4TH Marine Division Operation Plan Number 49-44

Abstract

IWO JIMA is reported to be defended by a force of approximately 12,000-14,000. This includes Inf, Arty, Engrs, and airbase Pers. It is believed that the enemy plans to defend the island with at least six Inf Bns disposed as a perimeter defense, with possibly three Inf Bns centrally located to be used as a strong mobile Res. These Trs may be expected to defend w0o JIMA with the same fanatical spirit which has been displayed in every area where the enemy has been encountered. (b) Due to the proximity of the JAPANESE EMPIRE, air Atks can be expected at any time. An attempted naval intervention with surface or sub-surface vessels is also possible.
