It's the 70th anniversary of one of the darkest days of the Second World War, when Allied planes bombed the medieval German of city of Dresden into oblivion. To commemorate this tragic event, a photographer has revisited the sites to compare archived historical photos with present day scenes.
These images were created by Getty Images's photographer Sean Gallup.
In a series of four raids that transpired in the dying days of the Second World War, Allied bombers comprised of British and U.S. forces dropped more than 3,900 tons of high-explosive bombs and incendiary devices on Dresden. The ensuing firestorm consumed over 1,600 acres of the city center, killing an estimated 22,7000 to 25,000 in the process. Many of those killed were refugees who were fleeing military actions elsewhere in Germany.
It's one of the most notorious and controversial operations conducted by the Allies, who claimed the city was a military and industrial target. Critics contend it was a cultural landmark with no military significance, and that the bombing was indiscriminate and disproportionate.
Regardless, Dresden, along with Hiroshima and Nagasaki, have come to symbolize the awful development in 20th century warfare, wherein no distinction is made between civilians and soldiers.
This is just a small sampling; you can see many more of Gallup's photos at The Telegraph.
