Overview
The Battle of Kadesh took place between the Egyptian Empire and the Hittite Empire in the 13th century BC, with the former led by Ramesses II and the latter led by Muwatalli II. Both sides engaged each other at the Orontes River, just upstream of Lake Homs and near the archaeological site of Kadesh, along what is today the Lebanon–Syria border.
It is generally dated to May 1274 BC, as accounted by Egyptian chronology, and is the earliest pitched battle in recorded history for which details of tactics and formations are known. It is believed to have been the largest chariot-involved battle ever fought, involving between 5,000 and 6,000 chariots in total.
In the critical moment of the battle, Ramesses and his body guard were surrounded, and he broke out by personally leading several charges into the Hittite ranks.
Background
After expelling the Hyksos' 15th Dynasty around 1550 BC, the Egyptian New Kingdom rulers became more aggressive in reclaiming control of their state's borders. Thutmose I, Thutmose III and his son and coregent Amenhotep II fought battles from Megiddo north to the Orontes River, including conflict with Kadesh.
