"I am authorised to give an assurance that, if the German fleet comes into the Channel or through the North Sea to undertake hostile operations against French coasts or shipping, the British fleet will give all the protection in its power.
"This assurance is of course subject to the policy of His Majesty's Government receiving the support of Parliament, and must not be taken as binding His Majesty's Government to take any action until the above contingency of action by the German fleet takes place."
I pointed out that we had very large questions and most difficult issues to consider, and that Government felt that they could not bind themselves to declare war upon Germany necessarily if war broke out between France and Germany to-morrow, but it was essential to the French Government, whose fleet had long been concentrated in the Mediterranean, to know how to make their dispositions with their north coast entirely undefended. We therefore thought it necessary to give them this assurance. It did not bind us to go to war with Germany unless the German fleet took the action indicated, but it did give a security to France that would enable her to settle the disposition of her own Mediterranean fleet.
M. Cambon asked me about the violation of Luxemburg. I told him the doctrine on that point laid down by Lord Derby and Lord Clarendon in 1867. He asked me what we should say about the violation of the neutrality of Belgium. I said that was a much more important matter; we were considering what statement we should make in Parliament to-morrow—in effect, whether we should declare violation of Belgian neutrality to be a casus belli. I told him what had been said to the German Ambassador on this point.
No. 153.
Sir Edward Grey to Sir E. Goschen.
(Telegraphic.) Foreign Office, August 4, 1914.
The King of the Belgians has made an appeal to His Majesty the King for diplomatic intervention on behalf of Belgium in the following terms:—
"Remembering the numerous proofs of your Majesty's friendship and that of your predecessor, and the friendly attitude of England in 1870 and the proof of friendship you have just given us again, I make a supreme appeal to the diplomatic intervention of your Majesty's Government to safeguard the integrity of Belgium."
His Majesty's Government are also informed that the German Government has delivered to the Belgian Government a note proposing friendly neutrality entailing free passage through Belgian territory, and promising to maintain the independence and integrity of the kingdom and its possessions at the conclusion of peace, threatening in case of refusal to treat Belgium as an enemy. An answer was requested within twelve hours.
