Kämpfe was born in Thüringen, Germany in 1909. He trained to be a typographer like his father but after Hitler took power in 1933 he became a Leutnant in the Heer before transferring to the Waffen-SS in 1939. On the Eastern Front in Russia, he commanded the 3rd Battalion, 4th SS-Panzergrenadier Der Führer Regiment, the Das Reich Division's reconnaissance group. Kämpfe received the Knights Cross of the Iron Cross for bravery and exemplary leadership during the Zhitomir–Berdichev Offensive in the winter of 1943-44. In Spring 1944, the Das Reich Division had been withdrawn from Russia and sent to the south of France for refitting in preparation for the anticipated Allied invasion of occupied Europe. While in the southern France, Kämpfe was ordered to begin operations against the Maquis. On 9 June 1944, he was captured east of Saint-Léonard-de-Noblat by a group led by a Sergeant Jean Canou from Colonel Georges Guingouin's Brigade, a group in the Maquis du Limousin. Canou handed him over to Guingouin. The following day Kämpfe was executed on the orders of Guingouin or killed during an attempt to escape. His body was then burned. When it was discovered that the highly decorated officer had been kidnapped, troops from the Das Reich division and members of the Milice began a brutal search of the surrounding area for Kämpfe. Two local men were shot dead east of Saint-Léonard-de-Noblat. Later that day the massacre at Oradour-sur-Glane was committed by troops from the 1st Battalion, Das Reich. The commander of the 4th SSPanzer Grenadier Regiment, SS-StandartenführerSylvester Stadler ordered a court martial into the massacre at Oradour-sur-Glane. SS-SturmbannführerAdolf Diekmann, the commander of the 1st Battalion, 4th SS Panzer Grenadier Regiment, and a personal friend of Kämpfe, was charged over the killings. He said he found Kämpfe's handcuffed body inside a German field ambulance with the remains of other German soldiers just outside the village of Oradour-sur-Glane. The vehicle had been set alight burning alive everyone inside. After seeing his friend's fate, the village was destroyed on his orders. SS-BrigadeführerHeinz Lammerding, Das Reich's division commander, agreed that Diekmann should face a court martial. All charges were dropped when Diekmann was killed fighting in Normandy on June 29, 1944.
