Army Regiments and Corps

Supporting guides

• How Do I Identify the Right Regiment?
  Identify the regiment from the service record, a medal roll entry, or a casualty record, not from a cap badge in a photograph alone. Badges were worn, borrowed and misremembered, while a record entry is dated.
• What Is a Battalion, and Why Does It Matter?
  A battalion is the unit that fought, moved and kept a war diary, while the regiment is the wider family it belonged to. For research, the battalion and its dates matter more than the regiment name alone.
• What Happens When Regiments Amalgamate?
  Amalgamation changes names, numbers and sometimes cap badges, but the dated trail continues through the successor unit. Follow dates and battalion numbers across the change rather than stopping at the old name.
• How Do Corps Records Differ?
  Corps records are organised by function and by unit within the corps, so a signals, engineer or medical trail may run through corps papers as well as unit diaries. Start from the person's unit of posting, then widen to corps level.
• What Can a Regimental Museum Add?
  A regimental or corps museum can add photographs, objects, published histories and local knowledge of a unit. Treat museum material as context and leads, and check personal claims against the service record.
• How Reliable Are Regimental Histories?
  Regimental histories are secondary sources, useful for dates, places and context, but written after the event and sometimes from memory. Use them to frame questions, then verify the points that matter in primary records.
• What About Territorial Army Units?
  Territorial units have their own numbering, mobilisation and record trails, and a person may move between Territorial and regular service. Keep each period dated and separate until the record joins them.
• How Do I Track a Unit Move?
  Track moves through war diary location entries and movement orders, in date order. A unit name without dates can sit in several places in one year, so the date is what fixes the place.
• Can a Unit Nickname Identify a Regiment?
  A nickname can be a useful clue, but nicknames were shared, reused and remembered loosely. Treat a nickname as a lead to check against a record, never as proof of a unit.
• What Does Home Service Mean in Records?
  Home service means service in the United Kingdom rather than overseas, and it appears as postings to home units, depots and training establishments. It is still service, and it still leaves a record trail worth following.
• In What Order Should I Research a Unit?
  Work in this order: service record, then war diary for the battalion and dates, then regimental museum and published history. That order keeps the person anchored before the unit story takes over.
