To them, their general's orders were over any other order, as it was their general that had always led them to victory even when their chances were slim, or non-existent.
So, their loyalty didn't lie with the tribe, or their tribe head but with their general. Most probably if their general told them to fight the tribe Head, and their tribe they would do so as well.
There existed such generals too, people who could make their warriors fight for them until the last of their breath, and even sacrifice their selves for their general.
Such a general, and such warriors were rare but weren't non-existent. As their relationship had developed through sweat and blood. It was a brotherhood that surpassed the normal one.
Just looking at this situation, as these warriors immediately changed their direction like hungry beasts with just one order from their general was enough.
