I am trying to find information about the 203 Bty., 68 Lt. A.A. Regt. Royal Artillery. A relative was serving with this unit when he died on 7th April, 1943. I assume he died in the UK as he is buried in his home town, Preston, Lancashire. He is recorded as Kenelem Kelsall, Gunner 1635472. I know nothing more about his military service than I found on CWGC. Casualty Any assistance/guidance would be much appreciated.
