Sourced from the WO12 records held at the National Archives in England, the records comprise "selected muster books and pay lists of the Cavalry, Foot Guards and regular infantry regiments of the line. Also included are special regiments or corps, colonial troops, various foreign legions and troops, garrison battalions, veteran battalions and depots".
The records may contain the following details:
- start date
- end date
- where stationed

Note that Ancestry also some exceptionally useful British Army records covering the same period on its worldwide subscription, namely the Canada, British Regimental Registers of Service, 1756-1900 collection of depot registers, searchable at http://search.ancestry.co.uk/search/db.aspx?dbid=3253. Despite the title, the records are most certainly British - to give an example of how useful they are, read my blog post at http://britishgenes.blogspot.co.uk/2014/05/ancestrys-canadian-british-regimental.html.
