On 7 December 1941, as Japan struck Pearl Harbor, London was deep in its third winter of war: bruised, blacked out, queueing for scraps, shrugging off sirens. In this episode of London Calling we take the city’s pulse on that day. From wardens chastening Noël Coward to milk carts pulled by dogs, from Advent sermons to Fleet Street’s midnight shock, we watch London discover the attack that would change its fate. A fogbound capital learns, almost in its sleep, that it’s no longer alone.
