Report to the President and Prime Minister of the Agreed Summary of Conclusions Reached by the Combined Chiefs of Staff at the ARGONAUT Conference
The agreed summary of the conclusions reached at ARGONAUT Conference is submitted herewith:
Overall Objective
In conjunction with Russia and other Allies, to bring about at the earliest possible date the unconditional surrender of Germany and Japan.
Overall Strategic Concept for the Prosecution of the War
In cooperation with Russia and other Allies, to bring about at the earliest possible date the unconditional surrender of Germany.
Simultaneously, in cooperation with other Pacific Powers concerned, to maintain and extend unremitting pressure against Japan with the purpose of continually reducing her military power and attaining positions from which her ultimate surrender can be forced. The effect of any such extension on the overall objective to be given consideration by the Combined Chiefs of Staff before action is taken.
Upon the defeat of Germany, in cooperation with other Pacific Powers and with Russia, to direct the full resources of the United States and Great Britain to bring about at the earliest possible date the unconditional surrender of Japan.
Basic Undertakings in Support of Overall Strategic Concept
Whatever operations are decided on in support of the overall strategic concept, the following established undertakings will be a first charge against our resources, subject to review by the Combined Chiefs of Staff in keeping with the changing situation:
a. Maintain the security and warmaking capacity of the Western Hemisphere and the British Isles.
b. Support the warmaking capacity of our forces in all areas.
c. Maintain vital overseas lines of communication.
d. Continue the disruption of enemy sea communications.
e. Continue the offensive against Germany.
f. Undertake such measures as may be necessary and practicable to aid the war effort of Russia to include coordinating the action of forces.
g. Undertake such measures as may be necessary and practicable in order to aid the war effort of China as an effective ally and as a base for operations against Japan.
h. Provide assistance to such of the forces of the liberated areas in Europe as can fulfill an active and effective role in the war against Germany and/or Japan. Within the limits of our available resources to assist other co-belligerents to the extent they are able to employ this assistance against the Enemy Powers in the present war. Having regard to the successful accomplishment of the other basic undertakings, to provide such supplies to the liberated areas as will effectively contribute to the war-making capacity of the United Nations against Germany and/or Japan.
i. Reorient forces from the European Theater to the Pacific and Far East as a matter of highest priority having regard to other agreed and/or inescapable commitments as soon as the German situation allows.
j. Continue operations leading to the earliest practicable invasion of Japan.
Execution of the Overall Strategic Concept
Defeat of Germany
The U-Boat War
We are concerned with the possibility that German U-boats may again constitute a serious threat to our North Atlantic shipping lanes. It is too early yet to assess the extent to which such an offensive could achieve success, and we propose to review the matter again on 1 April 1945.
Meanwhile, we have agreed on the following countermeasures:
a. To build up as much as is practicable the strength of surface hunting groups and anti-U-boat air squadrons.
b. To maintain and, if possible, increase “marginal” bomber effort on assembly yards, concentrating as far as is practicable against Hamburg and Bremen.
c. To maintain “marginal” effort against operating bases, being ready to increase this when bases become crowded beyond the capacity of concrete pens.
d. To increase, by 100% if possible, the air mining effort against U-boats, including the training areas.
e. To mine waters beyond range of d. above by using surface minelayers and carrier-borne aircraft.
f. To intensify operations against enemy minesweepers.
g. To maintain and intensify operations against the enemy shipping used to supply U-boat bases.
Operations in Northwest Europe
In two telegrams, SCAF 180 as amended by SCAF 194, the Supreme Commander, Allied Expeditionary Force, has presented his appreciation and his plan of operations for Northwest Europe. His plan is as follows:
a. To carry out immediately a series of operations north of the Moselle with a view to destroying the enemy and closing the Rhine north of Düsseldorf.
b. To direct our efforts to eliminating other enemy forces west of the Rhine, which still constitute an obstacle or a potential threat to our subsequent Rhine crossing operations.
c. To seize bridgeheads over the Rhine in the North and the South.
d. To deploy east of the Rhine and north of the Ruhr the maximum number of divisions which can be maintained (estimated at some 35 divisions). The initial task of this force, assisted by air action, will be to deny to the enemy the industries of the Ruhr.
e. To deploy east of the Rhine, on the axis Frankfurt-Kassel, such forces, if adequate, as may be available after providing 35 divisions for the North and essential security elsewhere. The task of this force will be to draw enemy forces away from the North by capturing Frankfurt and advancing on Kassel.
