Arthashastra
शून्य मूल अस्वामि संहतयोः शून्य मूलं कृत पौर जानपद आरक्षं सर्व संदोहेन युध्येत, न अस्वामि संहतं राज सेना पति हीनम् ॥
Of armies without communication or without leaders, that which has lost its communication with the base of operations may be taken to fight after restoring the communication and placing it under the protection of citizens and country people, but not the army which is without a leader such as the king or any other persons.
