During WWII, Finland was twice involved in military confrontation with the Soviet union. For the capital, Helsinki, the most intense air raids and bombings occurred in February 1944, a campaign which is usually referred to as The Great Raids Against Helsinki. These amazing photographs, created by the Finnish Defence Forces Combat Camera unit, mash up haunting photos of wartime destruction with modern pics from a couple years back, in nice black and white plus colour images.
The USSR was under the impression its bombing campaigns were more successful and expected Helsinki to be pretty much gone by the end of the war. The Soviets didn’t learn of the relatively limited damage until after the war when Allied Control Commissioner Andrei Zhdanov visited Helsinki.
