Scope of Coverage

This volume presents documentation on the fourth and fifth conferences participated in by President Franklin D. Roosevelt and Prime Minister Winston S. Churchill after the United States became a belligerent in World War II. These are the Third Washington Conference of May 1943 and the First Quebec Conference of the following August. These conferences are also known by their code names: Trident for the Washington Conference and Quadrant for the meeting at Quebec. The Third Washington Conference was a single unit comprising two weeks of discussions in the capital. The First Quebec Conference, however, was accompanied by meetings at Hyde Park, New York, both before and after the Quebec meetings, and Churchill was a guest for more than a week in early September 1943 in the White House at Washington, where his presence gave rise to an ancillary series of meetings on problems related to the war. At both conferences there was participation in some meetings by Canadian and Chinese officials; and a meeting of the Pacific War Council was held during the Trident Conference.

Advisers, both civilian and military, assisted Roosevelt and Churchill at Washington and Quebec, but the predominant concerns of the conferences were military. Accordingly, the documentation on military subjects bulks large. But Secretary of State Cordell Hull participated to some extent in the conversations at Washington, and both Hull and Foreign Secretary Anthony Eden were major participants in the political discussions at Quebec, in preparation for which the Department of State assembled elaborate background documentation. Additional and extensive background information on the subjects discussed at the Washington and Quebec Conferences has previously been published in the annual volumes of Foreign Relations of the United States and in the series United States Army in World War II, published by the Department of the Army.

Organization of the Volume

The volume is divided into two parts, one devoted to each of the conferences. The organization of each of the parts is similar—pre-conference papers, minutes of meetings, and conference documents and [Page XVI] papers—but the greater bulk of documentation for the Quebec Conference and the desirability of including material on the related Hyde Park and Washington conversations dictated organization of the material into a larger number of chapters and a different arrangement of the pre-conference papers.

The volume opens with a section of previously unpublished papers on atomic energy in the period from February 1943 to the opening of the Third Washington Conference. This section is followed by a group of documents, arranged chronologically, on arrangements for the conference.

The chapter on proceedings of the Trident Conference (as is the case also with Quadrant ) is organized chronologically by meetings. Every meeting attended by a senior American official is accounted for. All minutes and memoranda of conversation are included; where none was found, the editors have supplied an editorial note, embodying what information was available on that particular meeting. There were no general meetings of the American delegation at either of the conferences; what little information has been found on President Roosevelt’s consultations with his advisers is included in the chapters on proceedings.

The Trident chapter entitled “Conference Documents and Supplementary Papers” contains the documents presented and discussed at the conference, together with related papers pertinent to conference subjects which were prepared during the period of the conference.

The preparatory papers for the First Quebec Conference, being much more numerous than those for the Third Washington Conference, are organized somewhat differently. They begin with a chapter on agenda and arrangements, followed by a chapter containing substantive preparatory papers, divided among sixteen subjects. This chapter includes pre-conference papers later circulated or discussed at the conference as well as official background memoranda and recommendations prepared specifically for possible use at Quebec.

The papers on the proceedings at Quebec (identical in scope and arrangement with the documentation on the Trident proceedings) are preceded in the volume by a brief chapter containing all the documentation found on the preliminary conversations between Roosevelt and Churchill which took place at Hyde Park, and by a log of the President’s visit to Canada. The chapter on proceedings is followed by the conference documents and related papers, arranged by subject, concluding with the final documents of the Quadrant Conference.

At the end of the First Quebec Conference, there was an interval of a week before Prime Minister Churchill arrived in Washington to resume his consultations with the President. A separate chapter is devoted [Page XVII] to the arrangements for the Prime Minister’s visit to the United States and to the developments in the war against Italy, then reaching a climax. Documentation on this subject during this period is included in this volume because it is needed to bridge the gap between the Quebec discussions and the signature of the Italian armistice, which took place while Churchill was in Washington. There is then a chapter on the proceedings of the conversations at Washington, followed by a chapter which includes the documents discussed during those conversations and related papers bearing directly on the President’s meetings with Churchill.

