Arthashastra
स्व बल रक्षा चतुर् अङ्ग बल प्रतिषेधः संग्रामे ग्रहणं मोक्षणं भिन्न संधानम् अभिन्न भेदनं त्रासनम् औदार्यं भीम घोषश् च इति रथ कर्माणि ॥
Protection of the army; repelling the attack made by all the four constituents of the enemy's army; seizing and abandoning (positions) during the time of battle; gathering a dispersed army; breaking the compact array of the enemy's army; frightening it; magnificence; and fearful noise--these constitute the work of chariots.
