The nations reacted quite differently. Denmark surrendered two hours after invasion, having lost just sixteen men. They sought to avoid civilian casualties and receive favourable treatment from Germany. Norway however, refused to give in and fought valiantly and with the full strength of her limited and badly prepared forces. The Western allies sent military assistance, but the campaign was not effectively run. By 10 June 1940, Norway's official military had surrendered to the attackers, while King Haakon VII and his legal government fled to exile in Britain.
