When we held Grand Manœuvres we were very careful to arrange the coaling and leave which followed in such a way as to secure us the power of meeting any blow which could possibly reach us in a given time. I know of no moment in the period of which I am writing up to the declaration of war in which it was physically possible for the British Fleet to have been surprised or caught dispersed and divided by any serious German force of surface vessels. An attempt in full peace to make a submarine attack upon a British squadron in harbour or exercising, or to lay mines in an area in which they might be expected to exercise, could not wholly be provided against; but in all human probability its success would only have been partial. Further, I do not believe that such treachery was ever contemplated by the German Admiralty, Government or Emperor. While trying as far as possible to guard against even the worst possibilities, my own conviction was that there would be a cause of quarrel accompanied by a crisis and a fall in markets, and followed very rapidly by a declaration of war, or by acts of war intended to be simultaneous with the declaration, but possibly occurring slightly before. What actually did happen was not unlike what I thought would happen. Early in 1912, the Prime Minister set up again, under his own chairmanship, the Invasion Committee of the Committee of Imperial Defence.
