He could not believe that the great Imperialist general, the right hand of the emperor, had any real intention of turning against his master.

Towards the end of January there was some excitement in Pilsen owing to the arrival there of all the generals of the Imperialist army save only Gallas, Coloredo, and Altringer.
Malcolm was sure that such a gathering could only have been summoned by Wallenstein upon some matter of the most vital importance, and he determined at all hazards to learn what was taking place, in order that he might enlighten Oxenstiern as to the real sentiments of the duke.
Learning that the principal chamber in the castle had been cleared, and that a meeting of the officers would take place there in the evening, he told Thekla when he went home to his meal at midday that she must not be surprised if he did not return until a late hour.

He continued his work until nearly six o'clock, the time at which the meeting was to begin, and then extinguishing his light, he made his way through the passages of the castle until he reached the council chamber, meeting with no interruption from the domestics, who were by this time familiar with his person, and who regarded him as one rising in favour with their master.
He waited in the vicinity of the chamber until he saw an opportunity for entering unobserved, then he stole into the room and secreted himself behind the arras beneath a table standing against the wall, and where, being in shadow, the bulge in the hanging would not attract attention.
In a few minutes he heard heavy steps with the clanking of swords and jingling of spurs, and knew that the council was beginning to assemble.
The hum of conversation rose louder and louder for a quarter of an hour; then he heard the door of the apartment closed, and knew that the council was about to commence.

The buzz of conversation ceased, and then a voice, which was that of Field Marshal Illo, one of the three men in Wallenstein's confidence, rose in the silence.

He began by laying before the army the orders which the emperor had sent for its dispersal to various parts of the country, and by the turn he gave to these he found it easy to excite the indignation of the assembly.
He then expatiated with much eloquence upon the merits of the army and its generals, and upon the ingratitude with which the emperor had treated them after their noble efforts in his behalf.
