DRAFT i Department of Energy History Division researched the DOE Executiv Secretariatfiles. Mr. L. Joe Deal and Mr. Roger Ray made available to us document their personalfiles. materials from It was not possible in the time available to do an exhaustive search of DOE/ERDA/AEC records, although we believe that major developm@nts involving the agency have been covered. No effort was made, with the constrdints of time and funds, to examine records from other agencies involved in the Marshall Islands except as documents from these agencies were found in DOEfiles. For the chronology to be complete, we suggest searching, at the very least, the records of the Departments of the Interior, State, and Defense relating to the history of U.S. involvementin the Marshall Islands. Appendices have been included to assist the user of the chronology--a summary of the terms of the Compact of Free Association and of fits implementing agreementof relevance to the DOE,lists of officials and groups concerned with the administration of the Marshall tslands, a list of abbreviations and acronyms used in the chronology, and a series of maps showing the Marshall Islands dnd the individual atolls affected by nuclear testing. Also included are a map off U.S. Navy ship positions after Castle Bravo and a map showing relocations offthe Marshallese through May 1954. Copies of the cited documents have been provided. Th¢ documents are identified by alphanumeric designations, which are included in bracHets following the citation in the endnote. When the relevant information is containgd in one part of a larger document, the cited information has been indicated with a dark line in the left margin of the document.
