Why did Paul go to Troas?
Paul went to Troas because he hoped to meet Titus there. Titus had been ministering in Corinth, and Troas was the ancient city of Troy where Paul expected to connect with him. This occurred during Paul's second missionary journey, after he had left Ephesus.
Les explains that Paul went up to Troas, the ancient city of Troy, because he had hoped to meet Titus there. Titus had been down ministering at Corinth. Earlier, Paul had left Ephesus, where he faced intense opposition from the pagan population devoted to Diana. Les notes this was Paul's second missionary journey, as the churches were founded on his first missionary journey.