When Churchill left Washington, he stopped again briefly to see Roosevelt at Hyde Park, and the final chapter of the present volume includes all the documentation which has been found on their conversations there.

Unpublished Sources

Since the conferences at Washington and Quebec documented in this volume dealt to a very large extent with questions outside the jurisdiction of the Department of State, the editors sought and obtained the assistance of several other Government departments and agencies in gathering much of the source material for this publication. Of particular importance were the Presidential papers in the Franklin D. Roosevelt Library at Hyde Park, military papers in the files of the Department of Defense (principally in the files of the Joint Chiefs of Staff), and documents on cooperation with the United Kingdom in the field of atomic energy research in the files of the United States Atomic Energy Commission. The Roosevelt Library provided photocopies of all Presidential papers (including the papers of Harry L. Hopkins) that could be found relating to either of the conferences. The Department of Defense provided all papers that could be found documenting the official position or advice of the War and Navy Departments on politico-military subjects discussed at the international level, as presented by the civilian leaders of those departments and by the Joint Chiefs of Staff and the Combined Chiefs of Staff.

The papers printed in this volume which are in the Central Files of the Department of State are indicated by means of a file number in the headnote, in the usual style of Foreign Relations. The provenance of papers obtained from other sources is also shown in headnotes, as indicated on the following list:

b. unofficial

Much authoritative information is to be found in unofficial publications written by those who participated in the conferences (or in matters closely related to the conferences) or by authors who have used the papers of conference participants. In view of the incompleteness of the official record, in many respects, for the conferences presented in this volume, the editors have cited such unofficial publications frequently for factual information not found in official files. The Department of State assumes no responsibility for the accuracy of fact or [Page XXI] interpretation in these unofficial publications.

Editorial Treatment

In the preparation of this volume the editors have been guided by the regulations of the Department applicable to the Foreign Relations series, viz.:

1350 Documentary Record of American Diplomacy

1351 Scope of Documentation

The publication Foreign Relations of the United States constitutes the official record of the foreign policy of the United States. These volumes include, subject to necessary security considerations, all documents needed to give a comprehensive record of the major foreign policy decisions within the range of the Department of State’s responsibilities, together with appropriate materials concerning the facts which contributed to the formulation of policies. When further material is needed to supplement the documentation in the Department’s files for a proper understanding of the relevant policies of the United States, such papers should be obtained from other Government agencies.

1352 Editorial Preparation

The basic documentary record to be printed in Foreign Relations of the United States shall be edited by the Historical Office, Bureau of Public Affairs of the Department [Page XXIII] of State. The editing of the record shall be guided by the principles of historical objectivity. There shall be no alteration of the text, no deletions without indicating where in the text the deletion is made, and no omission of facts which were of major importance in reaching a decision. Nothing shall be omitted for the purpose of concealing or glossing over what might be regarded by some as a defect of policy. However, certain omissions of documents are permissible for the following reasons.

To avoid publication of matters which would tend to impede current diplomatic negotiations or other business.
To condense the record and avoid repetition, of needless details.
To preserve the confidence reposed in the Department by individuals and by foreign governments.
To avoid giving needless offense to other nationalities or individuals.
To eliminate personal opinions presented in despatches and not acted upon by the Department. To this consideration there is one qualification—in connection with major decisions it is desirable, where possible, to show the alternatives presented to the Department before the decision was made.

1353 Clearance

To obtain appropriate clearances of material to be published in Foreign Relations of the United States, the Historical Office:

Refers to the appropriate policy offices of the Department and of other agencies of the Government such papers as appear to require policy clearance.
Refers to the appropriate foreign governments requests for permission to print as part of the diplomatic correspondence of the United States those previously unpublished documents which were originated by the foreign governments.
