"Here is my hand," said the Elector solemnly. "Swear upon this hand hereafter to become the sword of Brandenburg, to serve me faithfully and zealously, and to have no other Sovereign than myself!" "In God's name I swear that I will have no other Sovereign, and serve under no other Prince, than yourself alone, the Elector of Brandenburg!" cried Burgsdorf, laying both his hands in that of the Elector and pressing it fervently to his lips. "And now, having sworn you into my service," said the Elector, in a majestic tone, "now I commission you to return home to Küstrin and to administer the oath to all the officers and men there. But understand, to me alone, not to the Emperor." "To you alone, not to the Emperor!" cried Burgsdorf, with animation. "And I further order you to receive no imperial garrison into your fortress, for we have a right to exact this, since it is clearly stipulated in the peace of Prague that each Prince is at liberty to man his fortresses with his own people, which clause gives validity to this assertion of right."[39] "Your Electoral Highness!" cried Burgsdorf, "that was spoken like a man! Begin the good work in earnest, and command the Stadtholder without delay to swear in the other governors of your remaining fortresses!"[40] "You are of opinion, then, that this is very necessary, and that these gentlemen might refuse to swear allegiance to me alone?" "Yes, sir, I am strongly of that opinion, and would venture to lay a wager that Colonel von Rochow at Spandow, and Goldacker and Kracht in Berlin, will not take oath to your Electoral Highness." "Woe to them if they do it not!" cried the Elector, with flashing eyes. "I shall prove to them that they must bow in obedience to me, and that I recognize no other lord but myself within the limits of my own dominions. Now go back to the Mark, Burgsdorf, and do as I have bidden you. You may also, as would once have been so pleasant to you, go over right often to Berlin. Attend well to all that is going on, for it may be that I shall soon have occasion for you there. Be on your guard, therefore, colonel, and be pretty circumspect in word and deed. Ponder upon the advice given you by the little Electoral Prince once: 'Learn and wait.'" "Sir, you give me another thrust!" cried Burgsdorf; "but it does me good, and I am glad of it. Yes, I shall learn and wait, for I see plainly the last night of the world has not come yet, and my dearest master will not always have to act so on the defensive as now; when the right time comes, he will strike and prove to all his enemies, even the mightiest of them, that he is more powerful than they. Mark now, mark my words; Schwarzenberg may look out!" "But meanwhile let Burgsdorf look out! Farewell now, Burgsdorf, you have received my orders. Execute them."
