I see no reason to induce that discontent was not general in the Saxon army since:

- the very saxon guards who got Blücher satisfaction mutinied and tried to storm his headquarter, he had to be taken out
- even after execution of leaders, two other batalions mutinied
- Blücher was so unsure of the whole saxon units that he proposed them to Wellington (who declined) and had them marching home. You don't deprive yourself lightly of 14,000 men days before a difficult campaign.
