is about what happened to Halifax HR793 on that raid.
Included in the description is this list of waypoints of the route.
"The route was 5134N 0330E, 5059N 0626E, Wuppertal, 5120N 0721E, 5033N 0723E, 5038N 0600E, 5122N 0320E."
I used Google Maps to find towns near the waypoints.
5134N 0330E (Domburg), 5059N 0626E (Ameln), Wuppertal, 5120N 0721E (Gevelsberg), 5033N 0723E (Bremscheid), 5038N 0600E (Eupen), 5122N 0320E (near Knokke-Heist)
