However, in September 1943 the 27th's objective changed. The difficulty of providing adequate naval and air support of simultaneous operations at Tarawa and the much more distant Nauru, plus lack of sufficient transport to carry the entire division required to take the larger, more heavily defended Nauru, caused Admiral Nimitz to shift the 27th's objective from Nauru to Makin Atoll, in the northeast Gilberts. The 27th Infantry Division staff learned the change of target on 28 September, scrapped the original Nauru plan, and began planning to capture Makin.
