In 1621, he participated in a campaign against the Hungarian rebels and took over command during the critical periodafter the death of the commander Bucquoy.

Maximilian was forced to retreat to Pozsony. In 1622 he fought in the Silesia and captured the fortress of Kłodzko, which had been in the hands of insurgents since 1618. The Emperor rewarded him for his services with confiscated possessions of Charles of Kaunitz, plus a gift of, settling the imperial debt to Maximilian for providing troops.
