Hi Hepburn
113 Bty., 27 Lt A.A.Regiment., Royal Artillery
Is the 113 Battery which was part of the 27th Light Anti Aircraft Regiment, Royal Artillery
The Regiment sailed to Noth Africa, leaving Glasgow, on 15th August 1941, arriving at Suez on 1st October. The Regiment was part of 12th Anti-Aircraft Brigade and as such was responsible co-ordinating ground defence of airfields as well as Anti Aircraft defence in general.
I am currently working on researching the history of the regiment, which comprised of 107, 113 and 149 Batteries, as my Grandfather served with 107 Battery, which was captured at the fall of Tobruk in June 1942. 113 Battery did not suffer the same fete, and went on to see action in northern europe.
Some further information can be found at
http://www.27lightantiaircraft.co.uk/index.html but this work in progress and I haven't got as far as looking too much at 113 Battery.
It is possible to view the war diaries for the Battery at the public records office, Kew, which would give you a great deal more information.
