Thomas joined the Lancashire Fusiliers and served with the 3/5th Battalion, Service Number 203089. It is not known when Thomas enlisted, but he would have seen his older brother Frank join up shortly after war was declared.
This Battalion was formed in Bury and later moved to Crowborough as part of the 197th Brigade 66th Division. In March 1916 the barracks were in Colchester and the Battalion were mobilised to France on 1st March 1917. Thomas may have seen action on the Flanders coast or at the third battles of Ypres. It is possible he was involved in the advance on Passchendaele.
Thomas was killed in action, just 19 years old. He is commemorated at the Tyne Cot Memorial, Zonnebeke, Belgium.
Thomas was later awarded the British and Victory medals.
