massacre of 21,000 people (including women and children) by Japanese troops in Pontianak during the Pontianak incidents. After being held for several months under severe conditions, he was found guilty in a closed military tribunal at Pontianak after only three hours of testimony, during which time he was not allowed to speak in his own defense. He was found guilty and executed with a rifle shot to the stomach on 6 December 1947. As Daigo was commander of submarine forces, (although from 8 November 1943 the 22nd Special Guard Division based at Balikpapan, Borneo fell nominally under his command), his connection (if any) with the events in Pontianak from 23 April 1943 – 28 June 1944 remain very unclear. Whereas other "Class B" war criminals found guilty of professional negligence for atrocities committed by junior staff under their nominal command were sentenced to several years in prison, the speed and secrecy surrounding his trial, and the severity and brutality of his punishment, have created questions which remain unanswered.
