19 The Gestapo’s most wanted person was New Zealand born British Special Operations agent Nancy Wake. She once killed an SS soldier with her bare hands to prevent him from raising alarm during a raid and led an army of 7,000 against 22,000 German soldiers suffering only 100 casualties on her side. 

When she came to Britain, she joined the Special Operations Executive and became a liaison between London and the local French maquis group. She later became instrumental in recruiting over 7,500 members to the maquis group and also led attacks on German installations and local Gestapo Headquarters in Montlucon. From April 1944 until the liberation of France her maquis fought the Germans causing only 1,400 casualties, with only a 100 on their side. She also gave tactical advice during the strategic bombing of railroads of German occupied Paris.

One time, she discovered that her soldiers were protecting and reluctant to kill a girl who was a German spy when she did the deed instead. Once, to replace the codes her wireless operator was forced to destroy in a German raid she rode a bicycle for more than 500 kilometers through several German checkpoints.(source)

20 The Russians partied so hard after WWII ended that the entire city of Moscow ran out of vodka. 

At 1.10 am on May 9, 1945, when the radio announced that the Nazi Germany officially surrendered to the Soviet Union there was an immense outbreak of celebrations in the nation. In their exhilaration the Russians ran out onto the streets in their pajamas, soon joined by the Allied embassies, and drank to the victory and to those who were killed. A celebratory gun shot was fired and there were search lights illuminating the sky. By the time Joseph Stalin addressed the nation 22 hours later, the entire supply of vodka was finished in the whole country.(source)

21 London only reached its peak population level of 1939, before the WWII, in January, 2015. 

In 1939, London was the second biggest city in the world and by that time it also reached its peak population. But, as the war started, there had been evacuations, the Blitz and people leaving to serve the war effort, though interestingly enough the population started fall after the war ended because of plans and constraints to redistribute population to stop increasing the city’s size. 75 years later, however, by 6 January, the population size has grown back to what it was.(source)

22 Every year, the Netherlands sends 20,000 tulip bulbs to Canada in gratitude for their aid during the Second World War. 

During the Nazi occupation of the Netherlands, Ottawa, Canada, gave shelter to Princess Juliana and her daughters for a period of three years. An interesting incident was when the Princess gave birth to her daughter, Princess Margriet, in 1943 at the Ottawa Civic Hospital, the maternity ward was temporarily declared part of international territory, so that she would be born in no country and would inherit her mother’s Dutch citizenship. After the war, in 1945, the Dutch royal family sent a 100,000 tulips to show gratitude, and in 1946 Princess Juliana sent 20,500 bulbs, to create a display for the hospital, promising to send 10,000 each year. In the next few years, this custom came to be organized as the Canadian Tulip Festival.(source)

23 There was an actual group of Jewish assassins called “The Avengers” who tracked down and executed Nazi war criminals after the war.

After the war, the Nokmim and the veterans of the Jewish Brigade in British Palestine formed Nakam (Revenge), a new group of assassins who targeted Nazi war criminals to avenge the Holocaust.(source)
