On the 12th, May, 1944, No. 426 Squadron was tasked with the bombing of the rail yards at Louvain, Belgium, as part of an 120 aircraft raid. Fourteen Thunderbird crews were on the battle order, and each aircraft carried nine 1000-pound bombs and four 500-pound bombs. At 22:05 hours, the detail began taking off on the four-and-a-quarter-hour mission, all aircraft being airborne within fourteen minutes.

Eight of the crews are known to have attacked the target between 00:28 and 00:35 hours on the 13th May.

Halifax LW682/OW-M, with P/O. Bentz and crew never made it to the objective. A Luftwaffe night-fighter ace, Major Martin Drewes, in an Me 110, shot them down near the village of Geraardsbergen. The aircraft crashed into a bog near the River Dender, killing the entire crew. The German records state that the softness of the ground prevented the recovery unit from removing much from the wreck.

The navigator F/O. Taylor, the bomb aimer F/O. Phillips the wireless operator WO1. McIntyre and the flight engineer, Sgt. Ellerslie had each completed two missions. The mid-under gunner, Fl/Sgt. Arbour was on his first mission. The remains of these men were recovered by the Germans at the time of the crash and were buried together in the Geraardsbergen (Grammont) Communal Cemetery, East Flanders, Belgium.

The pilot, Fl/Sgt. Bentz, and the rear gunner, Sgt. Roach, had each completed three operational sorties. The mid-upper gunner, Sgt. Summerhayes, was credited with two operational sorties. The remains of these men stayed lost within their Halifax. In July 1948, the crew posthumously received the Belgian Croix de Guerre with Palm.

Fifty three years later, Jay Hammond a nephew of the pilot Wilbur Bentz, initiated and participated in a search to recover the downed aircraft and the remains of the three crew members.

Working with the Belgian Aviation History Association and the 426 Thunderbird Squadron Association with financial assistance from Canadian Heritage and Veterans Affairs Canada, the Halifax crash site was excavated and the missing airmen’s remains were retrieved.

On November 10th 1997 the bodies of P/O. Wilbur Bentz, P/O. Fred Roach and P/O. John Summerhayes were laid to rest along with their comrades in the cemetery at Geraardsbergen. (courtesy of RCAF 426 Squadron Association)
