 Convoys codes during the Battle of the Atlantic ( July 1940 )
BB - Belfast to Bristol Channel (The BB series of convoy ran from Belfast Lough to Milford Haven.)

BHX - Bermuda Joiner to HX (The BHX series carried traffic from Bermuda to join the HX convoy of the same number at sea which was sailing from Halifax to the UK.)

EC - Southend to Oban via Firth of Forth (The EC series sailed from Southampton to the Clyde.)

EN - Methil to Oban via Loch Ewe (The EN series ran from Methil, on the east coast of Scotland, to Oban (later Loch Ewe) on the west coast.)

FS - Forth South, Firth of Forth to Thames (The FS series of convoy ran from Methil or the Tyne (mainly Nov. 1939 - Aug. 1940) to the Thames (Southend).)

FN - Forth North, Thames to Firth of Forth (The FN series of convoy ran from the Thames (Southend) to the Firth of Forth (Methil).)

HN - Norway to United Kingdom (The HN series sailed from Norwegian waters to Methil from October 1939 to April 1940 when it ceased due to the occupation of Norway.)

HX - Halifax to United Kingdom (From September 1939 until September 1942, the HX series carried traffic from Halifax, Nova Scotia, to Liverpool. Subsequent to September 1942, and until the end of the war, this series departed from New York. Slower vessels were routed in the SC series while faster vessels sailed in the short lived HXF series. Additionally, the BHX series sailed from Bermuda and rendezvoused with the HX convoy of the same number. )

KS - Hampton Roads - Key West (The first KS series sailed from Casablanca mainly to various French ports until June 1940. The second series started at KS.500 sailing from Hampton Roads to Key West between May and September 1942.

OB - Liverpool outward (The OB series of convoy sailed from Liverpool and catered for vessels sailing transatlantic to North and South America; for the South Atlantic to Freetown, the Cape and beyond together with coastal traffic. En route, vessels sailing from the Bristol Channel ports (Avonmouth, Barry, Newport and Cardiff) would join the convoy at a designated position, usually a few miles south of the Smalls Lighthouse (51.43N, 5.40W). The OB series ran from September 7, 1939 (OB.1) to July 21, 1941 (OB.349) when two new convoy series were formed. The OS series to Freetown, Sierra Leone, for ships bound for the South Atlantic (later sailing with the KMS series to Gibraltar) and the ON series sailing west to Halifax although initially these were still dispersed before reaching their destination. The OA series ceased on October 24, 1940 (OA.234).

ON - Liverpool to New York Fast (The ON series of mercantile convoy replaced the OB series in July 1941 and continued until May 1945. Initially it sailed from Liverpool and was dispersed about 750 nautical miles west of Lands End as the OB convoys were. Later, as escorts became available (March 1942), it was escorted all the way to ports in Canada or the USA. From October 1944 sailings also started from Southend with the Liverpool section joining at sea.)

OS - Liverpool Freetown (Outward Southbound, Liverpool etc. to Freetown 1941 onwards.)

SC - Halifax Slow to United Kingdom (The SC series of convoy sailed from Sydney CB (later Halifax or New York, depending on the season) to the UK and accomodated older and slower vessels. The series ran from August 1940 until May 1945.)

SL - Freetown - Liverpool (The SL series of convoy catered for vessels returning to the UK from the South Atlantic commencing from the collection point of Freetown in Sierra Leone. The first SL convoy was in September 1939 and some forty SL convoys had been escorted before the complementary OS series (UK - Freetown) began in July 1941. Initially, the series alternated between fast (SLF) and slow (SL) convoys and from January 1940 (SL.15) the fast convoys would rendezvous with the preceding slow convoy, somewhere within European waters, in order to economise on escort vessels. This practice was in force intermittently until January 1941 (SL.65) when the fast and slow sections were combined. Initially, the fast convoy was designated SLF (SL being SLOW) and later the slow convoy was designated SLS (SL being FAST).)

WN - Clyde, Oban & Loch Ewe to Firth of Forth (The WN series of coastal convoy carried local traffic from the Clyde to Methil on the Firth of Forth. The series ran from July 1940 until the end of the war.)
