The Germans did not achieve surprise and were not able to outflank or break through into enemy rear areas during the operation. Several historians assert that Operation Citadel was planned and intended to be a blitzkrieg operation. Many of the German participants who wrote about the operation after the war, including Manstein, make no mention of blitzkrieg in their accounts. In 2000, Niklas Zetterling and Anders Frankson characterised only the southern pincer of the German offensive as a "classical blitzkrieg attack". Pier Battistelli wrote that the operational planning marked a change in German offensive thinking away from blitzkrieg and that more priority was given to brute force and fire power than to speed and manoeuvre.
