The Bethnal Green disaster of 3rd March 1943 was a defining moment in the history of the East End of London.
Witness Marlene Deathridge recalls "the evening of March 3 had been dreary and wet. At. 8:17 pm the air–raid siren sounded. Just as on previous nights, a large proportion of the population hurried for the subterranean security of the tube station. Today, with streetlights on every corner and neon shop signs, it is difficult to imagine the dense gloom of the blackout, but for those racing to the underground it was like running through ink. Those journeys, coupled with the shrill wail of the alarm signal, were for many the most frightening experience of the war."
