The Emperor was then still under the influence of our first peace offer so curtly rejected by the Entente. At the German Headquarters at Pless, where I arrived a few days later, I found the prevailing atmosphere largely influenced by the Entente's answer. Hindenburg and Ludendorff, who were apparently opposed to Burian's démarche for peace, merely remarked to me that a definite victory presented a possibility of ending the war, and the Emperor William said that he had offered his hand in peace but that the Entente had given him a slap in the face, and there was nothing for it now but war to the uttermost.

It was at this time that the question of the unrestricted U-boat warfare began to be mooted. At first it was the German Navy only, and Tirpitz in particular, who untiringly advocated the plan. Hohenlohe,[5] who, thanks to his excellent connections, was always very well informed, wrote, several weeks before the fateful decision was taken, that the German Navy was determined and bent on that aim. Bethmann and Zimmermann were both decidedly against it. It was entirely in keeping with the prudent wisdom of the former not to risk such experiments; Bethmann was an absolutely dependable, honourable and capable partner, but the unbounded growth of the military autocracy must be imputed to his natural tendency to conciliate. He was powerless against Ludendorff and little by little was turned aside by him. My first visit to Berlin afforded me the opportunity of thoroughly discussing the U-boat question with the Imperial Chancellor, and we were quite agreed in our disapproval of that method of warfare. At all events, Bethmann pointed out that such essentially military matters should in the first instance be left to military decision, as they alone were able to form a correct estimate of the result, and these reflections made me fear from the very first that all reasonable political scruples would be upset by military arguments. On this my first visit to Berlin, when this question naturally was the dominating one, the Chancellor explained to me how difficult his position was, because the military leaders, both on land and at sea, declared that if the unrestricted U-boat warfare were not carried out they would not be able to guarantee the Western front. They thus brought an iron pressure to bear on him, for how could he, the Chancellor, undertake to guarantee that the Western front could hold out? As a matter of fact, the danger of introducing the unrestricted U-boat campaign became greater and greater, and the reports sent by Hohenlohe left no doubt as to the further development of affairs in Berlin.

On January 12 he reported as follows:

The question of the extension of the U-boat warfare, as Your Excellency is aware from the last discussions in Berlin, becomes daily more acute.

On the one hand, all leading military and naval authorities insist on making use of this means as speedily as possible, as they declare it will end the war much more rapidly; on the other hand, all statesmen have grave fears as to what effect it will have on America and other neutrals.

The Supreme Military Command declares that a new offensive on a very large scale is imminent in the West and that the armies which are to resist this attack will not be able to understand why the navy should not do all that lies in its power to prevent, or at any rate to decrease, the reserves and ammunition being sent to our adversaries. The absence of co-operation on the part of the navy in the terrible battles the troops on the Western front will again have to face will have a most injurious effect on their moral.

The objections put forward as to the effect the proceeding might have on America are met in military circles by the assumption that America will take good care not to go to war; that she, in fact, would not be able to do so. The unfortunate failure of the United States military machine in the conflict with Mexico clearly proves what is to be expected from America in that respect. Even a possible breaking off relations with America does not necessarily signify war.

Meanwhile all the leading naval authorities reassert that they may be relied on, even though they are not considered capable of crushing England, at least to be able, before America can come in, so to weaken the British Island Empire that only one desire will be left to English politicians, that of seating themselves with us at the Conference table.

To this the Chancellor asked who would give him a guarantee that the navy was right and in what position should we find ourselves in case the admirals were mistaken, whereupon the Admiralty promptly asked what sort of position the Chancellor expected to find when autumn arrived without having made a proper use of the U-boats and we found ourselves, through exhaustion, compelled to beg for peace.

And thus the scales went up and down, weighing the chances for or against the U-boat war, and there was no possibility of positively determining which decision was the right one.
