Of the approximately 150 men who I believe to have transferred to the 9th Devonshire Regiment, only one service record survives. However it is still possible to view their entries on the medal rolls, and the smattering of Silver War Badge entries. Additionally, one among their number subsequently joined the RAF, and has some service details also available to view online.
Cross referencing this gives us a little more information, but also throws into question my assumption that Grandad was initially in the KSLI before being transferred to the Devonshires. I have factored all this into his entry.
