His number is actually quite early in the sequence which, although allotted in number order, were not in a regular sequence as intakes depended on the demands of the service and conscription had begun in September 1939. There is also the possibility that he volunteered rather than waiting to be conscripted. The list of where he fought suggests he was with 1st Battalion throughout. 1st Battalion effectively ceased to exist after holding the line at Dunkirk so the period late 1940 onward would have seen great efforts to re-form the battalion in time for 1942 and North Africa. I'd propose that the report holds water.
