Quite literally the first paragraph of the article:
According to Soviet records 381,067 German Wehrmacht POWs died in NKVD camps (356,700 German nationals and 24,367 from other nations).
Or in more detail lower down in the section titled Soviet statistics:
According to Russian historian Grigori F. Krivosheev, Soviet NKVD figures list 2,733,739 German “Wehrmacht” POWs (Военнопленные из войск вермахта) taken with 381,067 having died in captivity.
So much more. It’s not even in the same ballpark.
