Hi Just to let those looking to research this unit or the HAC generally that their journal is available through FindMyPast. There are a number of accounts of the fighting in January 1942 in North Africa (which is what I was looking for) and an overall history in several parts by Kenneth Bolton.
Skoyen, There are nearly thirty threads on this unit, alas under different titles 11th / 11 / RHA / in full etc. The tags return only a few threads. I limited my search to "11 rha" + "ww2talk.com" or "11th rha" + "ww2talk.com". It appears that the HAC have transferred all of their Journals, from October 1923 until Autumn 2021, to FindMyPast, they have an archive, not a museum and all is explained on: British Army, Honourable Artillery Company Journal 1923-2021 | findmypast.co.uk Guidance on the HAC Archives is on: Archives
