Russian soldiers are pictured next to the Reichstag building in this undated photo taken May 1945 in Berlin. Some 70 years on from the Battle for Berlin, instrumental in the end of World War II, Reuters photographer Fabrizio Bensch unearthed pictures by Red Army photographer Georgiy Samsonov, showing his portrayal of a city laid siege. Bensch bought an exactly equivalent FED camera, a Soviet copy of the German-made Leica II, choosing to use black and white film to capture images of the self-same locations he detected his way to in modern-day Berlin.
