Arthashastra
अमित्रस्य वा बल काले प्रत्युत्पन्ने शत्रु बलम् अवगृह्णीयात्, अन्यत्र वा प्रेषयेत्, अफलं वा कुर्यात्, विक्षिप्तं वा वासयेत्, काले वा अतिक्रान्ते विसृजेत् ॥
When the time for the march of one's enemy's army has approached, one has to obstruct the enemy or send him far away, or make his movements fruitless, or, by false promise, cause him to delay the march, and then deceive him after the time for his march has passed away.
english translation
