Short answers, pulled from the story.
Rommel earned the nickname "Desert Fox" (der Wüstenfuchs) during his command of the Afrika Korps in the North African campaign from 1941 onward. Both Allied and German reporting used the name to describe his elusive, fast-moving tactics in the Western Desert. He used sandstorms, darkness, and rapid manoeuvre to unsettle the enemy and often directed operations from the front or flew over the battlefield himself.
Rommel was implicated in the 20th of July 1944 plot to assassinate Hitler after wounded conspirators named him under interrogation. On the 14th of October 1944, two generals from Hitler's headquarters visited his home and offered him a choice between suicide and facing the People's Court. He chose suicide, taking a cyanide capsule in a staff car near his home. The Nazi government publicly announced he had died from complications of wounds sustained in Normandy, and he was given a state funeral in Ulm.
Rommel's precise involvement is disputed because most conspirators were killed and documentation is fragmentary. Papers discovered in 2018 include accounts of meetings between Rommel and resistance members in May 1944, and Stuttgart mayor Karl Strölin stated postwar that Rommel agreed in February 1944 to support the resistance. Rommel initially opposed assassination in favour of arrest and trial. On the 15th of July 1944 he wrote Hitler a letter urging him to "draw the proper conclusions without delay" about ending the war.
Rommel's most significant victories included the capture of around 9,000 prisoners and 81 guns with only 150 men at the Battle of Caporetto in October 1917, the rapid advance of his 7th Panzer Division through France in 1940 that yielded over 100,000 prisoners, and the fall of Tobruk in June 1942 in which around 32,000 Commonwealth troops were captured. His last significant battlefield victory was the Battle of Kasserine Pass in February 1943 against the US II Corps.
Hitler promoted Rommel to Generalfeldmarschall on the 22nd of June 1942, following the capture of Tobruk in which around 32,000 Commonwealth troops surrendered along with substantial supplies and the port itself. It was one of the largest single captures of British Commonwealth forces in the war, second only to the fall of Singapore earlier that year. The promotion came ahead of many senior officers and reflected Hitler's personal favour as well as the scale of the victory.
Historians give varied assessments. Rommel did not pass Hitler's Commando Order to his subordinates, and his units reportedly treated captured Allied commandos as regular prisoners of war. His 7th Panzer Division operated in areas of France where massacres of black French prisoners of war were frequent, though no direct evidence implicates Rommel personally in ordering or condoning them. Orders he and Kesselring signed during the disarmament of Italian forces in 1943 have been criticised for contributing to brutal treatment, though historians disagree over the extent of his responsibility.
