On 1 August, BatDiv 8 was detached to form Support Unit 38.1.2; the ships continued their attacks on coastal cities in company with TF 37. One of "Indiana"s Kingfishers accidentally crashed in the sea on 7 August, killing its crew. The ships of BatDiv 8 conducted a second attack on Kamaishi on 9 August, with "Indiana" firing a total of 270 shells between 12:46 and 14:45. Poor visibility again hampered the observers, though this proved to be the ship's last offensive operation. Japan agreed to surrender unconditionally on 15 August while "Indiana" was en route to the coast to support another wave of carrier strikes. Instead of munitions, food and medical supplies were loaded onto the carriers' aircraft to be dropped on prisoner of war (POW) camps. "Indiana" contributed a landing party to be sent ashore on 30 August, which was part of the initial occupation forces.
