Age UK in Hull has a map showing the locations and types of ordnance dropped on the city during the blitz. A scanned copy of the map has been publicly available online for many years. The owner of the original map is unknown. The accuracy of the map is also unknown.
Reports by people living in Hull who they or their ancestors directly observed events during the blitz or have come across unexploded ordnance.
