Upon dissolution of the ovJar.Ministry and the Japanese General Staff, and the transfer of their former functions to the Demobilization Bureau, research and compilation continued and developed into a series of historical monogrsphs. The paucity of original orders, plans and unit journals, which are normally essential in the preparations of this type of record, most of which were lost or destroyed daring field opera- tions or bombing raids rendered the task of compilation most difficult; particularly distressinr has been the complete lack of official strength reports, norn al in AG or G3 records. However, while many of the important orders, plans and estimates have been reconstructed from memory and. the refore are not textually identi- cal with the originals, they are believed to be generally accurate and reliable. Under the supervision of the Demobilization Bureau, the basic material contained in this monograph was compiled and written in Japanese by former officers,_ on duty in cormland and staff units within major units during the period of operations-. Translation was effected through the facilities of Allied Translators and Interpreters Service, G2, General Headquarters,: Far East Command. This Japanese Operational Monograph was rewritten in English by the Japanese Research Division, Military History Section, General Headquarters, Far East Command and is based on the transla- tion of the Japanese original4, Editorial corrections were limited to those necessary for coherence and accuracy.
