Scenes of the "Battle of Stepney" on Sidney Street, East London, on Jan. 2, 1911. The gunfight and fire led to the death of two "anarchists" suspected in the Houndsditch Murders of three police officers. The siege also claimed the life of a London fireman - Superintendent Charles Pearson - who sustained injuries when a wall collapsed. He died several months later. The incident sparked a political row over the involvement of then-Home Secretary Winston Churchill.