We have taken note of SCAF 180 as amended by SCAF 194 and of the Supreme Commander’s assurance that he will seize the Rhine crossings in the North just as soon as this is a feasible operation and without waiting to close the Rhine throughout its length. Further, that he will advance across the Rhine in the North with maximum strength and complete determination, immediately the situation in the South allows him to collect the necessary forces and do this without incurring unreasonable risks.
Strategy in the Mediterranean
We have reviewed our strategy in the Mediterranean in the light of the development of the situation in Europe and of the fact that the enemy is at liberty at any time to make a voluntary withdrawal in Italy. We have agreed that our primary object in the war against Germany should be to build up the maximum possible strength on the Western Front and to seek a decision in that theater.
In accordance with this concept we have agreed to withdraw certain forces from the Mediterranean Theater and to place them at the disposal of the Supreme Commander, Allied Expeditionary Force, and to redefine the tasks of the Supreme Allied Commander, Mediterranean.
Our proposals are contained in the directive to the Supreme Allied Commander, Mediterranean, attached as Appendix “A.”
The War Against Japan
Overall Objective in the War Against Japan
We have agreed that the overall objective in the war against Japan should be expressed as follows:
To force the unconditional surrender of Japan by:
a. Lowering Japanese ability and will to resist by establishing sea and air blockades, conducting intensive air bombardment, and destroying Japanese air and naval strength.
b. Invading and seizing objectives in the industrial heart of Japan.
Operations in the Pacific Area
We have taken note of the plans and operations proposed by the United States Chiefs of Staff in CCS 417/11 (Appendix “B”).
Operations in Southeast Asia Command
We have agreed to the following policy in respect of employment in Southeast Asia Command of United States resources deployed in the India-Burma Theater:
a. The primary military object of the United States in the China and India-Burma Theaters is the continuance of aid to China on a scale that will permit the fullest utilization of the area and resources of China for operations against the Japanese. United States resources are deployed in India-Burma to provide direct or indirect support for China. These forces and resources participate not only in operating the base and the line of communications for United States and Chinese forces in China, but also constitute a reserve immediately available to China without permanently increasing the requirements for transport of supplies to China.
b. The United States Chiefs of Staff contemplate no change in their agreement to SACSEA’s use of resources of the U.S. India-Burma Theater in Burma when this use does not prevent the fulfillment of their primary object of rendering support to China including protection of the line of communications. Any transfer of forces engaged in approved operations in progress in Burma which is contemplated by the United States Chiefs of Staff and which, in the opinion of the British Chiefs of Staff, would jeopardize those operations, will be subject to discussion by the Combined Chiefs of Staff.
We have reviewed the progress of the campaign in Burma and agreed upon the terms of a directive to the Supreme Allied Commander, Southeast Asia. This directive is attached as Appendix “C.”
Planning Dates for the End of the War Against Germany and Japan
We feel that it is important to agree and promulgate planning dates for the end of the war against Germany and Japan. These dates are necessary for the purpose of planning production and the allocation of manpower.
We recommend that the planning dates for the end of the war against Germany should be as follows:
a. Earliest date – 1 July 1945.
b. Date beyond which the war is unlikely to continue – 31 December 1945.
We recommend that the planning date for the end of the war against Japan should be set at 18 months after the defeat of Germany.
All the above dates to be adjusted periodically to conform to the course of the war.
Shipping
We have reviewed the over-all cargo and troop shipping position for the remainder of 1945 under the assumption that Germany is defeated on 1 July 1945.
For the first half of 1945 the principal difficulty will be with cargo shipping, which will be tight and in which deficits will approach unmanageable proportions until V-E Day. We have issued instructions to theater commanders to exercise strict control of shipping and have agreed that deficits should be adjusted in accordance with the following principles:
In the event of a deficit in shipping resources, first priority should be given to the basic undertakings in support of the over-all strategic concepts as agreed in ARGONAUT.
So long as these first priority requirements are not adequately covered, shipping for other requirements will not be allocated without prior consultation with the appropriate Chiefs of Staff.
