That was in 1856, and as early as in 1857 the problem of Neuchâtel was again threatening us with war. This did not become generally known. In the spring of that year I was sent to Paris by the late king to negotiate with Emperor Napoleon concerning the passage of Prussian troops in an attack upon Switzerland. Everyone who hears this from me will know what this would have meant in case of an understanding, and that it could have become a far-reaching danger of war, and might have involved us with France as well as with other powers. Emperor Napoleon was not unwilling to agree. My negotiations in Paris, however, were terminated because his majesty the king in the meanwhile had come to an amicable understanding in the matter with Austria and Switzerland. But the danger of war, we must agree, was present also during that year. While I was on this mission in Paris, the Italian War hung in the air. It broke out a little more than a year later and came very near drawing us into a big general war of Europe. We went so far as to mobilize, and we should undoubtedly have taken the field, if the peace of Villafranca had not been concluded, somewhat prematurely for Austria, but just in time for ourselves, for we should have been obliged to wage this war under unfavorable circumstances. We should have turned this war, which was an Italian affair, into a Franco-Prussian war, and its cessation, outcome, and treaty of peace would no longer have depended on us, but on the friends and enemies who stood behind us. Thus we came into the sixties without the clouds of war having cleared from the horizon for even one single year.
