Preparing for British Resistance in WW2
A range of secret organisations were created that each had their own particular task following invasion. None of these was named by contemporaries as the 'British Resistance Organisation'. The latter is a modern, and misdirected, convenience that has distorted an objective history of the subject and which now survives only through an emotional reluctance to discard the trope.
These bodies had no unified structure, partly from reasons of security but also due to inter-departmental rivalry between the War Office and the Secret Intelligence Service (SIS, aka MI6). The latter had also established a policy that there should be overlays of intelligence networks, with one organisation responsible for short term sabotage and a second organisation - kept separate and secret - that would plays no part in the invasion phase but would prepare for long term resistance following any occupation. This was a principle that was maintained into NATO's planning to counter any Soviet invasion of Western Europe during the Cold War.
Information on many aspects remains speculative. In many cases the volunteers were never told for whom they worked and some tasks may have been allocated on a purely individual basis.
In recent years, the operational patrols of the Auxiliary Units of the War Office have been popularly labelled as the 'British Resistance Organisation'. This is a fundamental misunderstanding of their role and has created a modern myth. Fact and fiction has merged. The War Office were not in the business of creating resistance organisations and for some generals, the whole concept smacked of defeatism. Instead, the War office focussed on the immediate aim of defeating a Nazi invasion.
By contrast, the brief of SIS was to plan for operations after any long-term occupation of the country and they argued for a layered system, designed to conceal the existence and security of a long-term resistance organisation. The operational patrols of Auxiliary Units proved to be a useful diversion from this aspect of the secret war. The Special Duties branch of the Auxiliary Units has more claim to the name 'resistance', at least in intention. But, whilst impractical in resisting any German invader, its most important function came to be monitoring the British populace and troops as pat of the security system of MI5 and Military Intelligence .
The main organisations are described below in order of their initial deployment.
SIS SECTION VII RESISTANCE
Formed around February / March 1940 in utmost secrecy even within SIS, and given cover within their accountancy branch (Section VII). Based upon SIS experience in creating a spy network in Eire. The wireless network was fully mobilised in June 1940, with probable links to the Special Communications Units of SIS. The priority was in gathering intelligence but the organisation also maintained a separate sabotage / assassination wing. Described as being fully operational by October 1940, the Section VII organisation remained active until at least 1944, during which time its intelligence wing assisted MI5 in hunting down enemy spy rings. The sabotage wing included the recruitment of Home Guard and regular army personnel who were trained in improvised weapons that could be replicated after occupation. These men were told to return to their units and keep such training secret until it was needed. Teenage volunteers were warned to hide during the actual invasion in order to avoid conscription under martial law. In the event of invasion, volunteers were instructed to only commence operations after occupation. Unlike the Auxiliary Units, this was a countrywide organisation. This was the 'real' British Resistance.
SIS cells are documented in Norfolk, Suffolk, Sussex, Isle of Wight, Somerset, Cornwall and Devon. Oral testimony includes other cells in Derbyshire, Worcester, Birmingham, Nottingham and Manchester. Some of the most intense research on the Auxiliary Units has been carried out in a number of these areas and the previous failure to identify the existence of such networks is a measure of their secrecy. It is, however, now possible to re-interpret some evidence of what was previously automatically assumed to be Auxiliary Unit activity as being that of the SIS Section VII organisation (e.g. see Freethy, Ron, Lancashire 1939 - 1945: The Secret War, Chapter 11).
SIS SECTION D HOME DEFENCE SCHEME
Launched somewhat chaotically in May 1940 by Laurence Grand, and led by Viscount Bearsted, as a knee-jerk resonse to the fall of France, but based upon a methodology derived from experience in Poland, Norway and France. The War Office feared its development as an SIS private army and this led directly to the creation of the rival Auxiliary Units. Likewise SIS HQ feared that the Section D operation was uncontrollable under Grand, and risked the security of its deep cover Section VII operation. By July, the HDS was focussing on a resistance role to activate once the new Auxiliary Units had been destroyed. The War Office finally managed to close down the HDS operational wing in August 1940, although SIS discretely transferred some of its intelligence officers to the new Auxiliary Unit organisation in order to protect its own interests. The intelligence wing of the Home Defence Scheme was transferred en bloc to the Auxiliary Units by Bearsted, and formed the basis of the Special Duties Branch of the latter, but continued to be managed by SIS until the end of 1940.
HOME GUARD INDUSTRIAL SABOTAGE UNITS
The direct role of the Home Guard in secret warfare is often overlooked. One of the duties of top secret Home Guard units working in local factories was to ensure the disabling of industrial machinery and fuel supplies. The intention was to deny the Nazis the use of such facilities but to ensure that the British could quickly put them back into service after a successful counterattack. This was especially important with regard to fuel supplies. In France, German tanks had literally filled up at local petrol pumps because no-one had given the order to destroy them. But equally, if there was to be a successful counter-attack, British vehicles would need continued access to fuel. So simply destroying fuel stocks was a poor option. To this end, small teams of Home Guard would dismantle key parts of machinery at the point that the Nazis were about to overrun an area, as well as removing blueprints etc. Only the members of the team would know the location of the hiding places. The lengths that the Gestapo would go to identify the members of such teams as the 'Pump Disrupton Squads', and their families, can only be imagined.
