For many First World War families, the research journey begins with almost nothing.
No surviving service papers. No diaries. No letters home. Sometimes all that remains is a name, a regiment, perhaps a grave reference and — if researchers are lucky — a service number.
That was exactly the situation with Private Henry John Crips of the London Regiment.
The surviving details from CWWG are remarkably limited:
* Henry John Crips
* Private
* Service Number: 4677
* 24th Battalion, London Regiment
* Died 27 September 1916
* Buried at Abbeville Communal Cemetery Extension
At first glance, it might not seem enough to build much of a story. Yet this is precisely where service-number and battalion analysis becomes incredibly valuable.
Using the Army Service Explorer tool on British Army Service Numbers, we can begin reconstructing the outline of Henry’s wartime experience — even without a surviving service record.
Starting With the Service Number
The first step was entering Henry’s service number — 4677 — into the tool.
Immediately, several things begin to stand out.
First, the number is extremely low by First World War standards. This instantly suggests an early wartime enlistment into a Territorial Force battalion rather than a later mass wartime allocation.
Second, the tool identifies the battalion as part of the London Regiment structure. While all London Regiment battalions technically belonged to the Territorial Force, the numbering still helps narrow down roughly when a soldier joined and what sort of wartime intake he likely belonged to.
This is one of the biggest misconceptions surrounding First World War research. Many people assume a service number is simply an administrative detail. In reality, British Army numbers often contain clues about enlistment period, recruitment patterns and even the type of soldier involved.
In Henry’s case, the number strongly suggests service beginning around early 1916.
That timing matters enormously.

The Army Changes in 1916
By the time Henry likely entered the army, Britain had already been at war for well over a year.
The enthusiastic volunteer rush of 1914 had faded beneath the grim realities of trench warfare and catastrophic casualty figures. Entire battalions had been devastated on the Western Front and the British Army desperately needed replacements.
In January 1916, the Military Service Act introduced compulsory military service for single men aged between 18 and 41.
This represented a seismic shift in British society. For the first time in modern British history, men could be legally compelled to serve in the army during peacetime legislation extended into wartime.
Using the likely enlistment window generated through the service-number analysis, Henry John Crips appears to belong to this first major wave of conscription-era soldiers entering the army during 1916.
That single insight transforms the story immediately.
Rather than being one of the eager 1914 volunteers responding to Kitchener’s famous recruitment posters, Henry was likely part of a younger generation entering the military after the war had already become industrialised, attritional and brutally deadly.
At just 19 years old, he would have been among the youngest soldiers sent to France during the Somme offensive.

Recruitment Hotspots and Local Identity
One particularly useful feature of battalion-level analysis is identifying likely recruitment geography.
The Army Service Explorer tool links the 24th Battalion, London Regiment with recruitment patterns around areas such as Finsbury, Kensington and Hackney.
This local identity was incredibly important during the First World War. Territorial battalions often drew heavily from specific districts, workplaces and communities. Men regularly served alongside neighbours, relatives and school friends.
Even as the war progressed and recruitment became more centralised, battalion identities still retained strong regional characteristics. Other regiments based around the capital had varying recruitment areas for example the Middlesex had a Public Schools Battalion whilst the KRRC recruited nationally and from across the Empire.
This means Henry was not simply “a London soldier” in the broad sense. He was probably part of a very specific social and geographic world within wartime London.
That ability to narrow the likely recruitment environment from only a service number is exactly where this kind of research becomes powerful.
And with the London Regiment, that range is enormous.
Using Battalion Analysis to Trace the Somme
The next stage is moving beyond the number itself and into battalion history.
This is where the battalion lookup side of the tool becomes particularly valuable. A service number may identify the soldier, but the battalion tells us what that soldier actually experienced.
Henry died on 27 September 1916.
That date places the 24th Londons squarely within the Battle of the Somme — one of the most infamous campaigns in British military history.
The Somme offensive had begun on 1 July 1916 and by September had already consumed hundreds of thousands of casualties. What was originally intended as a breakthrough offensive had descended into a brutal war of attrition fought across devastated landscapes of mud, shattered villages and endless artillery bombardment.
By the autumn of 1916, many battalions were shadows of their original wartime strength. Casualties forced constant reinforcement drafts into front-line units, often made up of younger recruits and recent conscripts.
That wider context aligns closely with the conclusions suggested by Henry’s service number.
The tool therefore allows us to connect multiple layers together:
* likely enlistment period
* probable recruitment geography
* wartime intake type
* battalion operational history
* likely campaign involvement
*Casualty likelihood
Even without surviving personnel files, a coherent outline of service begins to emerge.
The Reality of Researching “Burnt Records”
One reason tools like this matter is because so many First World War records no longer exist.
During the Blitz of 1940, a huge proportion of British Army service records were destroyed by German bombing. Researchers today refer to these missing files as the “Burnt Records”.
For countless soldiers, the complete paper trail simply vanished.
This often leaves families believing research is impossible.
In reality, surviving fragments can still reveal a great deal when interpreted correctly. Service numbers, medal rolls, battalion histories, casualty records and cemetery information all combine to help rebuild at least part of the story.
The important thing is understanding that military research is rarely about achieving perfect certainty.
That is why the Army Service Explorer tool deliberately works as a “compass rather than a map”. It identifies the most likely pathways and interpretations while still acknowledging uncertainty where appropriate.
In Henry’s case, we cannot say with absolute certainty exactly where he enlisted or the precise circumstances of his death. However, the evidence strongly points towards:
* an early 1916 enlistment
* Territorial Force service in the London Regiment
* recruitment linked to central/north-west London districts
* deployment during the Somme campaign
* death during one of the most intense periods of the battle
That is already far more than many families expect to uncover from a single surviving service number.
Abbeville and What a Grave Can Tell Us
Henry is buried at Abbeville Communal Cemetery Extension in France.
Cemetery locations themselves can sometimes offer further clues.
Abbeville became a major medical and logistical centre during the war, containing numerous military hospitals. Soldiers buried there were often those who died of wounds after evacuation away from the immediate front lines.
While this is not definitive proof in Henry’s case, it introduces another possible layer to the story. Rather than being buried directly on the battlefield, he may have reached medical treatment before succumbing to his wounds.
Again, this demonstrates how multiple smaller clues can collectively help reconstruct a soldier’s wartime journey.
Why This Type of Research Matters
The story of Henry John Crips demonstrates something important about First World War research.
Many people assume military history research only works when complete service papers survive. In reality, even minimal surviving evidence can still reveal remarkable detail when analysed properly.
A single service number can sometimes help identify:
* enlistment period
* battalion
* recruitment area
* likely theatres of war
* whether a soldier was volunteer or conscript
* probable wartime experiences
That is exactly what battalion and service-number analysis is designed to do.
In Henry’s case, the surviving evidence paints the outline of a young London Territorial soldier caught up in Britain’s transition from volunteer army to mass conscription. A teenager likely recruited during the manpower crisis of early 1916, sent to France during the Somme offensive and dead before reaching his twentieth birthday.
Without battalion and service-number reconstruction, he risks becoming little more than a name on a Commonwealth War Graves headstone.
With it, at least part of his story can still be told.
If you are tracing a First World War ancestor and only have a service number, our tool can help identify likely battalions, enlistment periods, recruitment areas and wartime service patterns — even when full service records no longer survive.
