The wealth of Tenochtitlan was astounding, and Cortes and his lieutenants began plotting how to take the city. Most of their plans involved capturing Montezuma and holding him until more reinforcements could arrive to secure the city. On November 14, 1519, they got the excuse they needed. A Spanish garrison left on the coast had been attacked by some representatives of the Mexica and several of them were killed. Cortes arranged a meeting with Montezuma, accused him of planning the attack, and took him into custody. Amazingly, Montezuma agreed, provided he be able to tell the story that he had voluntarily accompanied the Spanish back to the palace where they were lodged.
