CHAPTER VI CASTLE ROLL-UP AND COSTS Roll-up for Operation CASTLE was a smoothly functioning procedure. The action making the Task Force a permanent organization, of course, tended to simplify the process for it was not necessary to close down completely all facilities following the termination of the test. Further, as has been explained relative to many of the problems and procedures of CASTLE, the experience of the previous overseas tests had made roll-up planning and execution a routine procedure. The final shot in the test series was detonated the morning of 14 May 1954, thus ending the operational phase of CASTLE. Roll- up and redeployment had begun in advance of this final shot so that the complete roll-up would be effected as expeditiously as possible after the conclusion of the Operation. As early as 16 February 1954, a letter from CJTF SEVEN to the task groups outlined specific roll-up policies. These were: 1. The Eniwetok garrison force would be reestablished. 2. Ships, aircraft, vehicles, and other equipment not required by the garrisom force would be returned to proper commands having custody. 3. Temporary duty personnel would be returned to their permanent duty stations. 4. All Bikini camps would be closed with: a. the LSD providing inter-island surface transportation 150
