Photograph of a Soviet soldier prior to the Battle of Kursk, 1943. This photograph is really remarkable in that it shows a soldier in the Red Army making a visible religious devotion in a state that didn't approve of that. Given the style of the cross, he was likely Catholic and probably Polish or Ukrainian.
I'm sure that this day will go largely unnoticed and unobserved. I'm only aware of it due to Kursk. Perhaps its a day that can serve for meaning more than its intended to mean.
