Definition of 'Post-captain'
From: GCIDE
- Post-captain \Post"-cap`tain\, n. A captain of a war vessel whose name appeared, or was "posted," in the seniority list of the British navy, as distinguished from a commander whose name was not so posted. The term was also used in the United States navy; but no such commission as post-captain was ever recognized in either service, and the term has fallen into disuse. [1913 Webster]
