Books photos about executed POWS June 1944

Hi.

I'm looking for books about the Canadian POWS who were executed by the 12th SS Panzer Div June 8, 1944.
My Uncle was one of those soldiers and I'm writing about him. I want to know some of the events of those days in June, and I want to know `facts', not over-dramatizations or `wrong information'.
Judging the nature of this site I'm assuming I can hope to get some good/real info and suggestions on reading/viewing material.

(I'm already waiting to receive copies of `Take No Prisoners' video, and the library is searching for `Conduct Unbecoming by Howard Margolian, so am looking for `other sourse here)

I'm also looking for any photos that specifically include my uncle:

EDWARD SMITH, RIFLEMAN,
ROYAL WINNIPEG RIFLES `Little Black Devils'
`died' June 8/44
service #: H/42084

All mementos, photos, papers were destroyed by housefire so I'm searching via here and other places.

Thank you for any help...and Thank all you soldiers past, present and futurefor all you do and sacrifice.
