The service details of Private W.J. Polkinghorn have not been traced. He entered France 19 April 1915 therefore it seems that he went with 6/DLI and the 50th Division. Private W.J. Polkinghorn was transferred to 1/5th DLI (service number 7402), 1/7th DLI (7402) the Labour corps (409042) and finally to the 23rd Battalion, the Lancashire Fusiliers, regimental number 238231. However, the dates he was transferred are unknown. He was killed in action 27 September 1918.
The 23rd (Service) Battalion, the Lancashire Fusiliers was formed in France in May 1918 as 4th Provisional Garrison and came under the orders of 176th Brigade, 59th (2nd North Midland) Division. It was transferred to 121st Brigade, 40th Division 19 June 1918. In September 1918, the 121st Brigade comprised:

Following heavy losses during the Battles of the Lys and the Division was reduced to cadre. A number of Garrison Guard Battalions joined during June and were converted to fighting units. From mid July 1918, the Division once again took part in active operations. 
The Final Advance in Flanders commenced 28 September 1918 with the Battle of Ypres. The 40th Division was part of the XV Corps, Second Army. British infantry assembled in heavy rain on 27 September and attacked behind a fierce protective artillery barrage before light at 5.20am, the following morning. Despite the difficult ground rapid progress was made.
The 23/Lancashire Fusiliers War Diary for the month of September 1918 and the Regimental History have not been researched therefore the circumstances of his death remain unknown.
Later research records that 27 September 1918 23/Lancashire Fusiliers lost 17 Other Ranks killed in action or died of wounds including Private W.J. Polkinghorn. Between 27 and 30 September 1918, 22 Other Ranks were lost.

After the Armistice, over 700 graves were brought into it from the battlefields of Steenwerck, Nieppe, Bailleul and Neuve-Eglise. There are now 1,704 Commonwealth servicemen of WW1 buried or commemorated in the cemetery.
