30 August, 1911.
Perhaps the time is coming when decisive action will be necessary. Please consider the following policy for use if and when the Morocco negotiations fail.
Propose to France and Russia a triple alliance to safeguard (inter alia) the independence of Belgium, Holland, and Denmark.
Tell Belgium that, if her neutrality is violated, we are prepared to come to her aid and to make an alliance with France and Russia to guarantee her independence. Tell her that we will take whatever military steps will be most effective for that purpose. But the Belgian Army must take the field in concert with the British and French Armies, and Belgium must immediately garrison properly Liège and Namur. Otherwise we cannot be responsible for her fate.
Offer the same guarantee both to Holland and to Denmark contingent upon their making their utmost exertions.
We should, if necessary, aid Belgium to defend Antwerp and to feed that fortress and any army based on it. We should be prepared at the proper moment to put extreme pressure on the Dutch to keep the Scheldt open for all purposes. If the Dutch close the Scheldt, we should retaliate by a blockade of the Rhine.
It is very important to us to be able to blockade the Rhine, and it gets more important as the war goes on. On the other hand, if the Germans do not use the “Maestricht Appendix” in the first days of the war, they will not want it at all.
Let me add that I am not at all convinced about the wisdom of a close blockade, and I did not like the Admiralty statement. If the French send cruisers to Mogador and Saffi, I am of opinion that we should (for our part) move our main fleet to the north of Scotland into its war station. Our interests are European, and not Moroccan. The significance of the movement would be just as great as if we sent our two ships with the French.
Please let me know when you will be in London; and will you kindly send this letter on to the Prime Minister.
My views underwent no change in the three years of peace that followed. On the contrary they were confirmed and amplified by everything I learned. In some respects, as in the abolition of the plan of close blockade and the sending of the Fleet to its war station, I was able to carry them out. In other cases, such as the defence of Antwerp, I had not the power to do in time what I believed to be equally necessary. But I tried my best, not, as has frequently been proclaimed, upon a foolish impulse, but in pursuance of convictions reached by pondering and study. I could not help feeling a strong confidence in the truth of these convictions, when I saw how several of them were justified one after the other in that terrible and unparalleled period of convulsion. I had no doubts whatever what ought to be done in certain matters, and my only difficulty was to persuade or induce others.
