Alexander's decision to let so many of his men go could be attributed to the fact that he could afford to let them go.
And besides technically he was only relieving them, not really losing them.
And it was a point Heliptos was the first one to chime,
"The lord is right. As long as the officers and instructors are there, our army will still be strong." "Besides, we are not really losing those men. They still exist. We can call them back anytime."
"When we organize long campaigns, our armies will certainly be bolstered by levies and they can join then, as temporary officers or regular infantry."
"I think it's not a bad idea."
Heliptos pointing this fact out made the others quickly take note of it.
He was right.
The veteran soldiers were still with them, just working as peasants or merchants or being retirees.
So Melodias then next said, "Also, they can help defend the city if something happens while we are away."
