My father Jack Lee, was also a RASC ambulance driver and also served in N africa, he was rescued from St Nazaire on the 17th June 1940 and was at D day too, was injured a couple of time finally loosing an eye toward the end of 1944 when a sgt, acting W/O attached to Highland Div. Records abound for those who died but the living is proving a problem, unit diaries a VERY expensive, I was quoted £1700 by the records office, and service records can take up to a year and contain very little information about units and movements.
What records do exist are confusing and in some cases totaly wrong.
