Pahlevi reports from the UK National Archives:
There are two from Lt. Col. Ross (one for March - April and the other for August – September 1942).
There is also a 3rd report from Lt. Col Ata-Ullah from the Indian Field Ambulance service.
All fascinating with extremely valuable information on the arrivals in Pahlevi. Hopefully provides many of the missing pieces in your research.
Ross mentions a German plane flying overhead in September. Maybe the one which took the aerial photos of the camps!
