"The strangest battle in the entire recent history of wars" (Clausewitz) crowned the next year of the Seven Years War (1756-1763). And in the Berlin archive, about a hundred letters from officers of the Russian-Imperial Army, intercepted by the Prussians after the Battle of Zorndorf, are accidentally discovered. Will they shed new light on the history of what happened, what answers do they give and do they give at all? Or is it worth asking them other questions?
