The next day, nausea again gripped everyone on board "Angler". The situation was reported to Fremantle, and the submarine was ordered to return at once. Things onboard "Angler" continued to grow worse. On 22 May, Lieutenant Commander Olsen noted in the log: "Physical condition of officers and crew is so bad that it is difficult to maintain watch, either surface or submerged. Put crew on fruit juice alone, no water. Held thorough field day in case boat is contaminated. Exercised special supervision in cooking, dishwashing." On 23 May he wrote, "Decided to run submerged as we did not have enough able-bodied people to maintain proper surface watch."
