13 August 1977,
Some 500 National Front neonazis attempted a march in Lewisham’s working-class district in London, sponsored by 5,000 police officers. However, 4,000 people willing to face them cut the way. The event is remembered as a battle of Lewisham. There were major disturbances, 214 arrested and there were 100 wounded, but in the end the fascists did not pass.
