What happened in Liverpool on the night of 3rd May 1941? Certainly there was a very heavy (for the period) German air raid in which over a thousand people were killed. While there were a number of well-known incidents, there are some things that have no adequate explanation though they must have been the subject of inquiry at the time. A large area of the city centre, including a vital telephone exchange, was destroyed in a conflagration that was scarcely attended by the fire service. An ammunition ship burned for hours before blowing up, again without anyone (except a few very brave auxiliary firemen) doing much to prevent this. "There was a muddle over bringing in reinforcements which either did not arrive or were extremely late." It may be that some of these things could be readily explained, but I suspect that the explanations would have come to light long ago if they were not felt to be a bit embarrassing.
