But the worst was yet to come. The Aztecs, now under the new huey tlatoani Cuitláhuac, massed a huge army on the plain of Otumba to finish the invaders for good. This episode reconstructs the desperate Battle of Otumba — July 7, 1520 — where a ragtag force of 400 Spaniards, 4,000 Tlaxcalan allies, and one great war horse named El Morcillo faced perhaps 40,000 Aztec warriors. We trace Cortés's tactical gamble, the critical role of Tlaxcalan infantry, and the moment a young cavalryman named Juan de Salamanca allegedly killed the Aztec commander Cihuacoatl Matlatzincatzin, shattering the Aztec will. We also explore the Otumba battlefield archaeology, the debate over casualty numbers, and what this pyrrhic victory meant for the eventual fall of Tenochtitlan. A turning point where the conquest nearly ended — but didn't. #BattleOfOtumba #Cortés #Cuitláhuac #Tlaxcala #JuanDeSalamanca #ElMorcillo #AztecEmpire #LaNocheTriste #Conquistadors #MesoamericanHistory #WarHorses #16thCentury #IndigenousAllies #Mexica #Otumba #MilitaryHistory #History #FexingoHistory Keep every episode free: buymeacoffee.com/fexingo ## Actions - request_transcript: `POST https://stenobird.com/v1/public/podcasts/the-conquistadors-exploration-greed-and-destruction-fexingo-history-7864470/episodes/the-battle-of-otumba-aztec-fury-after-la-noche-triste/transcription-requests` — Idempotently request low-priority transcript generation for this episode. - read_markdown: `GET https://stenobird.com/podcast/the-conquistadors-exploration-greed-and-destruction-fexingo-history-7864470/the-battle-of-otumba-aztec-fury-after-la-noche-triste.md` — Read the agent-friendly Markdown representation of this episode resource.
