Grenville and the "Tiger" waited in Puerto Rico for the other ships. While they were waiting, Grenville built a fort called Fort Elizabeth. He also did some privateering from there against the Spanish. One of the other ships, the "Elizbeth", arrived in Puerto Rico right after Fort Elizabeth was built. Grenville soon got tired of waiting for the other ships. On 7 June 1585 he left Puerto Rico and abandoned the fort. Nobody knows what happened to the fort, or where exactly it was.
