One other remark we must make: this measure, as later events were to prove, was in some ways characteristic of all Bismarck's internal policy. Roon once complained of his strokes of genius, his unforeseen decisions. In foreign policy, bold and decisive as he could be, he was also cautious and prudent; to this he owes his success; he could strike when the time came, but he never did so unless he had tested the situation in every way; he never began a war unless he was sure to win, and he left nothing to chance or good fortune. In internal affairs he was less prudent; he did not know his ground so well, and he exaggerated his own influence. Moreover, in giving up the simpler Conservative policy of his younger years, he became an opportunist; he would introduce important measures in order to secure the support of a party, even though he might thereby be sacrificing the interests of his country to a temporary emergency. He really applied to home affairs the habits he had learned in diplomacy; there every alliance is temporary; when the occasion of it has passed by, it ceases, and leaves no permanent effect. He tried to govern Germany by a series of political alliances; but the alliance of the Government with a party can never be barren; the laws to which it gives birth remain. Bismarck sometimes thought more of the advantage of the alliance than of the permanent effect of the laws. Even after this there was still delay; there were the usual abortive attempts at a congress, which, as in 1859, broke down through the refusal of Austria to give way. There were dark intrigues of Napoleon, who even at the last moment attempted to divert the Italians from their Prussian alliance. In Germany there was extreme indignation against the man who was forcing his country into a fratricidal war. Bismarck had often received threatening letters; now an attempt was made on his life; as he was walking along _Unter den Linden_ a young man approached and fired several shots at him. He was seized by Bismarck, and that night put an end to his own life in prison. He was a South German who wished to save his country from the horrors of civil war. Moltke, now that all was prepared, was anxious to begin. Bismarck still hesitated; he was so cautious that he would not take the first step. At last the final provocation came, as he hoped it would, from Austria. He knew that if he waited long enough they would take the initiative. They proposed to summon the Estates of Holstein, and at the same time brought the question of the Duchies before the Diet. Bismarck declared that this was a breach of the Treaty of Gastein, and that that agreement was therefore void; Prussian troops were ordered to enter Holstein. Austria appealed for protection to the Diet, and moved that the Federal forces should be mobilised. The motion was carried by nine votes to seven. The Prussian Envoy then rose and declared that this was a breach of the Federal law;
