12/6/41 1900 Hours – South west of Pearl

On board the I-22 and the I-27 the signal officers decoded messages from the fleet headquarters. Each submarine had a prearranged time to surface, listen for traffic and send if the need arose. The other ten submarines which had been guarding the entrance to Pearl had already moved off to follow a large fleet of surface ships. The I-22 would now move east near to the mouth of the harbor, the I-27 was to move just south of the I-22 and cover it if an action was initiated. The two captains were informed that five midget submarines had already been launched and should be entering the harbor. Both captains informed their crews and they moved to the assigned areas. They would remain vigilant but would not initiate any action until the appointed time. Before leaving on this mission most of the officers and men of the I-22 had cut a lock of hair and left it for their relatives. Many of them did not expect to return.
