Was your ancestor captured in 1914?

I've just added my latest roll of 1914 other rank prisoners of war on my army service numbers blog, this time for the Irish Guards. 

I have noticed that in most cases where it is indicated on a medal index card that a man was a prisoner of war, that capture took place in 1914.  This holds true for the majority of regiments although of course there are exceptions and it doesn't necessarily follow either that all 1914 PoWs have this information stated on their cards. John Roache, above, is a case in point, although note that this card does not include details of his 1914 Star either.
