You unsheathe your sword, hop on your horse and CHAAAARRRRGGEE!!

Either due to your reputation, the 'purge' a while ago or mayhaps inner courage of your men, your soldiers run after you and rush the enemies, smashing their battle lines! Mercenaries and peasants soon flee on en masse, abandoning their equipments and their masters to preserve their lives instead. Enemy numbers thin considerably!

The battle then descends into a slaughter of the rebel officers, noble sons and their lackeys who too late notice they've picked wrong side of the conflict.
As the moon peeks over the horizon, one of soldiers with haste presents you a gruesome trophy; the bloodied and severed head of Daeh Cuthwynn, its identity confirmed by the few captives that survived the battle. The deed of the soldier youth is attested by comrades from his unit and therefore you bestow him a knightly rank. He kisses your royal signet in gratitude.
Next morning, as dead are buried and wounded carried away, your Army returns home as scouts report no one else is nearby to rise against you.
Few days later you return to the palace. The Marshal and the Spymaster begin investigation into sudden riot in the Army.
1130 AD, Mid-Autumn
You set the goblet down and nod at the Spymaster, who opens up his scroll.
"Your Majesty, the riot has been sparked by one of well-liked junior officers. A recent Enyntheist convertee and believer in superiority of the Army, he took your order of withdrawal as a sign of cowardice, apprently well-suited a scandalous King like you."
"Scandalous?"
"Sire, you married the heir to the throne of Methiant to a commoner. You allowed his twin brother to die and did nothing to avenge him. And then there's recent religious upheaveal in the country. It's impossible to not have some younger soldiers influenced by all this." Maybe indeed it is time to loosen up on your peoples? Or is it time for purges in the Army?
As for the people's mood...
A) Give extra pay to all soldiers' and officers' families.
B) We can deal with happiness of my people later.
As for the Army purges...
A) We don't need any.
B) Purge religious zealots from my Army!
C) Shake the top levels of hierarchy a bit!
