It was a severe strain on his loyalty, but he withstood it; he has, I believe, never expressed his opinion about the King; we can guess what it must have been. It was a melancholy picture: a King violent and timid, obstinate and irresolute; his will dragged now this way, now that, by his favourites, his wife and his brother; his own Ministers intriguing against each other; ambassadors recommending a policy instead of carrying out their instructions; and the Minister-President standing calmly by, as best he could, patching up the appearance of a Consistent policy.
It was probably the experience which he gained at this time which in later years, when he himself had become Minister, made Bismarck so jealous of outside and irresponsible advisers; he did not choose to occupy the position of Manteuffel, he laid down the rule that none of his own subordinates should communicate with the King except through himself; a Bismarck as Foreign Minister would not allow a Gerlach at Court, nor a Bismarck among his envoys. He had indeed been careful not to intrigue against his chief, but it was impossible to observe that complete appearance of acquiescence which a strong and efficient Minister must demand. Bismarck was often asked his opinion by the King directly; he was obliged to say what he believed to be the truth, and he often disapproved of that which Manteuffel advised. In order to avoid the appearance of disloyalty, he asked Gerlach that his letters should be shewn to Manteuffel; not all of them could be shewn, still less would it be possible to repeat all he said. If they were in conflict, his duty to the King must override his loyalty to the Minister, and the two could not always be reconciled. To Englishmen indeed it appears most improper that the King should continually call for the advice of other politicians without the intervention or the knowledge of his Ministers, but this is just one of those points on which it is impossible to apply to Prussian practice English constitutional theory. In England it is a maxim of the Constitution that the sovereign should never consult anyone on political matters except the responsible Ministry; this is possible only because the final decision rests with Parliament and the Cabinet and not with the sovereign. It was, however, always the contention of Bismarck that the effective decision in Prussia was with the King. This was undoubtedly the true interpretation of the Prussian Constitution; but it followed from this that the King must have absolute freedom to ask the advice of everyone whose opinions would be of help to him; he must be able to command the envoys to foreign countries to communicate with him directly, and if occasion required it, to consult with the political opponents of his own Ministers. To forbid this and to require that all requests should come to him by the hands of the Ministers would be in truth to substitute ministerial autocracy for monarchical government.
