On 10th August 1974, the then Essex Historical Aircraft Society carried out their first major excavation the remains of which are displayed at the museum. The team on the dig were ; Fred Dunn, Dave Campbell, Roger Pickett, Robin Hill, Ron Wingrave, Chick Lowin and Colin Wingrave .

The dig started at about 8.30 am and at a depth of three feet ( 1mtr ) the smashed remains of the Rolls Royce Merlin came to the light of day for the first time in thirty four years. Ravaged by corrosion most of the outer casing had rotted away. Other finds include the gun firing button from the spade grip, engine mounts, Rotol propeller boss and the makers plate, confirming this as the aircraft flown by Pilot Officer; Camille Robespierre. Bonsigneur.

The excavation of this Battle of Britain casualty was completed by 16.30 hrs on the same day.

The picture above taken looking west at the dig in 1974; The site is now right beside the busy A12 Chelmsford by-pass, between Margaretting and Galleywood the crash site only just being missed when the road was built in the 1980s, 50 metres more to the west and it would have covered a Battle Of Britain crash site for ever. I very much doubt that people driving past know what history is a matter of yard's away!

CAHS Regina member Will Chabun writes: Within one week in mid-August, 1990, I received two requests (one from Britain, one from Manitoba) for information on, or a photo of, a young man who lived here for more than 60 years ago. What gives?

The young man was Pilot Officer Camille Bonseigneur, who came from rural southwest Saskatchewan to Regina in the late 1930s and worked briefly for a car dealership, living briefly in at 1827 Osler St.

Then (as was quite common in those days), he enlisted in Britain's Royal Air Force, when it was considerably ahead of our own air force in preparing for the European war that everybody knew was coming.

When the war broke out, young Camille was training as a pilot.

By the summer of 1940 -- precisely 60 years ago this month -- he was flying Hurricane fighters with the RAF's 257 Squadron, one of "the few" who saved Britain from the rampaging, previously undefeated Luftwaffe.

Had Britain fallen, then what? America was not in the war. Hitler would have had a free hand against Russia and might have won the Second World War. The people seeking information on him, and others who fought in this epic battle, are historians aware of its enormous significance.

Incidentally, on Sept. 3, 1940, young Camille Bonseigneur -- thousands of miles away from home -- was shot down and killed.

He was 22.
