It may be possible to identify 9259 Cpl J Wright in the Supplementary Photograph of those men of C & D Companies, which was posted under 17 Platoon, E Company, 17th Manchesters on 8 August 2015 by Tim Bell, as Cpl Wright is the only full corporal listed as being in the supplementary photographs in the rolls of 9 to 16 Platoons, inclusive. The only corporal in the C & D Company Supplementary Photograph is in the back row, third from the right.
Having said that...., both medal index card and medal roll entries for 9259 Joseph Thomas Wright, 17th Manchesters, list him as a private. A possible explanation might be that he had been promoted corporal before the 12 Platoon roll was compiled and was then reverted to private before the Battalion went overseas, never regaining his former rank. It is also worth noting that a total of one corporal, nine lance corporals and 67 privates are said, in the 9 to 16 Platoon rolls, to appear in the Supplementary Photographs, yet only 42 men are in the C & D Company Supplementary Photograph.
Is it 9259 Joseph Thomas Wright third from the right in the back row of the C & D Company Supplementary Photograph? Maybe.
