Post-Captain

Post-Captain is an obsolete alternative form of the rank of Captain in the Royal Navy.

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;
• commanders, 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); this custom is now defunct.

Once an officer had been promoted to post-captain, his further promotion was strictly by seniority; if he could avoid death or disgrace, he would eventually become an admiral (even if only a yellow admiral).

In the Royal Navy of the time, an officer might have a rank, but not a command. Until the officer had a command, he was "on the beach" and on half-pay. An officer who was promoted from commander was a captain, but until he was given a command, he was on half-pay. Once the captain was given a command, his name was "posted" in the "Naval Gazette."^{[citation needed]}

An officer "took post" or was "made post" when he was first commissioned to command a rated vessel — that is, a ship too important to be commanded by a mere commander. Unrated vessels could also in some cases be commanded by post-captains. 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.

A junior post-captain would usually command a frigate or a comparable ship, while more senior post-captains would command larger ships.

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. (National Maritime Museum Uniform Collection, see below.) 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.

Note that the term was descriptive only: no-one was ever styled "Post-Captain John Smith".
