First of all my name is Edward Chilcott, had some trouble registering for this website and ended up using a nickname.
HDA is ex RFC but happily was not lost during WW2, but went on to live healthily until 1969. In fact he was not in active service in WW2 as he was too old to be called up and was employed in essential occupation.
He enrolled in RFC in 1918 and a year later he sailed on HMS Riviera (which is reported to have been adapted for use as the first aircraft carrier) to the Dardenelles to fight for the White Russians against the Bolsheviks. Returned to England via Malta and France in May 1919. In the RFC his Aviators Certificate was no 7660 and issued 13 March 1918.
In 1919 he joined a food provision merchants, John Loudon and Co, and remained with them until he retired in 1969, 50 years of service.
During WW2 he worked closely with the Ministry of Food and after the war he set up the importing of Danish bacon products and was also one of the first civilians to travel to Poland to establish links between Poland and the UK. In 1969 he was awarded the Order of the Polonia Restituta, a highly regarded award for a non Polish citizen.
His only active involvement in WW2 was in the Home Guard in London.
The information earlier in the thread re his DOB is correct and he died 27 November 1969. In 1918 he lived in Blackheath and died whilst living in Eastbourne.
My mother Angela, aged a youthful 79, recollects that other than his time in the Dardenelles he may have been in service in France. From information she obtained from National Archives (inc his service record) he seems to have had a few postings with various "wings" and squadrons and she also thinks he may have been involved in a crash, but escaped unscathed. We do not believe he was awarded DFC.
Hope this is of interest in your enquiries, we have a lot of photos, docs etc, let me know if you want any additional details.
