Born on September 7, 1920 in Billerbeck, Germany, Paul-Georg Kleffel's early life isn't much known and in fact, much of what we do know concerns his military career. In 1939, Kleffel joined the German Heer (Army), his qualifications permitting him to apply from the outset as a reserve officer (Reserveoffiziere). He was sent to one of the five Kriegsschulen (War Schools) within Germany to attend the standard eight week training course which Kleffel successfully passed, graduating with the rank of Leutnant der Reserve (2nd. Lieutenant) sometime in 1941.
Kleffel was posted to the 4./Panzer-Aufklärungs-Abteilung 3 (4th. Company, 3rd. Reconnaissance Detachment) which was part of the 3. Panzerdivision. The division was the third of the original three panzer divisions created by the German Army, being formed on October 15, 1935. The 3. Panzerdivision saw action during the invasion of Poland, combat in Belgium, and saw action during the Battle of France. Kleffel, however, did not go into battle with the division until Unternehmen Barbarossa (Operation Barbarossa), the invasion of Russia, that kicked off on June 22, 1941. 3. Panzerdivision was under the XXIV. Armeekorps as part of the 2. Panzerarmee which itself was under Heeresgruppe Mitte (Army Group Center).
Kleffel remained with the 4./Panzer-Aufklärungs-Abteilung 3 for the entirety of the war but curiously, much of his early combat career on the Eastern Front isn't well documented. In fact, the two volume series “Armored Bears: The German 3rd. Panzer Division in World War II”, written by veterans of the 3rd. Panzer Division, makes no mention of Kleffel until his actions in 1943-1944. What we do know is that his first position in the 4th. Kompanie was as a Zugführer (platoon leader). It was during this time that Kleffel was decorated with the Eisernes Kreuz 2. Klasse (Iron Cross 2nd. Class), Eisernes Kreuz 1. Klasse (Iron Cross 1st. Class), Nahkampfspange in Bronze (Close Combat Clasp in Bronze), and the Medaille Winterschlacht im Osten 1941/42 (Winter Battle in the East 1941–42 Medal) which is more often referred to as the Ostmedaille (Eastern Medal). The latter, a campaign medal, was received for service in Russia between November 15, 1941 and April 15, 1942. On November 16, 1943, Kleffel (now a Oberleutnant der Reserve;1st. Lieutenant) was awarded with the Deutsches Kreuz in Gold (German Cross). This decoration was received for either repeated acts of bravery under fire or for examples of exceptional military leadership. A part of the prerequisite to being awarded this medal was to already have earned the Eisernes Kreuz 1. Klasse which Kleffel had.
On April l13, 1944, now Kompaniechef (Company Commander) of the 4th. Kompanie, Kleffel and his unit was situated in a wooded area to the east of Orhei (today in the Republic of Moldova). There, they spotted Soviet infantrymen advancing through the woods and Kleffel understood that if the Soviets were allowed to establish themselves there, it would pose a very real threat to the German defensive lines to the south of Orhei. Without orders, Kleffel moved to attack, committing eight Schützenpanzerwagen (SPW), the term German officers used for the Sonderkraftfahrzeug 251 (Sd.Kfz 251) half-track. As the half-tracks crested a hill, Soviet anti-tank guns greeted them but skillful use of the terrain and mobility of the half-tracks allowed Kleffel to maneuver to the flank of the Soviet infantry where the machine-guns tore into the Soviet troops, sending them into a panic. Not one to pause, Kleffel pushed the attack against the routed infantry, chasing them despite driving into the effective range of the Soviet guns. The Soviet troops, part of a regiment, were decimated but before the Soviets could mobilize a counter-attack, Kleffel pulled his half-tracks back to his line. For this action, Kleffel was presented with the Ritterkreuz des Eisernen Kreuzes (Knight's Cross of the Iron Cross) on May 14, 1944. Kleffel, during his combat career, was wounded seven times though interestingly, his known decorations do not include the Verwundetenabzeichen (Wound Badge). Even if the injuries were relatively minor, it would have certainly been enough to warrant the Verwundetenabzeichen 3. Klass. In addition, sometime in the latter half of 1944, Kleffel was promoted to Hauptmann (Captain).
Kleffel survived the war but whether he served any time as a POW is not known. He finished an apprenticeship and starting in 1949, he worked in the film industry until 1956 when he joined the Bundeswehr. Entering into service as a Hauptmann, in keeping with his rank from World War Two, Kleffel completed his general staff training and became the G3 (operations) staff officer for Panzergrenadierbrigade 13 from 1959 to 1963. He then spent a year at the Führungsakademie der Bundeswehr (Bundeswehr Leadership Academy) until 1964 when he transferred to, interestingly, the 3. Panzerdivision as their Chief of Staff. Promoted to Oberst (Colonel), Kleffel became a planner in 1968 at the Bundesministerium der Verteidigung (Federal Ministry of Defense) until taking over as the commander of Panzergrenadierbrigade 16 whose command he held until April 30, 1972. Following that command, Kleffel moved to lead the III. Korps until September 1973 when he then assumed command of the 12. Panzerdivision until September 30, 1976. Kleffel would hold several other positions until he retired from the Bundeswehr on September 30, 1980. Bundeswehr decorations he received included the Verdienstkreuz 1. Klasse (Cross of Merit 1st. Class) in 1973 and the Großes Verdienstkreuz (Commander's Great Cross of Merit) in 1979.
After retiring, Kleffel became the manager for Johanniter-Unfall-Hilfe (Johanniter Accident Aid), a Christian charity organization. He remained as manager until 1987. Paul-Georg Kleffel died in Bonn, Germany on February 19, 2020 at the age of 99.
The photograph here is likely a postwar autograph card. It shows Kleffel as a fresh Leutant der Reserve as denoted by his schulterstücke (shoulder boards) and he is wearing the Dienstanzug für Offiziere (Service Uniform for Officers) in the Modell 1936 style, evidenced by the dark, blue-green collar. That is could be postwar is that the photograph is cropped in such a way as to not show the swastika of the adler (eagle) above the right breast pocket. The display of the swastika in Germany was banned following the approval of Strafgesetzbuch (Criminal Code), Section § 86a in the 1950s.
