His marriage to widow Anna Albertine of Rziczan countess of Furstenberg, strengthened his ties with the Bohemian political elite represented by the Trczka and Kinsky families, while the estates of Olbramowitz and Drazkow were added to his possessions.

In the spring of 1625, Ilow was recalled into active service campaigning in Hessen and Nassau, where his riders gained infamy for their plundering and violent demeanor.

In a letter towards Karl von Harrach, Wallestein states that the reason behind this decision was his resentment for Ilow whom he characterized as vain and gossipy.

On 27 November 1627, Ilow was present at Ferdinand III's crowning as king of Bohemia, he used the occasion in order to showcase his new coat of arms which bore an imperial laurel wreath.

He accompanied the Generalissimo in his pursuit of Hans Georg von Arnim-Boitzenburg in the vicinity of Forst, he was then sent back to Lusatia, recapturing Görlitz on 30 October, following a costly engagement.

His dislike of courtly life and the influence exerted by the church upon the emperor created an axis of undercover opposition that launched a smear campaign against him.

Numerous commanders signed the Reverse so as not to arouse suspicion, while at the same time a party centered around Ottavio Piccolomini began circulating an anonymous tract that summarized the army's grudges against Wallenstein.

Wallenstein's letters refuting the accusations against him remained unanswered, after realizing that the emperor was positioning troops in such a manner as to surround him he decided to flee to the Swedes.

At 6.00 p.m., Wallenstein's inner circle consisting of Ilow, Adam Erdmann Trčka von Lípa, Vilém Kinský and Captain Niemann were invited by the conspirators to the city's castle for a formal dinner.

Ilow grabbed his sword and charged at Gordon; before being able to strike he was knocked to the ground by the dragoons and killed, others met a similar fate.

Wallenstein was killed in his residence at 10.00 p.m. An imperial decree equated the participants of the perpetrators of the so-called Eger Bloodbath[6] with official executioners.
