Sedjenane is a town in northern Tunisia, on the railway line to Mateur and the port of Bizerta.

The Battle of Kasserine Pass was a battle of the Tunisia Campaign of World War II that took place in February 1943.
 Kasserine Pass is a 2 mi gap in the Grand Dorsal chain of the Atlas Mountains in west central Tunisia.
 The Axis forces, led by "Generalfeldmarschall" Erwin Rommel, were primarily from the "Afrika Korps" Assault Group, elements of the Italian "Centauro" Armoured Division and two Panzer divisions detached from the 5th Panzer Army, while the Allied forces consisted of the U.S. II Corps (Major General Lloyd Fredendall), the British 6th Armoured Division (Major-General Charles Keightley) and other parts of the First Army (Lieutenant-General Kenneth Anderson).
Unternehmen Ochsenkopf (Operation Ox Head) also known as the Battle of Sidi Nsir, and the Battle of Hunts Gap was an Axis offensive operation in Tunisia from 26 February – 4 March 1943, during the Tunisia Campaign of the Second World War.
 The offensive and a subsidiary operation "Unternehmen Ausladung", was intended to gain control of Medjez el Bab, Béja, El Aroussa, Djebel Abiod and a position known as Hunt's Gap, between the British First Army and the Axis Army Group Africa ("Heeresgruppe Afrika" /"Gruppo d'Armate Africa" ).
 The offensive gained some ground but none of the more ambitious objectives were reached before the operation was called off, due to increasing losses of infantry and tanks, particularly the heavy Tigers.
 "Unternehmen Ochsenkopf" was the last big Axis offensive by the 5th Panzer Army before the final Allied offensive in April and May, which occupied Tunisia and took the surviving 250,000 Axis troops into captivity.
Lieutenant General Lloyd Ralston Fredendall (December 28, 1883 – October 4, 1963) was a senior officer of the United States Army who fought during World War II.
 He is best known for his command of the Central Task Force landings during Operation Torch, and his command of the II Corps during the early stages of the Tunisian Campaign.
 In February 1943, while in command of the II Corps, his forces were defeated by German forces commanded by "Generalfeldmarschall" Erwin Rommel and "Generaloberst" Hans-Jürgen von Arnim in the Battle of Kasserine Pass.
 After this setback, Fredendall was relieved of command of II Corps by General Dwight D. Eisenhower, the Supreme Allied Commander in North Africa, and replaced by Major General George S. Patton Jr. in March 1943.
 In spite of his relief, Fredendall was promoted to lieutenant general in June 1943, assumed command of the Second Army and was greeted back home in the United States as a hero.

 The battle was for control over the key strategic height Hill 609 and its surrounding area between the American forces of the U.S. II Corps and German units of the Afrika Korps.
 The battle proved a formative experience for the American forces - it their first clear cut victory of the campaign and has been called "the American Army's coming-of-age".
The Battle of El Guettar was a battle that took place during the Tunisia Campaign of World War II, fought between elements of the Army Group Africa under General Hans-Jürgen von Arnim, along with Italian forces under General Giovanni Messe, and U.S. II Corps under Lieutenant General George Patton in south-central Tunisia.
 It was the first battle in which U.S. forces were able to defeat the experienced German tank units, but the followup to the battle was inconclusive.

 The battle was fought around Sidi Bou Zid, where a large number of American units were mauled by German and Italian forces.
 It resulted in the Axis recapturing the strategically important town of Sbeitla in central Tunisia.
 The success at Sidi Bou Zid was reversed by April by counter-attacks by British and American forces.
 The battle was planned by the Germans to be a two-part offensive-defensive operation against US positions in western Tunisia.
Operation Vulcan was the final ground attack by the Allied forces against the Italian and German forces in Tunis, Cap Bon, and Bizerte, Tunisia, the last Axis toeholds in North Africa, during the Tunisia Campaign of the Second World War. "

 His advice was rejected by Hitler.
The Battle of Wadi Akarit (Operation Scipio) was an Allied attack from 6–7 April 1943, to dislodge Axis forces from positions along the Wadi Akarit in Tunisia (also known as the Akarit Line) during the Tunisia Campaign of the Second World War.
 The Gabès Gap, north of the towns of Gabès and El Hamma, is a passage between the sea and impassable salt marshes.
 The 51st (Highland) Infantry Division breached the defences and held a bridgehead, allowing the passage of their main force to roll up the Axis defences.
 After several determined counter-attacks, the Axis forces withdrew and the Eighth Army, under General Bernard Montgomery, pursued toward Tunis, until reaching Axis defensive positions at Enfidaville.
The Battle of El Agheila was a brief engagement of the Western Desert Campaign of the Second World War.
 It took place in December 1942 between Allied forces of the Eighth Army (General Bernard Montgomery) and the Axis forces of the German-Italian "Panzer" Army ("Generalfeldmarschall" Erwin Rommel), during the long Axis withdrawal from El Alamein to Tunis.
 It ended with the German-Italian "Panzer" Army resuming its retreat towards Tunisia, where the Tunisia Campaign had begun with Operation Torch (8–16 November 1942).
