JACK

A flag, originally (and sometimes still) much smaller than the ensign, flown from a staff at the bow of a ship, usually when that ship is berthed, at anchor or moored to a buoy, occasionally when underway but always when dressed overall, and which in current usage may fall into one of the three main categories listed below – a bow flag (see also ‘colonial jack’, ‘distinguishing jack’, ‘dress ship’, ‘jack of honour’, ‘jack staff’, ‘privateer jack’ and ‘union jack’) ^{See supplemental note}:

Civil Jack

Flown at the bow of a merchant ship (see also ‘civil ensign’ under ‘ensign’).

Civil Jack of the Bahamas (fotw); Civil Jacks of The Netherlands - unofficial (fotw & Peter Hans van den Muijzenberg)

Please note, however, there are only two countries who prescribe a distinctive jack for general use by civilian vessels – the UK (see ‘pilot jack’) and the Bahamas as illustrated above. Sweden, for example, specifies regional flags, whilst the flags of home ports are sometimes officially used and the regulations of some shipping lines call for a house or other flag with this, upon occasion, being expressly permitted under national legislation.

Government Service Jack

Generally, but not exclusively, limited to the UK and former British colonies, and flown at the bow by civilian-manned Government vessels – but see ‘colonial jack 1)’ with its following note (also ‘government ensign’ under ‘ensign’ and the notes below).

Jacks of The Royal Fleet Auxiliary (Martin Grieve), The Royal Maritime Auxiliary (Martin Grieve) and Northern Lighthouse Board, UK (fotw)

Notes
a) In UK usage all Government service vessels wearing defaced blue ensigns, including those used by the governing authorities of dependent territories, are legally entitled to fly a blue jack with an appropriate badge in the fly, however, (as far as can be discovered) only the Royal Fleet Auxiliary, the Royal Maritime Auxiliary and the Northern Lighthouse Board actually do so at present.
b) In Germany and Austria, Government (as well as civilian) vessels often fly the flag of the relevant state/province, and that in some commonwealth countries the appropriate departmental flag is specified as a jack for government vessels.

Naval Jack

Flown at the bow of a warship, often the appropriate national flag (or a variation of it), occasionally the same as the naval ensign, or sometimes a completely different design - the jack (see also ‘masthead pennant 1)’, ‘naval ensign’ under ‘ensign’, ‘jack staff’ and ‘suit of flags’).

Naval Jacks of Russia (fotw); Brazil (fotw); Norway (fotw); Italy (fotw) and The Netherlands (fotw)

JACK OF HONOUR (or HONOR)

In French naval usage, a jack originally flown in place of le tricolore by ships that had served in the Free French Navy (the FNFL), and now flown by those ships bearing the same name (see also ‘cravat 1)’ and its following note, ‘fanion 3)’, ‘jack’, ‘lanyard 1)’, ‘lanyard pennant’ and ‘tricolour 3)’).

JACK, THE

JAGIELLONIAN

In East European usage a term often used to describe historic or traditional symbols, and taken from the dynasty which ruled Poland, Lithuania, Hungary, and Bohemia from the 14th century until the 16th century – for example the Jagiellonian cross or Jagiellonian eagle.

JAMES UNION

An unofficial name for the 1606 pattern British union flag (see also ‘British flag’, ‘His Majesty's jack’, ‘interlaced’ ‘conjoined’ and ‘union jack’).

Union Flag 1601 – 1801, England/UK (fotw)

Please note that this term appears to have been a 19th Century invention, and that there is no firm evidence of it being used during flag’s lifetime (1606 – 1801).

JEHOVAH SUN

The term – and a direct translation of the German Jehovasonne – which may be used to describe a sun in splendour, surmounted by a cartouche bearing the name of God in Hebrew lettering - a charge sometimes to be seen on (exclusively Protestant) German military flags of the 16th and 17th Centuries (see also ‘cartouche’, ‘sun-in-splendour’ and ‘surmounted by’).

JOLLY ROGER

1) Generically, any black (or occasionally red) flag often (but not invariably) bearing white symbols and associated with piracy, but usually shown in its modern form as a flag with black field and stylised white skull above two white crossed bones - a skull and cross-bones (see also ‘privateer ensign’).

2) A flag of the latter description given above, but defaced by a number of varying symbols dependent upon the type of action and used unofficially by the submarine service of the British Royal Navy and some others to signify that the boat flying it had successfully engaged an enemy – but see ‘battle flag 3)’ (also ‘deface’).

Flag as described above (fotw); Flag of Bartholomew Roberts 17th C (fotw); Flag of Edward Lowe Early 18th C (fotw); Submarine Service, UK (fotw).

Notes
a) With regard to 1), vessels of the US Navy often fly a Jolly Roger at the yardarm during line-crossing ceremonies (as the signal that King Neptune is aboard), and note also that of all known pirates only Blackbeard is thought to have actually used this design. (see also ‘yardarm’).
b) With regard to 2), it should be emphasised that these symbols were (and are) entirely unofficial, and that a several variations are known.
