The king was the chief commander of the army and usually led his army in the battlefield. The military was said to be fourfold : the infantry, the cavalry, the elephantry and the chariotry. A wide variety of war weapons filled the military arsenal including shields, swords, spears, tridents, maces, bows and arrows. A successful war could lead to annexation of territories or the submission of the enemy, who would then recognize the hegemony of the victor and start paying tributes.
