The Bethnal Green crush
On 3 March 1943, a crowd of people entered Bethnal Green tube station, which was used at the time as an air-raid shelter. An anti-aircraft battery, a few hundred yards away in Victoria Park, launched a salvo of a new type of anti-aircraft rockets, causing the crowd to surge forward. A woman tripped on the stairs causing many others to fall. Three hundred people were crushed into the stairwell, 173 of them were dead at the scene.
On the night of 13 October 1940 a German bomb fell at Bounds Green tube station killing 16 people.
