The Battle of the Delta was a sea battle between Egypt and the Sea Peoples, circa 1175 BCE when the Egyptian pharaoh Ramesses III repulsed a major sea invasion. The conflict occurred somewhere at the shores of the eastern Nile Delta and partly on the borders of the Egyptian Empire in Syria, although their precise locations are unknown. This major conflict is recorded on the temple walls of the mortuary temple of pharaoh Ramesses III at Medinet Habu.
