According to the Unit Daily Diary, at 1750 hours on 1945-06-23 Sergeant J. Bennett drowned in Mill Pond, Abbotsford, British Columbia while swimming.
However according to his sister, he was a very bad swimmer and actually afraid of the water. Mill Lake was a centre of logging at the turn of that century and there was a small gauge logging train that skirted across the West end of the lake. The trestle that crossed the water was then more than 60 years old and very depilated. Several RAF Airmen were walking along it when the portion they were on collapsed. This is how he drowned. (this information was provided by Michael DesMazes.)
