For the commanders of the Japanese mother submarines, waiting anxiously at the rendezvous point, off Port Hacking, south of the Heads, there was little information to go on. They had to remain out of sight to avoid allied air and sea searches.

On 3 June, after three days had passed with no news of the midget submarines, Captain Sasaki gave up hope of the midgets returning and instructed the submarines to switch their attention to finding and sinking enemy shipping in the vicinity. Within a few days they had sunk two freighters, the Iron Chieftain and the Iron Crown.
