  • The Japanese intercepted, but could not decode, a report by USS Cuttlefish returning from patrol near Saipan, Mariana Islands. Around midnight, the Japanese Navy 6th (Submarine) Fleet at Kwajalein, Marshall Islands also reported monitoring messages exchanged by two American task groups located 170 miles north-northeast of Midway Atoll, moving westwards. Aboard battleship Yamato, Admiral Yamamoto suggested that the information be relayed to the First Air Fleet flagship carrier Akagi, but senior staff officer Captain Kuroshima cautioned not to break radio silence. Elsewhere, the transport fleet of the Japanese Aleutian invasion fleet set sail from the main island of Honshu of the Japanese home islands; it was consisted of 8 transports. In the northern Pacific Ocean, Japanese submarine I-25 surfaced for the launching of her floatplane for a reconnaissance missiong over Dutch Harbor in the Aleutian Islands; an American cruiser sailed near by luck but failed to spot the submarine; I-25 would continue with the reconnaissance mission after a short while. ww2dbase [Battle of Midway and the Aleutian Islands | CPC]
