He is one of the top military official

Young Ponce de Leon would have served Guzmán's needs as a squire by tending to his horse's needs, assisting him with his clothing, and performing other tasks. He would be given instruction in social graces, hunting, and rigorous military training in exchange. In order to battle the Muslim Moors in the Kingdom of Granada in 1487, he had to put his military prowess to the test. In 1492, the conflict was over.

One of the achievements of Juan Ponce de Leon, you probably didn't know that early in the 1500s, Ponce de Leon held a senior military position in the Hispaniolan colonial government, when he assisted in putting down a Tano insurrection. He was given permission to visit the adjacent island of Puerto Rico in 1508 and was appointed by the Spanish king to serve as the country's first governor in 1509. While Ponce de León amassed considerable fortune from his plantations and mines, he was engaged in a court dispute over control of Puerto Rico with Diego Colón, the late Christopher Columbus's son. In 1511, Columbus succeeded Ponce de León as governor following a protracted legal dispute. Ponce de Leon made the decision to take the sympathetic King Ferdinand's advise and continue his exploration of the Caribbean Sea.
