In November 1629 he became so ill that he lay down for weeks. In March 1630 he traveled to Karlovy Vary (Karlsbad) to seek relief. He found it difficult to walk. At the Battle of Lützen in November 1632, he mounted his horse in extreme pain. Half a year later he was no longer able to ride. On his flight to Eger in 1634 he had to be moved around in a wagon or lying in a transport litter.
