Tietzen was born 19 July 1912 at Arnswalde (today Choszczno in Poland). As a Leutnant, Tietzen served with 3. Staffel of Jagdgruppe 88 of the Condor Legion during the Spanish Civil War. He claimed his first air victory on 19 July 1938, downing a Republican I-16. On 1 August, Tietzen made a forced landing 12 kilometers (7.5 miles) northeast of Gandesa.[1] He claimed a further six victories and was awarded the Spanienkreuz in Gold. On 1 November 1939, Tietzen was appointed Staffelkapitän (squadron leader) of the newly created 5. Staffel (5th squadron) of Jagdgeschwader 51 (JG 51—51st Fighter Wing).[2] The Staffel had been created in August 1939 as the Reservestaffel (reserve squadron) of Jagdgeschwader 71 (JG 71—71st Fighter Wing).[3]
He shot down a French Bloch MB.174 bomber for his first victory of World War II on 20 April 1940. He recorded his 17th victory on 25 July 1940, a Spitfire near Dover. On 15 August Tietzen shot down three Hurricanes. He became the fourth German fighter pilot to record 20 victories on 18 August. However, on the same day, he was shot down in aerial combat with Royal Air Force Hurricane fighters over the Thames Estuary.[4] His victors were Flying Officer Stefan Witorzenc and Pilot Officer Pawel Zenker from No. 501 Squadron who reported two Messerschmitt Bf 109 fighters shot down between Canterbury and Westgate-on-Sea which crashed near the North Goodwin Lightship. His body later washed ashore at Calais in France. Tietzen now rests at the Bourdon German war cemetery.[5] He was posthumously awarded the Knight's Cross of the Iron Cross (Ritterkreuz des Eisernen Kreuzes) on 20 August 1940.[6]
