Worcestershire Regiment

Hope someone can help! I.m very new to this site. I am researching my Grandfather who served in the Regiment from 1916 -1918. He was a POW in Kranichfeld from 27.05.1917, until the end of the war.
I have found some military records via the web, but wonder if anyone can help point me in the direction of where I might be able to find any more information. i.e. where he was posted etc?
Thanks

Hi,

He was with the 7th Battalion Worcestershire Regiment. On the 21st May 1917 the battalion was in the front line east of Lagnicourt in front of the Hindenburg Line. Between the period 21st May to 1st July 1917 four men were reported missing.

Regards,

Louis
