Both ships were transferred to Battleship Division 2 of the 2nd Fleet on 10 September. "Yamashiro" and "Fusō" alternated in the role of division flagship under Vice Admiral Shōji Nishimura. They departed Kure on 23 September for Lingga Island, carrying the Army's 25th Independent Mixed Regiment, and escaped an attack by the submarine the next day. They arrived on 4 October, then transferred to Brunei to offload their troops and refuel in preparation for Operation "Shō-Gō", the attempt to destroy the American fleet conducting the invasion of Leyte.
