After World War II, Schmidt became a writer. Aided by the network of 'old comrades' working in the publishing industry, he was able to secure assignments. Starting in the 1950s, he wrote for the popular magazine
Kristall. He first used the pseudonym
Paul Karell, and later
Paul Carell. Carell was a member of the
Naumann Circle, a group of Neo-Nazis who sought to infiltrate the
Free Democratic Party. He worked as a freelance author under various noms de plume for newspapers such as
Die Welt and
Die Zeit (as P. C. Holm, among others). He also wrote for the magazines
Norddeutsche Rundschau and
Der Spiegel, and published some accounts of war stories for
Der Landser, a West German
pulp magazine featuring stories predominantly set during World War II. He was seen as an influential adviser to the German
Axel Springer AG, where he wrote speeches for
Axel Springer. From 1965 to 1971, the
Office of the State Prosecutor of
Verden in Germany investigated him for
murder. But the investigation, which should have clarified his role in the
genocide of Hungarian Jews, ended without an indictment. Schmidt never had to face a trial for his activities during the war. In 1992, Carell claimed that even after the
Battle of Stalingrad, there was a possibility for Germany to win the war. In his view, it was primarily the command of
Adolf Hitler that led to the defeat. The leadership of the
Wehrmacht and very competent commanders such as
Erich von Manstein could have achieved victory if not for Hitler's interference. Carell also claimed that the invasion of the Soviet Union was a
preemptive attack to forestall an invasion of Germany by the
Red Army. ==Writing career==
