No, really, guys, STOP BLAMING TILLY.
Yeah, he provided The German Catholic League with an amazing army. But you may say he is responsible for defeat at Breitenfeld. That's nonsense: Pappenheim is responsible for that defear. He started the battle. He exhausted the Imperial army by attacking enemy pikemen SEVEN TIMES. SEVEN DAMNED TIMES. Of course, his cavalry retreated in disorder. It resulted in that defeat. Thank you, Gottfried.
Well, there's still one more major fail of Tilly. Yes, I'm talking about the Magdeburgs Opfergang. Tilly and his 24.000 men besieged Magdeburg to capture his stores (Magdeburg was a VERY important, populous and rich city and had a garrison of 2.400 men led by Dietrich von Falkenberg). Falkenberg tried to reinforce the city for some time but the magistrate refused to support him. Pappenheim took five infantry regiments and tried to breach through the wall near Neustadt. Of course, he wasn't very successful and reached the glacis in 23 days (by the way, the escarpe was low and the moat was shallow there). Finally Pappenheim began the assault. Falkenberg almost supplanted Imperial forces from the wall but was shot. The city was captured, plundered and burned. It made lots of Lutheran counts of HRE to ally with Gustavus Adolphus. I don't think Tilly could destroy a foothold in the Northern Germany (especially a foothold that was a religious centre). So looks like the city was ignited by forces of Falkenberg. He knew that the garrison couldn't last long and didn't want to allow the Catholics to capture an important base.
So guys stop blaming Tilly. He was a loyal general and a good man. Even on deathbed he commanded his troops.
Good job Johann.
