In the Express & Star 5 April 1918, there is an article announcing that a number of local heroes are going to be honoured and presented with medals at a forthcoming ceremony, arranged by the Wolverhampton Patriotic Committee. Among those mentioned is a Corporal Walsh, M. M.:
In an attack, when the officers of his own and the next platoon were killed, he took charge of both platoons, which considerably helped in the capture of the objective. Later on he was badly wounded.
J. C. J. Elson’s Honours and Awards: The South Staffordshire Regiment 1914-1918 confirms this honour, stating that an A./Cpl. T. Walsh, of the 1st Battalion South Staffordshire Regiment (number 14223) was awarded the Military Medal. This was announced in the London Gazette on 4 February 1918.
Having confirmed his first name as Thomas, using his regimental number, there are two possible men with this name, born in Wolverhampton in 1893 and 1895 respectively (the former being a Thomas Henry Walsh). He does not appear to have died in the war, but without further information I am unable to confirm additional details for him.
