A transcript of this diary is now available for download from Documents and Articles - Miscellaneous Documents Section. A number of personnel are named in the document and may prove helpful in tracing relatives who were in the regiment at the time.

Thanks very much Mike & co, that should be very interesting reading indeed.
What a wonderful forum/site this is !

Here's a commercial website that carries names of some soldiers of many British Army units including a few from the 13th (Forest of Dean) Battalion of the Glostershire Regiment; it may be useful for researching names altho I cannot vouch for the quality of the photos etc that may be bought, I am not linked in any way to the website and have never bought their downloaded products.

My goodness me, transcribing this was a labour of love, well done and thank you for the hard work.
