It's a propaganda piece from wartime British government. It's probably mostly intended for the American audience. Its main goal is to rally support and show the resilience of the people in the face of overwhelming force. It's narrated by war correspondent Quentin Reynolds who gives the tone of an old fashion cigar chomping reporter. The main question is whether this actually worked. It probably was very effective in creating sympathy for the British side in America. That is all that matters at this time.
