On September 15, 1539, Hernando de Soto and his army arrived at the village of Napituca, where chiefs demanded the release of the captive Chief Aguacalequen. According to Juan Ortiz's later account, Chief Napituca secretly revealed to Indian interpreters that he planned to ambush the Spaniards and kill de Soto, and the interpreters warned Ortiz. At another meeting outside the village that morning, more than 400 Indian warriors waited in the surrounding woods ready to attack. When Napituca gave the signal, the Spaniards were prepared, their trumpeter sounded a charge, and they struck first. One hundred of Napituca's warriors were killed, and the rest were captured for use as slaves. Rodrigo Rangel recounted that, before the trumpet could sound, Luis de Moscoso urged the mounted men forward, and the horsemen lanced many Indians, while the Indians still defended themselves fiercely. The captives did not submit quietly: one warrior broke free from his guards and attacked de Soto, breaking his nose, which prompted a revolt in which several warriors seized Spanish weapons and attacked. They were quickly subdued, shackled with neck and leg irons, and those who had actively participated were ordered executed by de Soto's Indian allies. The Spanish often chained Indian captives to prevent escape while traveling through their own tribal lands, then unchained them in neighboring chiefdoms, where most remained with their captors rather than face tribal enemies alone and unarmed.
