Sixty nine years ago today a World War Two bomb smashed into Balham High Road, killing residents sheltering in the tube station below.

For years after 64 people were thought to have been killed, and 70 injured, that night.

But the Wandsworth Guardian discovered that three further people died in the tragedy and has been pressing for Transport for London (TfL) to change the memorial plaque at Balham Tube station to include them.

Following an inquiry which led to the Imperial War Museum and Wandsworth Council’s record office, it emerged that the total did not include three Tube workers.

Some 18 months after TfL confirmed it would change the plaque nothing has been done.

This week a spokeswoman for TfL said it was concentrating on refurbishing the station.

She said: “There is a plaque at Balham station to commemorate the tragic loss of life of those sheltering from an aerial bombardment at the station on 14 October 1940.

“The plaque will be corrected in due course to read that 67 people died instead of 64 as was previously believed.”

As Wandsworth people sheltered from an air raid just before 8pm on October 14, 1940, a Luftwaffe bomb smashed into Balham High Road, narrowly missing an bus on route to Vauxhall.

The blast left a crater in the road 50ft wide, into which the bus fell, and fractured water mains and sewers - which began to spew seven million gallons of water, mixed with sand, debris and sewage, into the tunnel.

Within minutes, the water nearly reached the main concourse, some 25ft above, and even reached within 100 yards of Clapham South.
