17th century BCE (Hattusili I). A Hittite horse-training text is attributed to Kikkuli the Mitanni (15th century BCE). The Hittites were renowned charioteers. They developed a new chariot design that had lighter wheels, with four spokes rather than eight, and that held three rather than two warriors. It could hold three warriors because the wheel was placed in the middle of the chariot and not at the back as in Egyptian chariots. Typically one Hittite warrior steered the chariot while the second man was usually the main archer; the third warrior would either wield a spear or sword when charging at enemies or hold up a large shield to protect himself and the others from enemy arrows. Hittite prosperity largely depended on their control of trade routes and natural resources, specifically metals. As the Hittites gained dominion over Mesopotamia, tensions flared among the neighboring Assyrians, Hurrians, and Egyptians. Under Suppiluliuma I, the Hittites conquered Kadesh and, eventually, the whole of Syria. The Battle of Kadesh in 1274 BCE is likely to have been the largest chariot battle ever fought, involving over 5,000 chariots. Bronze Age India Models of single axeled, solid wheeled, ox drawn vehicles, have been found at several mature Indus Valley cites, such as Chanhudaro, Daimabad, Harappa, and Nausharo, and are depicted in second millennium BCE Chalcolithic rock art, of the region. Spoked wheeled, horse drawn, chariots, often barring an armed passenger, are depicted, in second millennium BCE, Chalcolithic period rock paintings.. Examples are know from Chibbar Nulla, Chhatur Bhoj Nath Nulla, and Kathotia. There are some depictions of chariots among the petroglyphs in the sandstone of the Vindhya range. Two depictions of chariots are found in Morhana Pahar, Mirzapur district. One depicts a biga and the head of the driver. The second depicts a quadriga, with six-spoked wheels, and a driver standing up in a large chariot box. This chariot is being attacked. One figure, who is armed with a shield and a mace, stands in the chariot's path; another figure, who is armed with bow and arrow, threatens the right flank. It has been suggested (speculated) that the drawings record a story, most probably dating to the early centuries BCE, from some center in the area of the Ganges–Yamuna plain into the territory of still Neolithic hunting tribes. The very realistic chariots carved into the Sanchi stupas are dated to roughly the 1st century. Bronze Age
