Arthashastra
"प्रभूतं मे भृत बलम् अल्पं च मौल बलम्ण्" "परस्य अल्पं विरक्तं वा मौल बलम्, फल्गु प्रायम् असारं वा भृत सैन्यम्ण्" "मन्त्रेण योद्धव्यम् अल्प व्यायामेनण्" "ह्रस्वो देशः कालो वा तनु क्षय व्ययह्ण्" "अल्प आवापं शान्त उपजापं विश्वस्तं वा मे सैन्यम्ण्" "परस्य अल्पः प्रसारो हन्तव्यह्ण्" इति भृत बल कालः ॥
When he thinks that the army he has hired is greater than his hereditary army; that his enemy's hereditary army is small and disaffected, while the army his enemy has hired is insignificant and weak; that actual fight is less than treacherous fight; that the place to be traversed and the time required do not entail much loss; that his own army is little given to stupor, is beyond the fear of intrigue, and is reliable; or that little is the enemy's power which he has to put down, then is the time for leading the hired army.
