Anyway, I made my way to this because I saw Robert Capa's brother Cornell listed in the current issue of AP, and remembered that Robert had taken some photos during the war, so I set off to find them on Magnum Photos . These photos aren't all his, and also include work from others from the same time. I'll be sharing more soon!
Click on each photo to be taken to them on the website where there's a bit more of a description that what I'm giving here, as well as around 1000 more photos from this time.
