On arrival at Cid Harbour early on 10 June, Mills was informed that a Board of Inquiry, consisting of senior officers from HMA Ships and would be convened at 1100. 24 sailors were called before the Inquiry, and had to testify without formal representation. As the Inquiry was unable to identify any ringleaders, the problem was handed back to Mills to deal with as he saw fit. On 15 June, Mills summarily charged twelve men with joining a mutinous assembly (including one who had not participated), and two others with disobeying instructions to persuade the others to return to duty. Ten were sent to Stuart's Creek Gaol for periods between 21 and 60 days, then assigned to other ships, while the other four were punished less severely and remained aboard. This was despite the "Articles of War" prohibiting charges of mutiny being laid without a court martial, and no opportunity to defend themselves or request clemency was offered. The sailors claimed that the decision to disobey orders had come from a consensus of frustration, and later theorised that those punished had either witness the commander's actions during the air attack, or were the ones most likely to speak up for themselves against Mills.
