Kautilya's Arthashastra 7.5.43

7.5.43

samenaikena dvābhyāṃ hīnābhyāṃ veti dvābhyāṃ hīnābhyāṃ śreyaḥ //

Combined with one of equal power or with two of lesser power, should a king march against his enemy?

Better to march with two kings of lesser power; for the conqueror can depute them to carry out any two different works and keep them under his control. When the desired end is achieved, the inferior king will quietly retire after the satisfaction of his superior.
