In 47 BC, during the Roman Civil War, Julius Caesar's army begged to fight for him.
Although the war was still on in North Africa, his Italian units (30,000 men) mutinied because he hadn't paid them their wages.
They threatened to destroy Rome if they weren't paid immediately.

As the mutinous army destroyed the land, Caesar arrived the scene.
The soldiers were very angry, but he walked up to them and addressed them as "Citizens".
They were shocked. He promised he would pay all he owed them, but they would no longer be his soldiers.

Since there was no money, he would first have to search for braver men and sail to Africa, where he would destroy his enemies and take all their lands and wealth.
After that, he would treat his new soldiers like kings and war heroes, and give them befitting treasures.

His old army (the mutinous soldiers) would be paid their wages as civilians, with no glory.
He turned to leave, and the soldiers started crying and begging him not to go to Africa without them.
They promised not to bother him for money again, they promised to be good boys.

Caesar could have used another army to disrupt the rebellion. Or used intimidation.
All he said was:
"You're not my soldiers anymore. I don't need you. You are average Roman citizens now."
And they begged him to need them. He acted like he didn't care, but finally agreed.