XII CORPS OBSERVATION UNIT
Prototype of the Auxiliary Units, formed in Kent and Sussex by General Thorne and Captain Peter Fleming of MI(R) in early June 1940, with a wireless network provided by SIS. Named after the WW1 Lovat Scouts recce teams. Some of the officers were probably trained at the Osterley Home Guard School. Based around regular army battle patrols, supported by Home Guard patrols. It could operate at a more strategic level than the Auxiliary Units, due to its direct relationship to the Corps command structure. The Auxiliary Units did not achieve this until 1942.
GHQ AUXILIARY UNITS
The role of the operational patrols of GHQ Auxiliary Units was as a short-term commando force to operate (in uniform) behind enemy lines in the first few days following invasion. They evolved out of the XII Corps Observation Unit as a War Office response to the SIS Home Defence Scheme. With no clear brief, it had hesitant beginnings and did not begin to properly mobilise until mid-July 1940, remaining an essentially coastal organisation. The Auxiliary Units were originally intended by Colin Gubbins to serve as an advisory body to the creation of small commando teams directly managed by the LDV (see HERE). Their main role was to be as guides to regular army commando units who would be slipped behind enemy lines. Unfortunately there were not the resources at the time to expand the existing 'Independent Companies' to provide the army commando units, and so the Auxiliary Units quickly took on a life of their own, organising their own Home Guard commando force, with a small regular army element of Scout Sections. The instructions were to operate on the flanks and to the rear of an invading army during an active military campaign, thereby extending the official harassing role of the rest of the Home Guard, but the lifespan of the teams was assumed to be not more than two weeks. They would fight in uniform and under military discipline as part of the organised military response to invasion. Longer-term civilian resistance was in the hands of SIS. The lack of wireless communications greatly limited their strategic role after the destruction of their designated primary targets. Nonetheless, the ability to delay enemy movements even by just a few hours was considered critical in the 1940 anti-invasion planning. The nature of the Auxiliary Units changed considerably from 1941 as it became more clearly absorbed by regular army structures. The Auxiliary Units survived until 1944 and the disbanding of the Home Guard, largely due to a promise that its Home Guard volunteers would not be returned to general duties.
The intelligence wing of the Auxiliary Units - the Special Duties Branch - was directly inherited from the Home Defence Scheme of SIS, who continued to manage it during 1940 when its c.1,000 agents did have some claim to an intended 'resistance' function in collecting intelligence on any German invasion. However, at the time it had no effective mechanism for passing on this intelligence and remained under-developed. The Special Duties Branch effectively remained a separate organisation and the Auxiliary Units HQ were never quite sure of its role. From 1941 it developed a wireless network based on the novel TRD set, whose system of voice transmission made it suitable for rapid civilian use without the need for extensive training. The local OUT stations were operated by civilians but the control IN stations had Royal Signals or ATS operators from Auxiliary Units (Signals). The network was also dependent on a continuing Royal Signals support to ensure its directional aerials maintained a link to the IN station, which were based at army HQs (until 1942 in surface huts vulnerable to dive bombing). As the IN Stations were expected to move with army HQs during a rapid blitzkrieg, it is likely that the OUT Stations would quickly become out of touch, with the network collapsing in a matter of days. Nonetheless, the network could have provided an important, albeit brief, notification that the enemy blitzkrieg had penetrated a locality. The Special Duties Branch proved to be most important as an internal security body. Although the wireless network became redundant, as the threat of invasion decreased its growing number of agents (over 3,000 in 1944) assisted MI5 and Military Intelligence in eavesdropping on the loyalty of the British populace and any loose tongues in the troops massing for D Day. This was the main contribution of the Auxiliary Units singled out for praise at its stand-down in 1944.
HOME GUARD OSTERLEY TRAINING SCHOOL
The unofficial guerrilla training school established by Tom Wintringham and a number of ex-International Brigade veterans in July 1940 is often considered something of an aberration, shunned by official circles. In the summer of 1940, however, it trained more guerrillas than the Auxiliary Units and there is a suspicion that, whilst MI5 were deeply suspicious of its communistic leanings, SIS saw the school as a useul source of future partisans and may have provided some assistance in methodology. Its instructions to discard uniforms, blend back into the community and organise secret cells of 2-3 men is more akin to SIS than to War Office methodology. See HERE for further details.
The Home Guard in general was greatly influenced by the teachings of Osterley. Although its primary role was seen as static defence to the 'last man and last round', it also maintained a more mobile harassng role as the circumstances allowed. To the frustration of the War Office, such operations acquired the label of 'guerrillas' and the term itself was banned from use in the Home Guard during 1942/3!
