Osprey's survey of the recipients of the Knight's Cross and Oak-Leaves andnbsp;Swordsnbsp;awards during World War II (1939-1945). On 21 June 1941, as the Wehrmachtstormed forward across the frontiers of the Soviet Union, Hitler instituted a new higher grade of the Knight's Cross decoration for gallantry and leadership: the silver clasp of the Oak-Leaves with Swords. It would be awarded to only 159 men of the approximately 15 million who served in the German armed forces during World War II. This third in a sequence of four titles describes and illustrates a selection of the recipients: from much-wounded front line infantry officers, to Hitler's 'brother-in-law'; from a sergeant pilot fighter ace, to the commanding general of the greatest tank force ever gathered on the Russian Front.
