In the Mahabharata war, Yudhisthira famously announced 'Ashwatthama hatha' (Ashwatthama is dead), which was a half-truth used to deceive Drona. While an elephant named Ashwatthama had been killed, Drona's son Ashwatthama was still alive. Drona, demoralized by this news, lowered his weapons and was killed.
