Arthashastra
ततस् तद् व्यञ्जनाः प्रमत्त वधम् अवस्कन्द प्रतिग्रहम् अभिप्रहरणं पृष्ठतः शङ्ख दुन्दुभि शब्देन वा "प्रविष्टम्" इत्य् आवेदयेयुः ॥
Then spies, disguised as priests, may announce to the enemy, blowing their conch shells and beating their drums, that a besieging army, eager to destroy all, and armed with weapons, is coming closely behind them.
