PART CHAPTER 1.1 1, I11 MANAGERIAL POPULATION ACCOUNT RECORD COMMENTS Basic planning for camp operation underwent several revisions due to increases in population estimates which gradually developed for all Task Force Groups. The initial planning contemplated having two temporary camps, one each at Bikini and Eniwetok Atolls. The development of Bikini Atoll for Operation CASTLE is described in limited detail in Chapter 2, which follows. Suffice it to say, the original concept in the Fall of 1952 of a 500- man "shot island" camp had, by the end of 1953, evolved into an operational task involving temporary camp facilities on four different islands of the atoll with a total capacity of approximately 1900 people. At Eniwetok Atoll, a camp site previously established on Rojoa Island for Operation IVY was reactivated and constituted the only temporary camp operated at this atoll for CASTLE. Concurrent with the expanding scope of the Operation, the participating agencies submitted revisions to their personnel accomtmodation requirements. Accordingly, suitable adjustments in population densities at the various camp sites were made from time to time, and it is believed that the final prepara- tions for personnel accommodations were realistic in every way. As pre- viously indicated, however, the immediate aftereffects of the SHRIMP shot had an adverse effect upon the camp preparations at Bikini. Action for han- dling this emergency was largely guided by decisions arrived at in frequent meetings of key TG 7.5 and TG 7.1 personnel on the USS ESTES, where they were quartered at Bikini, and at Parry Island when Eniwetok action was involved, Other Task Groups andthe Task Force were represented or consulted as appropriate. Considering the emergency nature of the situation, it is thought that the actions taken by all concerned were commendable. It is believed, however, that if future planning properly anticipates loss of camp facilities, such as occurred in this Operation, some improvement in the nec- essary readjustments can be realized. 1.2 RECOMMENDATION In view of the experience referred to above and other adversities of lesser consequence, it is recommended that a joint effort be made by TG 7.5 and TG 7.1 to include in the camp planning for future operations procedures to be followed in the event of unanticipated camp abandonment. 1.3 POPULATION ANALYSIS In an effort to present CASTLE population trends at the PPG in a manner most useful to planning for future operations, it was deemed most practical 25
