On October 4, 1936, tens of thousands of Zionists, Socialists, Irish dockworkers, Communists, anarchists, and various outraged residents of London's East End gathered to prevent Oswald Mosley and his British Union of Fascists from marching through their neighborhood. 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.
