En route, lookouts sighted mines drifting in the murky waters of the East China and Yellow Seas. Gunfire from the ships destroyed these menaces to navigation. The ships made port at Jinsen on 13 September and commenced offloading soon after arrival. The AKA's encountered difficulties posed by the 20- to 30-foot tidal range which permitted larger landing craft to discharge cargo only at specific times. After completing the unloading operations, the ships headed back to Okinawa, arriving there on 18 September.
