総統大本営
On 5 August 1939, Wick married Ursel Rolfs (1916–1968) in Berlin. The marriage produced two children, Walter (born in October 1939) and a girl, Sabine, born after Wick's death, in February 1941. On 23 January 1941, Wick's father received a telephone call from Bodenschatz at the Führer Headquarters that Wick had been rescued and taken prisoner of war. Apparently an official Reuters report had indicated that a 25-year-old Luftwaffe "Major", credited with 56 aerial victories, had been interned in a prisoner-of-war camp in Canada. Both Hitler and Göring initiated steps to get confirmation of the report. On 5 February 1941, a telegram from Ottawa informed Ursel that Wick was not interned in Canada. Ursel married the military doctor, "Stabsarzt" (equivalent to captain) Dr. Gerhard Tausch, later in the war.
