I think you should be able to take the summary and relate it to chunks of the detail which is adding really only locations in some cases and refining the detail of dates of movement. You'll note that some of the sheets are clearly copies, contrast the entries in different hands with the entries made by the same hand spanning a couple of years.
Of new interest is the medical assessment in March 1940 of A1 and later admissions to hospital and the number of the ITC that I called “other” initially (41 ITC at Camberley Surrey). The references to Xiii List and Y List are among the ways of categorising a soldier who was not with his permanent unit for whatever reason – a purely administrative thing.
What we both had read as Le Centre after France is revealed to be No 4 Centre AMPC not leave centre. This was at Clacton, a training and admin centre for AMPC troops. The record is remarkably clear including unit stamps so when he moved from AMPC to the Seaforths is clearer. One has to understand that putting on the uniform of the Seaforths is not the same as joining a Seaforth battalion. He went to 11 ITC at Fort George, was posted to 41 ITC at Camberley and then back to 11 ITC in the period Jan to Aug 42 including a spell in hospital in Glasgow (it looks like).
He was also appointed Acting Unpaid Lance Corporal in Jan 42, reverts to Private in Aug 42, reappointed in Dec 42 and manages to hang on to the stripe until May 43.
In the broadest of outline, your man worked as a labourer very briefly with the RE, then became, with his unit, a Pioneer doing airfield construction in France, evacuated after Dunkirk, transferred to the infantry and spent the bulk of his time, when not on the run, at Fort George as one of the support soldiers at the ITC. Just before the 7th Battalion went off to war in June 1944 he was court martialled, released and then discharged in May 45.
My suggestion would be to review the sheets against the summary, the 29 Coy summary sent separately and the above and then see if there are specifics you are still not clear on. I would say though that you’ll note that nowhere is there a column for “reason why”. You might like to consider getting the war diaries I have cited. A diary for 10 Group Airfield Construction is cited in the 29 Coy summary.
