In the days that followed, "Thuban" continued to unload her vital cargo to supply the forces on shore, furnished ammunition for light cruiser , and took on casualties from Marine and Army units on the beach, occasionally approaching within less than a mile of the shore. Despite frequent air alerts, the attack cargo ship was soon remaining in the transport area unloading through the night. Toward midnight on the night of 22 June and 23 June, a shell from an enemy battery on Tinian passed low over the number three hatch and burst nearby on the port beam, but "Thuban" escaped damage. All hands remained at battle stations during the night as "Thuban" took on casualties, made smoke, and continued unloading.
