Jamieson, Fausset and Brown on Titus 3:12

12. When I shall send--have sent.

Artemas or Tychicus--to supply thy place in Crete. Artemas is said to have been subsequently bishop of Lystra. Tychicus was sent twice by Paul from Rome to Lesser Asia in his first imprisonment (which shows how well qualified he was to become Titus' successor in Crete); Ep 6:21; and in his second, 2Ti 4:12. Tradition makes him subsequently bishop of Chalcedon, in Bithynia.

Nicopolis--"the city of victory," called so from the battle of Actium, in Epirus. This Epistle was probably written from Corinth in the autumn. Paul purposed a journey through Ætolia and Acarnania, into Epirus, and there "to winter." See my Introduction to the Pastoral Epistles.
