During the bombardment on 15 September, "Tennessee" was detached to nearby Peleliu to contribute her fire to the landing there. The next day, she returned to Anguar and resumed the bombardment there. Intent on demolishing the lighthouse, "Tennessee" steamed into position, but while she was training her guns on the target, the light cruiser fired a barrage of shells that destroyed the lighthouse. On 17 September, the Army's 81st Infantry Division stormed the beaches, and "Tennessee" remained offshore to provide fire support for the following two days. The American infantry encountered little serious resistance, and the Japanese garrison had been destroyed by 20 September, allowing "Tennessee" to steam to Kossol Roads, where she replenished fuel and ammunition. On 28 September, she departed for Manus in the Admiralty Islands to begin preparations for the Philippines operations. There, Rear Admiral Theodore E. Chandler replaced Kingman as the commander of Battleship Division Two.
