11am

The ultimatum expires without a response from Germany.

11.15am

Prime Minister Neville Chamberlain broadcasts to the nation the news “that no such undertaking has been received and that consequently this country is at war with Germany”. The broadcast is a deep humiliation for the Prime Minister, whose policy of appeasement has been an abject failure.

“You can imagine what a bitter blow it is to me that all my long struggle to win peace has failed,” he tells his people. “Yet I cannot believe that there is anything more or anything. different that I could have done and that would have been more successful.”

Among those listening are 19-year-old Bob McDougall. “I was at camp with my territorial unit and after church parade we were supposed to catch the train home to Liverpool,” he recalled. “Instead we listened to the wireless and heard that we were at war. Someone said ‘we’re not going home now, we’re here to stay’. He was right. It was a fortnight’s camp that turned into six years.”

It was a false alarm, but perhaps it was to get us used to the warning sound.”
