British Army of the Rhine

There have been two formations named British Army of the Rhine (BAOR). Both were originally occupation forces in Germany, one after the First World War, and the other after the Second World War.

1919–1929
The first BAOR was set up in March 1919 to implement the occupation of the Rhineland It was originally composed of five corps, composed of two divisions each, plus a cavalry division:

II Corps: Commanded by Sir Claud Jacob
 * Light Division (formed from 2nd Division): Commanded by Major-General George Jeffreys
 * Southern Division (formed from 29th Division): Commanded by Major-General William Heneker

IV Corps: Commanded by Sir Alexander Godley
 * Lowland Division (formed from 9th Division)
 * Highland Division (formed from 62nd Division)

VI Corps: Commanded by Sir Aylmer Haldane
 * Northern Division (formed from 3rd Division)
 * London Division (formed from 41st Division)

IX Corps: Commanded by Sir Walter Braithwaite and later by Ivor Maxse
 * Western Division (formed from 1st Division)
 * Midland Division (formed from 6th Division)

X Corps: Commanded by Sir Thomas Morland
 * Lancashire Division (formed from 32nd Division)
 * Eastern Division (formed from 34th Division)

Cavalry Division (formed from 1st Cavalry Division)

However most of these units were progressively dissolved, so that by February 1920 there were only regular battalions:
 * 1st Battalion Royal Irish Regiment
 * 4th Battalion Worcestershire Regiment
 * 2nd Battalion Black Watch
 * 1st Battalion Middlesex Regiment
 * 3rd Battalion Middlesex Regiment
 * 1st Battalion Durham Light Infantry

In August 1920 Winston Churchill told the British Parliament that the BAOR consisted of approximately 13,360, consisting of, Staff, Cavalry, Royal Artillery, Royal Engineers, Infantry, Machine Gun Corps, Tanks, and the usual ancillary services. The troops are located principally in the vicinity of Cologne at an approximate cost per month is £300,000.

Other information
The Cologne Post was a newspaper published for members of the BAOR during this period.

1945–1994
The second British Army on the Rhine was formed on 25 August 1945 from 21st Army Group. Its original function was to control the corps districts which were running the military government of the British zone of occupied Germany. After the assumption of government by civilians, it became the command formation for the troops in Germany only, rather than being responsible for administration as well.

As the potential threat of Soviet invasion across the North German Plain into West Germany increased, BAOR became more responsible for the defence of West Germany than its occupation. It became the primary formation controlling the British contribution to NATO after the formation of the alliance in 1949. Its primary combat formation was British I Corps. From 1952 the commander-in-chief of the BAOR was also the commander of NATO's Northern Army Group (NORTHAG) in the event of a general war with the Soviet Union and the Warsaw Pact. The BAOR was formerly armed with tactical nuclear weapons.

The 1993 Options for Change defence cuts resulted in BAOR being replaced by the 25,000 strong British Forces Germany (BFG) in 1994.
