Post-captain or post captain is an obsolete alternative form of the rank of
captain in the
Royal Navy. The term "post-captain" was descriptive only; it was never used as a title in the form "Post-Captain John Smith".
The term served to distinguish those who were captains by rank from:
* Officers in command of a naval vessel, who were (and still are) addressed as captain regardless of rank;
*
Commander
Commander (commonly abbreviated as Cmdr.) is a common naval officer rank as well as a job title in many army, armies. Commander is also used as a rank or title in other formal organizations, including several police forces. In several countri ...
s, who received the title of captain as a courtesy, whether they currently had a command or not (e.g. the fictional Captain Jack Aubrey in ''
Master and Commander'' or the fictional Captain
Horatio Hornblower in ''
Hornblower and the Hotspur''). This custom is now defunct.
In the Royal Navy of the 18th and 19th centuries, an officer might be promoted from commander to captain, but not have a command. Until the officer obtained a command, he was "on the beach" and on
half-pay. An officer "took post" or was "made post" when he was first commissioned to command a vessel. Usually this was a
rated vessel – that is, a ship too important to be commanded by a, lower-ranked, commander – but was occasionally an unrated one. Once a captain was given a command, his name was "posted" in ''
The London Gazette''.
Being "made post" is portrayed as the most crucial event in an officer's career in both Forester's
Horatio Hornblower series and O'Brian's
Aubrey-Maturin series. Once an officer was promoted to post-captain, further promotion was strictly by seniority; if he could avoid death or disgrace, he could eventually become an
admiral (even if only a
yellow admiral).
A junior post-captain would usually command a
frigate or a comparable ship, while more senior post-captains would command larger ships. An exception to this rule was that a very junior post-captain could be posted to command an admiral's flagship, which was almost always a large
ship of the line. The admiral would usually do this to keep his most junior captain under close observation and subject to his direct supervision. Captains commanding an admiral's flagship were called "
flag captains". One example of this is the appointment of
Alexander Hood to the command of
HMS ''Barfleur'', flagship of his cousin, Admiral
Sir Samuel Hood.
Sometimes a high-ranking admiral would have two post-captains on his flagship. The junior would serve as the
flag captain, listed in the ship's roll as the "second captain", with responsibility for the day-to-day operation of the vessel. The senior would be the
captain of the fleet, listed as "first captain", and serving as the admiral's chief-of-staff.
After 1795, when they were first introduced on Royal Navy uniforms, the number and position of
epaulettes distinguished between commanders and post-captains of various seniorities. A commander wore a single epaulette on the left shoulder. A post-captain with less than three years' seniority wore a single epaulette on the right shoulder and a post-captain with three or more years seniority wore an epaulette on each shoulder. In the O'Brian series, Aubrey "wets the swab" – that is, he celebrates his promotion to commander and the acquisition of his "swab" or epaulette with the consumption of copious amounts of alcohol.
