Private Willaim Cyril Williams had the early regimental number 5219 and later regimental number 108578. He served with the 10th Battalion, The Sherwood Foresters during the Great War (1914-18). 

The 10th Battalion formed on the 13th of September 1914, for the Great War. The Battalion joined the 51st Brigade of the 17th Division. The 10th Battalion landed at Boulogne, France, on the 15th of July 1915.  

It is unknown when William joined the Battalion. However, the Battalion saw much action in the Ypres Salient and so William would have seen action there. The Battalion saw action at battles on the Western Front including: Battle of Deville Wood (1916), The First Battle of Passchendaele (1917) and Battle of Cambrai (1918).
