I was asking for a source that those were actually used on british cities. That article sounds like bombs that were supposed tk detonate not the ‘ambulance killers’ you say were used.

>When explosive devices failed to detonate

From wikipedia: The Royal Air Force began bombing military targets in Germany, such as docks and shipyards, in March 1940, and began targeting Berlin in August 1940.

Im sorry Churchill’s unpopular warmongering killed so many of your people.
