Hasso Eccard von Manteuffel (14 January 1897 – 24 September 1978) was a German general during World War II who commanded the 5th Panzer Army. He was a recipient of the Knight’s Cross of the Iron Cross with Oak Leaves, Swords and Diamonds of Nazi Germany.
During Operation Barbarossa, the invasion of the Soviet Union, Manteuffel commanded a battalion in the 7th Panzer Division, in the Army Group Centre.
In early 1943, Manteuffel was sent to Africa, where on 5 February he became the commander of the Division von Broich/von Manteuffel, serving in 5th Panzer Army. Here Manteuffel took part in the Battle of Tunisia. Manteuffel assumed command of the 7th Panzer Division on 22 August 1943 and was posted to the Eastern Front, which had by then collapsed following the Battle of Kursk and the resulting Soviet counteroffensive. The division retreated during the resulting Battle of the Dnieper.
Manteuffel was appointed commander of the Grossdeutschland Division on 1 February 1944. The division engaged the Red Army west of Kirovograd, then retreated across Ukraine. In late July Großdeutschland was ordered to East Prussia, following the collapse of Army Group Centre in Soviet Operation Bagration. The division failed to break through to the Army Group North in the Courland Pocket.
On 1 September 1944, Manteuffel was promoted to General of Panzer Troops and given command of the 5th Panzer Army on the Western Front, which took part in the Ardennes Offensive. Manteuffel’s 5th Panzer Army achieved one of the deepest penetrations of Allied lines during the offensive, almost reaching the Meuse River, and engaging the U.S. forces at the Battle of Bastogne. On 10 March 1945 Manteuffel was made the commander of the 3rd Panzer Army on the Eastern Front, attached to Army Group Vistula. His army was assigned to defend the banks of the Oder River north of the Seelow Heights. On 25 April the Soviet 2nd Belorussian Front broke through Third Panzer Army’s line, forcing a German retreat. On 3 May 1945 Manteuffel surrendered his troops to the British Army at Hagenow, Germany. (Source: Wikipedia)
