WWII Regiment & Corps Library

Trace the wartime service of British Army soldiers through a research library built around the evidence they left behind. Explore regiments, corps and battalions, investigate what an Army service number can reveal, and follow individual units through the campaigns of the Second World War. Each research hub is designed to help turn names, numbers and fragments of family history into a clearer understanding of where a soldier served and what his service may have involved.

What is the Library?

The WWII Regimental Research Library brings together our expanding collection of research hubs covering the regiments and corps of the British Army during the Second World War. Divided into ten sections, it provides a structured route through an Army in which historic regimental identities existed alongside armoured formations, specialist corps and an increasingly centralised system of recruitment and wartime service.

The individual hubs take researchers beyond identification alone. They examine service-number evidence, recruitment patterns, wartime organisation, battalions and units, campaigns, casualties and potential medal entitlement, while also highlighting the limitations and interpretation problems that can make Second World War research difficult. Case studies and practical research guidance demonstrate how different pieces of evidence can be combined when reconstructing an individual soldier’s service.

Alongside the Army Service Explorer, the Library adds depth and context to results obtained from a service number or regiment/corps search, allowing researchers to investigate the evidence behind those findings and follow promising lines of enquiry further.

All 107 British Army units across ten research sections


Explore Scotland’s historic infantry regiments, from the Lowlands and Borders to the Highlands and Islands, tracing their strong recruiting traditions and the soldiers who served with them across the major theatres of the Second World War.


County identity remained deeply rooted in the infantry regiments of Yorkshire, Durham and Northumberland, whose wartime ranks drew together soldiers from the region’s great industrial centres, mining communities, market towns and rural districts.


The industrial heartlands of Lancashire and Cheshire provided recruits for some of the British Army’s best-known infantry regiments, while the Border Regiment drew on the very different communities of Cumberland and Westmorland.


Stretching from Shropshire and Worcestershire eastwards to Northamptonshire, the Midlands encompassed an unusually broad range of regimental recruiting grounds, connecting historic county regiments with soldiers drawn from both the industrial heart of England and its rural counties.


From the populous counties surrounding London to the very different landscapes of East Anglia, this section brings together regiments whose traditional recruiting grounds encompassed some of the most varied communities in southern England.


Coastal ports, naval towns and rural counties shaped recruiting across Southern England, from Cornwall and Devon to Hampshire, Berkshire, Surrey and Sussex, supplying the Army with soldiers from communities closely connected to both land and sea.


Welsh and Irish regiments carried particularly distinctive identities into the wartime Army, preserving long-established traditions and connections with communities across Wales, Northern Ireland and the historic Irish recruiting areas from which many had drawn their soldiers.


From the Foot Guards and historic cavalry regiments to the Royal Tank Regiment and wider Royal Armoured Corps, explore the units that served as infantry, reconnaissance troops and tank crews across the major theatres of the Second World War.


Modern warfare depended upon vast organisations operating behind and alongside the fighting units. Artillery, engineering, communications, transport, supply and mechanical expertise made the Army function, placing specialist corps at the heart of British operations worldwide.


Keeping millions of soldiers healthy, disciplined, paid, fed and trained required its own network of specialist organisations. These corps managed the people behind the Army, providing the medical, administrative and professional services essential to wartime service.

Why is the Library Organised this Way?

The British Army of the Second World War cannot be understood through geography alone. Historic infantry regiments still maintained strong connections with particular counties and recruiting areas, but the Army in which they served had become increasingly centralised. Army service numbers were allocated within a unified numbering system, wartime recruiting became less closely tied to locality, and soldiers could be posted or transferred wherever their skills and the needs of the Army required.

Geography nevertheless remains valuable when researching the infantry. Regimental names, recruiting traditions and local connections continued to matter, which is why the infantry is grouped into broad regional sections. The same approach makes far less sense for the rest of the Army. Guards, cavalry and armoured units followed different organisational traditions, while specialist corps were defined principally by their military role rather than the geographical origins of their soldiers.

The Library therefore uses ten regional and functional research sections rather than forcing every unit into a geographical framework or presenting 107 regiments and corps as a single alphabetical list. This preserves meaningful regional relationships where they can help identify and interpret a soldier’s service, while allowing other parts of the Army to be understood through their role, organisation and wartime function.

Featured Hubs

Explore a selection of our featured Second World War research hubs. Each examines a different part of the wartime Army, bringing together evidence, context and practical guidance for tracing individual soldiers.

Royal Artillery

The Army's largest regiment, providing fire support through field, anti-aircraft, anti-tank and coastal artillery units.

Royal Army Service Corps

Managed transport networks, delivering food, fuel and supplies wherever British forces operated globally.

Royal Army Medical Corps

Delivered frontline medical care, evacuation and hospital treatment, saving countless lives throughout WWII.

Royal Fusiliers

Closely associated with London, and serving across the world during the Second World War.

General Service Corps

Processed recruits before allocating them to the regiment or corps where they would ultimately serve.

Frequently Asked Questions About The WWII Technical Hubs

How accurate is the Army Service Explorer?

The Army Service Explorer uses historical service-number allocations, enlistment evidence and regimental data to identify the likely regiment or corps associated with a Second World War Army service number. It can also indicate a probable enlistment period and provide further research context, but a service number cannot reconstruct an entire military career. Transfers and subsequent postings mean that the regiment indicated by a number may represent only one stage of a soldier’s service. Results should therefore be used as evidence and a starting point for further research rather than as a substitute for an individual service record.

What is the difference between the Army Service Explorer and this library?

The Army Service Explorer is designed to interrogate the research quickly. A WWII service-number search can identify a likely regiment or corps and return information including probable enlistment period, recruitment geography, casualty context, notable campaigns and potential campaign medals. Researchers can also explore the data directly by regiment or corps. The Library provides the deeper research framework behind those results, allowing you to investigate individual units, understand how they were organised and follow the evidence into more detailed lines of enquiry.

Why does the Library include individual hubs if the Explorer already searches by regiment or corps?

Because identifying a regiment or corps is often only the beginning of Second World War Army research. Individual hubs examine what service-number evidence can and cannot establish, recruitment and transfers, wartime organisation, battalions and units, campaigns, casualties and potential medal entitlement. They also highlight problems specific to particular units and use case studies to demonstrate how fragmentary evidence can be interpreted. The Explorer helps uncover useful evidence; the hubs provide the depth needed to understand what that evidence actually means.

What makes these hubs different from other Second World War resources?

These hubs are built around the problems encountered when researching individual soldiers. Regimental history remains important, but it is combined with service-number analysis, recruitment evidence, organisational information, casualty data, medal possibilities and practical guidance on surviving records. Rather than simply asking where a regiment fought, the Library explores how different forms of evidence can be connected, tested and interpreted to reconstruct an individual soldier’s service through the increasingly complex British Army of the Second World War.
