The British Chargé (Campbell) to the Secretary of State

My Dear Mr. Secretary: I venture to send you herewith an aide-mémoire on the subject of the difference of opinion between the Italian Government and His Majesty’s Government in the United Kingdom on the one hand and the French Government on the other regarding the interpretation of the “bases of agreement” of March 1st last relative to naval construction. The aide-mémoire contains the considerations my Government instructed me to lay before you. It explains why His Majesty’s Government and the Italian Government consider [Page 412] their interpretation to be correct, and also—which is more important—why neither the French interpretation nor the French proposal of April 20th, (with which you are familiar) could be accepted by His Majesty’s Government.

It also goes into the reasons why a four year agreement of the kind concerning which the United States Ambassador made enquiries of the First Lord of the Admiralty on May 2nd could not be accepted.

I hope you may find the aide-mémoire useful pending your discussions with Mr. Morrow.

Meanwhile there are one or two points arising out of the subject matter and our conversation yesterday20 which I should much like to have an opportunity of discussing with you.

Believe me [etc.]

Ronald Campbell

Aide-Mémoire

The difference of opinion between the Italians and Great Britain on the one hand and the French on the other regarding the interpretation of the bases of agreement for a settlement of the problems left outstanding by the London Naval Conference relates to the date at which France may start replacement of a certain proportion of the overage tonnage which it had been agreed by all three parties should remain overage for the period of the agreement. France now maintains that the limitation that she has accepted in respect of new construction relates only to tonnage to be completed by December 31st, 1936, which means that she would be free to start the replacement of her retained overage tonnage in 1935 and 1936. His Majesty’s Government and the Italians maintain on the other hand that it was clearly agreed between all parties that the last sentence of Article 19 in Part III of the Treaty of London: (which reads, i. e. “Nevertheless, replacement tonnage may be laid down for cruisers and submarines that become over age in 1937, 8 and 9, and for destroyers that become overage in 1937 and 8.”) was to be incorporated in the new agreement as one of the “provisions which are of general application” mentioned in paragraph C. a. 2 of the bases of agreement. The effect of this understanding would be that the tonnage which France and Italy could lay down in 1935 and 1936 would be limited to tonnage in replacement of ships becoming overage in 1937, 38 and 39. The correctness of the British and Italian point of view is borne out by the last sentence of the bases of agreement: i. e. “It is understood that the present arrangement establishes no permanent ratio in any category of ship as between the members of the British Empire, France and Italy. In [Page 413] particular no precedent is being created for the final solution of the question whether and if so in what manner tonnage remaining over age on December 31st, 1936 may be ultimately replaced”.

The proposal for a settlement made in the last French memorandum was in effect no advance at all on the French position explained above, since it would be still possible for France to complete in the first four years the agreed whole construction which under the British and Italian interpretation should be spread over six years, and thus be free to lay down any tonnage she pleased in 1935 and 1936 failing agreement at the 1935 conference. The fact that in their last memorandum the French Government undertook not to start laying down any of this replacement tonnage before July 1935 would not affect France’s capacity to lay down a whole year’s programme between July and December, 1935.

The tonnage of new construction accorded to France under the agreement is 165, 304 tons made up as follows: tonnage to be completed by December 31st, 1936, 136, 438 tons. Tonnage which may be laid down but not completed before December 31st, 1936 (A) capital ships:—23, 333 tons. (B) Tonnage in replacement ships becoming overage in 1937 and 1938 and 1939: 5,533 tons.

According to the Anglo-Italian view the above total, amounting to 165, 304 tons, is the total that France would have the right to lay down in the six years, making 27, 500 tons a year. Under the last French proposal France would be able to concentrate this tonnage into four years, making 41,000 tons a year.

In the British reply to the French memorandum His Majesty’s Government have suggested a formula making it clear that it would be for the conference of 1935 to consider whether France and Italy can be authorized to lay down further tonnage in the year 1936; failing agreement by the conference on that point however the laying down of new construction by France and Italy would remain limited for six years to the 165,000 tons above mentioned.

The Italian reply to the French memorandum was on May 3rd expected shortly at the Foreign Office. Meanwhile they had been informed semi-officially that the Italian Government agrees to the compromise proposal put forward by His Majesty’s Government.

It will be seen that acceptance of the French proposal would have involved the construction by France during the first four years of the Treaty of 13, 500 tons a year more than His Majesty’s Government, who had gone to the utmost limit of concession in the bases of agreement, had agreed to thereunder, and that in addition France would have been able to lay down what she pleased in the years 1935 and 1936 while His Majesty’s Government remained bound under Part III of the London Treaty. It is clear that His Majesty’s Government could not have been expected to accept this proposal.

[Page 414]

On May 2nd the United States Ambassador in London informed the First Lord of the Admiralty that he had had an enquiry from his government as to whether any suggestion had been considered in London to the effect that the bases of agreement might be re-worded so as to provide for limitation of the laying down of tonnage instead of providing for limitation of completed tonnage, the entire agreement to be made to end in July 1935.

In the above connection it must be borne in mind that the idea of limiting construction programmes purely and simply, was tried during the negotiations at Geneva last November and, as will be remembered, had to be discarded for following reasons:—

1.
The Italians held that in any such plan they would have to demand an annual construction programme which would be at least as high as the French programme for fear of compromising the principle of parity. This the French would not concede.
2.
The annual programme demanded by France was too high to make it worth while for Italy to enter an agreement on such a basis.

To revert to this idea now would mean abandoning that part of the bases of agreement on which all sides are agreed (namely tonnage which may be completed by December 31st, 1936) without getting us any nearer to a settlement of the difficulty concerning the amount of tonnage which may be laid down during that period.

In reply to General Dawes enquiry moreover the First Lord gave His Excellency his purely personal opinion as to the feasibility of the suggestion from a British point of view. It was as follows:—

[Here follows the text of the statement transmitted in telegram No. 131, May 2, 9 p.m., from the Ambassador in Great Britain, printed on page 406.]

The First Lord of the Admiralty added to General Dawes that an actual agreement to give France such a large construction in such a short period would greatly encourage all the smaller powers to ask for more tonnage at Geneva and that these had in certain instances already indicated that their demands would represent expansion.
