Introduction

Whether you're researching a family member who served in World War I or tracing a British soldier from the Napoleonic era, learning how to research the military history of an individual in the UK is a rewarding journey. It helps preserve family heritage and brings untold stories back to life.

This SEO-friendly guide covers everything you need to know — from locating British Army service records to exploring Commonwealth War Graves and regimental diaries.

 

Why Research Military History?

Researching an individual's military history can help you:

  • Understand your family's past
  • Honour the memory of those who served
  • Contribute to historical or genealogical projects
  • Discover medals, battles, and personal stories

Popular search terms:

Step 1: Gather Key Information

Start your search with basic but vital details:

  • Full name (and variations)
  • Date/place of birth
  • Date/place of death (if applicable)
  • Regiment, battalion, or service branch (Army, Navy, RAF)
  • Conflict served (e.g., WW1, WW2, Falklands)
  • Service number (if known)

Tip: Use family documents, medals, old letters, or photos to find clues. Even a regiment cap badge can help.

 

Step 2: Identify the Conflict Period

Knowing the time period focuses your search. UK military records vary by era:

Step 4: Use Regimental and Unit Records

If you know the regiment, battalion, or ship:

  • Look up regimental histories and muster rolls
  • Check war diaries (available at The National Archives)
  • Visit regimental museums (e.g., the Imperial War Museum, Guards Museum, etc.)

Example keywords:

  • “Royal Fusiliers war diary WW1”
  • “British Army unit records 1944”

Step 5: Check Medal Rolls and Awards

Many British service members were awarded campaign medals or gallantry awards. Search for:

  • Medal Index Cards (MICs) – WW1
  • London Gazette – for gallantry citations and commissions
  • Service medals – such as the 1914 Star, Defence Medal, or Military Cross

Search-friendly terms:

  • “British Army medal search by name”
  • “WW2 medals and awards UK lookup”

Step 6: Search Death, Memorial, and POW Records

If the individual died in service:

  • Commonwealth War Graves Commission (CWGC) has graves and memorials worldwide
  • POW records can be found via the Red Cross Archives or The National Archives (WO 344 series)

Use phrases like:

  • “WW1 soldier grave location UK”
  • “British POW records World War II”

Step 7: Cross-Reference and Build the Story

Always double-check facts using:

  • Multiple sources
  • Birth/marriage/death certificates
  • Electoral rolls and census records (especially 1911 and 1921)

Once verified, consider documenting the story:

  • Create a blog post or social media tribute
  • Add the profile to a family tree on Ancestry or Findmypast
  • Share with local historical groups or museums
