It was common belief that the German pilots used Dublin (it was not in blackout) to find Liverpool. The decoy fires lit on the Dee shores were completely ineffective.

Interestingly there were reports of parachute land mines dropped on Liverpool and Wirral supposedly designed to explode upon rooftop contact. Actually they were shipping mines intended for the Mersey but aiming accuracy was poor to non-existent. My father worked maintaining Minesweepers at the docks after he was invalided out of the Merchant Navy. Wallasey Ferries had a contract from the Admiralty. They were kept pretty busy, the minesweepers engine mounts took quite a battering - though the sailors did manage a little bit of blackmarket trawling now and then.
