How did Cortes ensure his soldiers did not mutiny and return to Cuba?

Cortes ensured his soldiers did not mutiny or return to Cuba by taking decisive actions upon their arrival in Mexico. He famously scuttled his ships, eliminating the option of retreat and forcing his men to commit fully to their mission. Additionally, he fostered a sense of loyalty and camaraderie among his troops by sharing in their hardships and promising them wealth and glory from the conquests ahead. This combination of eliminating escape routes and motivating his soldiers helped maintain their focus on the campaign.
