Sgt Stephens was the rear gunner of Avro Lancaster I HK650 AP-T of 186 Squadron, which was lost on a mission to bomb the Hohenbudberg railway yards at Krefeld. The Lancaster exploded after being hit by flak, and debris was scattered over a large area of Schwafheim, just north of the target area. All seven crew were killed.