For the second half of 1945 the principal difficulty will be troop shipping, which will become particularly acute in the last quarter of the year. We have agreed that the matter should be reviewed and a report submitted to the Combined Chiefs of Staff not later than 1 April 1945. This report will take account, from the shipping point of view, of the possibility that the war against Germany may continue beyond 1 July 1945.
Oil
We have reviewed and agreed upon the levels of stocks of all petroleum products that should be maintained in all theaters. The text of our agreement is attached as Appendix “D.”
Equipment for Allied and Liberated Forces
The Supreme Allied Commander, Mediterranean, has submitted proposals (NAF 841) designed to assist the Greek Government in forming their own army and so releasing British forces for employment elsewhere.
We have agreed that the British Chiefs of Staff should proceed to implement the Supreme Commander’s proposals, on the understanding that this will not interfere with the provision of equipment for Allied and liberated forces in Northwest Europe, nor result in subsequent direct or indirect charges against United States resources.
Appendix “A”
Directive to SAC, Mediterranean, Repeated to SCAEF
It is our primary intention in the war against Germany to build up the maximum possible strength on the Western Front and to seek a decision in that theater. We have, therefore, reviewed your directive and decided as follows:
Greece
The earliest possible discharge of British obligations in Greece must be your constant aim.
The object of British presence and operations in Greece is to secure that part of Greece which is necessary for the establishment of the authority of a free Greek Government.
This object must always be regarded in the light of the paramount need for releasing troops from Greece for use against the Germans. You should, therefore, concentrate on building up a Greek force on a national basis as soon as possible.
Italy
In pursuance of the policy given in paragraph 1, it has been decided to withdraw from your theater to the Western Front up to five divisions (of which not more than two should be armored) as follows:
a. At the earliest possible date three Allied divisions drawn from the Allied Armies in Italy.
b. Further complete formations as the forces now in Greece are released from that country.
c. It is intended to withdraw Canadian and British divisions. The nomination of ground formations to be withdrawn and the arrangements for their transfer will form the subject of a separate instruction. The program will be agreed between you and Supreme Commander, Allied Expeditionary Force, and approved by the Combined Chiefs of Staff before any moves take place.
Air Forces
Two fighter groups of Twelfth Air Force will be moved to France at once. Combined Chiefs of Staff intend to move to France in the near future as much of the Twelfth Air Force as can be released without hazard to the accomplishment of your mission. You should consult with SCAEF and submit agreed proposals for confirmation by the Combined Chiefs of Staff.
There will be no significant withdrawal of amphibious assault forces.
We recognize that these withdrawals will affect the scope of your operations in the Italian Theater. We, therefore, redefine your objects as follows:
a. Your first object should be to ensure that, subject to any minor adjustments you may find necessary, the front already reached in Italy is solidly held.
b. Within the limits of the forces remaining available to you after the withdrawals in paragraph 4 above have been effected, you should do your utmost, by means of such limited offensive action as may be possible and by the skillful use of cover and deception plans, to contain the German forces now in Italy and prevent their withdrawal to other fronts.
c. You should, in any case, remain prepared to take immediate advantage of any weakening or withdrawal of the German forces.
Adriatic
Subject to the requirements of the Italian Theater, you should continue to give all possible support to the Yugoslav Army of National Liberation, until the territory of Yugoslavia has been completely cleared. You will carry out such minor operations on the eastern shores of the Adriatic as your resources allow.
Appendix “C”
Directive to SAC, Southeast Asia
Your first object is to liberate Burma at the earliest date. (To be known as operation LOYALIST).
Subject to the accomplishment of this object, your next main task will be the liberation of Malaya and the opening of the Straits of Malacca (To be known as operation BROADSWORD).
In view of your recent success in Burma, and of the uncertainty of the date of the final defeat of Germany, you must aim at the accomplishment of your first object with the forces at present at your disposal. This does not preclude the dispatch of further reinforcements from the European Theater should circumstances make this possible.
You will prepare a program of operations for the approval of the Combined Chiefs of Staff.
In transmitting the foregoing directive the Combined Chiefs of Staff direct your attention to the agreed policy in respect of the use in your theater of United States resources deployed in the India-Burma Theater (see paragraph 16 of the Report).
