This clash would eventually be known as the Battle of Cable Street: protesters formed a blockade and beat back some three thousand Fascist Black Shirts and six thousand police officers. To stop the march, the protesters exploded homemade bombs, threw marbles at the feet of police horses, and turned over a burning lorry. They rained down a fusillade of projectiles on the marchers and the police attempting to protect them: rocks, brickbats, shaken-up lemonade bottles, and the contents of chamber pots. Mosley and his men were forced to retreat.
In "Antifa: The Anti-Fascist Handbook," published last week by Melville House, the historian Mark Bray presents the Battle of Cable Street as a potent symbol of how to stop Fascism: a strong, unified coalition outnumbered and humiliated Fascists to such an extent that their movement fizzled. For many members of contemporary anti-Fascist groups, the incident remains central to their mythology, a kind of North Star in the fight against Fascism and white supremacy across Europe and, increasingly, the United States.
