York Blitz 1942 Baedeker Raid 

In the early hours of April 29, 1942, the Second World War came to York in the most violent manner possible.
For two hours or more, bombs rained down on the city. By the time the final all-clear sounded at about 4.45am, 94 men, women and children in the city and its suburbs had been killed, or left so badly injured they were later to die.
This act came to be known as the Baedeker Raid
