As part of my research, over the past year I've been slowly peicing together the (1st) Battle for longstop 22nd-25th Dec 1942. Now I'm not sure I can get any more information then I already have... but there is one thing nagging me that some of you shell heads may be able to help me with. During the 1st Guards Bde Attack Longstop, the atttack was supported by the 14/16 (Med) battery (25 pndrs) and the 36 F.A. Bn (heavies) and the 32 F.A. Bn. However the 14/16 diary for December is missing from TNA (WO 175/368), and their parent unit they were temporrarally attached to has nothing useful. My question is: Unfamilair as I am with artillery, who were the 36 and 32 F.A. Bn, were they an american unit? If not, did an artillery Bn keep a war diary? Because I can't seem to find one at TNA. Secondly, is TNA the only place for artillery diaries? or is there an equivilent to the guards regimental headquarters who might have a copy of the 14/16th's diary?
