Battle of Kadesh

Ramesses II marched north to fight the Hittites at Kadesh (modern Syria) and almost got ambushed when Hittite spies fed him fake intel. The battle was basically a draw but Ramesses went home and carved propaganda everywhere saying he won single-handedly. The real W came later — the Egyptian-Hittite peace treaty is the oldest surviving international peace agreement. A copy hangs in the UN headquarters.
