His actions were so problematical, indeed, that suspicion of his motives grew more decided, and at length a secret conspiracy was raised against him with the connivance of the emperor.  Wallenstein, as if fearful of an attempt to rob him of his power, had his superior officers assembled at a banquet given at Pilsen, in January, 1634.  A fierce attack of gout prevented him from presiding, but his firm adherents, Field-Marshals Illo and Terzka, took his place, and all the officers signed a compact to adhere faithfully to the duke in life and death as long as he should remain in the emperor’s service.  Some signed it who afterwards proved false to him, among them Field-Marshal Piccolomini, who afterwards betrayed him.

Just what designs that dark and much revolving man contemplated it is not easy to tell.  It may have been treachery to the emperor, but he was not the man to freely reveal his secrets.  The one person he trusted was Piccolomini, whose star seemed in favorable conjunction with his own.  To him he made known some of his projected movements, only to find in the end that his trusted confidant had revealed them all to the emperor.

The plot against Wallenstein was now put into effect, the emperor ordering his deposition from his command, and appointing General Gablas to replace him, while a general amnesty for all his officers was announced.  Wallenstein was quickly taught how little he could trust his troops and officers.  Many of his generals fell from him at once.  A few regiments only remained faithful, and even in their ranks traitors lurked.  With but a thousand men to follow him he proceeded to Eger, and from there asked aid of Bernhard of Weimar, as if he purposed to join with those against whom he had so long fought.  Bernhard received the message with deep astonishment, and exclaimed, moved by his belief that Wallenstein was in league with the devil,—­

“He who does not trust in God can never be trusted by man!”

The great soldier of fortune was near his end.  The stars were powerless to save him.  It was not enough to deprive him of his command, his enemies did not deem it safe to let him live.  One army gone, his wealth and his fame might soon bring him another, made up of those mercenary soldiers of all nations, and of all or no creeds, who would follow Satan if he promised them plunder.  His death had been resolved upon, and the agent chosen for its execution was Colonel Butler, one of the officers who had accompanied him to Eger.

It was late in February, 1634.  On the night fixed for the murder, Wallenstein’s faithful friends, Illo, Terzka, Kinsky, and Captain Neumann were at a banquet in the castle of Eger.  The agents of death were Colonel Butler, an Irish officer named Lesley, and a Scotchman named Gordon, while the soldiers employed were a number of dragoons, chiefly Irish.

In the midst of the dinner the doors of the banqueting hall were burst open, and the assassins rushed upon their victims, killing them as they sat, with the exception of Terzka, who killed two of his assailants before he was despatched.
