Up to 450,000 Poles served in the Wehrmacht, the armed forces of Nazi Germany, during World War II. For years, they were viewed in Poland as traitors. But as an exhibition in Gdansk shows, the truth is more complicated. Anyone entering the first room of the exhibition "Our Boys" in the Main Town Hall branch of the Museum of Gdansk is greeted by dozens of photos showing young men in the uniform of the Wehrmacht, the armed forces of Nazi Germany. Some of the men in the photos are smiling; some look extremely serious; some look sad. At first glance, these photos are nothing out of the ordinary, considering that a total of 17 million men were called up to fight in the Nazi army between 1939 and 1945.
