361 Lancasters and 14 Mosquitoes of 1,3,6 and 8 Groups carried out the first large raid on this target for a year. 18 Lancasters were lost..."
My Uncle received Service Awards: 1939-45 Star Defence Medal, Canadian Volunteer Service Medal with Clasp and War Medal 1939-45. Medals forward to my dad.
He was laid to rest at War Cemetery at Dortmund Germany and later re-interred in the Reichswald Forest British Military Cemetery ( 3 miles southwest of Cleve, Germany. I had the Grave #, Row & Plot info.
I think of him every Nov 11th.
