A radio message was intercepted by the USS Baltimore. It was from the Commander, Hawaiian Sea Frontier and read as follows: "Possible enemy task force located 200 miles north of Oahu, HI. Alert all activities. 231133". As nothing further was heard about it, it was later assumed to be an erroneous report. It was a rather startling reminder, however, that a powerful enemy fleet is still at large in the Pacific and may appear at any point on further surprise missions. Upon arrival at Oahu, HI it was found one of our air pilots had made the report and that he still believed it to have been correct. It was probably an optical illusion as careful search by other pilots failed to disclose any enemy vessals.
