World War II

On 7 April 1944, Zimmermann was appointed Staffelkapitän (squadron leader) of 6. Staffel of JG 3. He replaced Hauptmann Heinrich Sannemann who was transferred and led the Staffel until late April when Zimmermann took command.^[1] On 19 May, Zimmermann and his wingman had a mid-air collision. Both pilots bailed out and were unhurt, their Messerschmitt Bf 109 aircraft crashed southeast of Wittenberge.^[2]

In July, Zimmermann was transferred again and appointed Staffelkapitän of 9. Staffel of JG 3. He succeeded Leutnant Dieter Zink who had been shot down by anti-aircraft artillery and taken prisoner of war on 11 July.^[3] Zimmermann was awarded the Knight's Cross of the Iron Cross (Ritterkreuz des Eisernen Kreuzes) on 29 October for 28 aerial victories claimed.^[4] On 18 December during the Battle of the Bulge, Zimmermann claimed his 29th aerial victory when he shot down a Republic P-47 Thunderbolt fighter.^[5] On 1 January 1945 during Operation Bodenplatte, Zimmermann claimed a Hawker Tempest shot down.^[6]

Later life

Zimmermann died on 12 February 1976 at the age of 58 in Bad Hersfeld, West Germany.^[7]

Summary of career

Aerial victory claims

According to Obermaier, Zimmermann was credited with 34 victories in over 580 combat missions, 28 of which claimed on the Western Front including 14 heavy bombers.^[8] Mathews and Foreman, authors of Luftwaffe Aces — Biographies and Victory Claims, researched the German Federal Archives and state that he was credited with at least 28 aerial victories, plus two further unconfirmed claims. Of this figure, he claimed six aerial victories on the Eastern Front and more than 22 over the Western Allies, including eleven four-engined heavy bombers.^[9]

Victory claims were logged to a map-reference (PQ = Planquadrat), for example "PQ 46264". The Luftwaffe grid map (Jägermeldenetz) covered all of Europe, western Russia and North Africa and was composed of rectangles measuring 15 minutes of latitude by 30 minutes of longitude, an area of about 360 square miles (930 km²). These sectors were then subdivided into 36 smaller units to give a location area 3 km × 4 km (1.9 mi × 2.5 mi) in size.^[10]

Chronicle of aerial victories
This along with the * (asterisk) indicates an Herausschuss (separation shot)—a severely damaged heavy bomber forced to separate from his combat box which was counted as an aerial victory.   This and the ? (question mark) indicates information discrepancies listed by Prien, Stemmer, Rodeike, Bock, Mathews and Foreman.
