Dr Diamond was in the basement of an ARP post, talking to a councillor and a Dr Wheatley, who had just arrived in Hull to take over as Casualty Officer, when it was demolished by a direct hit. When the bomb exploded Dr Diamond took the full blast and was killed instantly, two soldiers in an adjacent car park and PC Robert Garton who was on duty at the door of the ARP post were killed and no trace of the policeman was ever found.
118 tons of H.E. were dropped. Results were difficult to observe on account of darkness and intense searchlight concentration, but reports indicate that a large proportion of the bombs were dropped on that area of the docks in which these battle cruisers were situated
