On enlistment, an attestation form was completed for each soldier. These have mostly been lost, but a summary of their contents was recorded in a series of volumes of Army Book 358, in
accordance with the Army Order 338. These volumes were used as a reference source to record an abbreviated service record by serviceman - and it is these that we have digitised.
There are also a few volumes recording Transfers which record servicemen transferred into the Corps, and confusingly this could include servicemen who originally enlisted in the Royal
Army Service Corps, transferred to another regiment and then back to the Corps. In this case there will be may be 2 or more references to an individual serviceman.
It appears that Army Book 358 was in use before August 1920, as there a number of enlistment books held at The RLC Museum which record details in a slightly different format to those used
for the "Army Number" post August 1920. These appear to record attestations prior to August 1920. In many cases, servicemen recorded in these books were allocated a permanent
Army Number, but for some this does not appear to have happened - often for the obvious reason that they were discharged prior to August 1920. This series of volumes is not complete.
We believe that they were only in use after the end of World War 1 up to August 1920 - so they will not necessarily record the regimental number that a servicemen held during the active
service in WW1.
