Columbus crossed the Atlantic Ocean and discovered several islands, as he believed, located somewhere off the coast. Which shores?

During the Middle Ages, overland routes to India became dangerous to trade as the frequencies were attacked by robbers. And in Europe, the idea appeared that since the earth is round, if you sail to the west, you can go around the globe and swim to India and China. Christopher Columbus on 3 ships in 1492 went in search of India, but discovered a new continent, America. Columbus then did not know about his discovery, and thought that he was in India and named the islands, which he moored in the Caribbean Sea, West Indies.
