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 First Army 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. Background The U.S. II Corps had been badly mauled in its first encounter with Axis forces in Tunisia during a series of battles that culminated in the disastrous Battle of the Kasserine Pass in late February 1943. Erwin Rommel—poised on the threshold of a complete tactical victory—turned from the battle to return to his eastward-facing defenses at the Mareth Line when he heard of the approach of Bernard Montgomery′s British 8th Army. Thus the battle concluded with the U.S. forces still in the field, but having lost ground and men, and with little confidence in some key commanders. In the last week of January 1943, despite a massive artillery bombardment, the Italian 14th Bersaglieri Battalion of the 131st Armoured Division Centauro dug in near Djebel Rihana. Harold V. Boyle, an Irish war correspondent, wrote that a second attack was required using grenades and bayonets in order to evict the Italians: Artillery and aircraft may harass but cannot dislodge him. Only bullets and bayonets of rival riflemen can do that. This was well illustrated in the Ousseltia Valley campaign in January when tanks and artillery laid down one of the finest barrages of the campaign but couldn't rout Italians dug in like moles in the hills bordering the road to Kairouan. The artillery was beautiful to see but they couldn't do the job alone. Finally American infantry swarmed up the hills at night and flushed the Italians out in droves with hand grenades and the pointed persuasion of their bayonets. The American command reacted to its reverses against German and Italian forces with a prompt and sweeping series of changes in command, discipline, and tactics. Also, large units were kept massed rather than being broken up into smaller, unsupported elements as had been done under U.S. II Corps Commander Lloyd Fredendall. Close air support was also improved. On 6 March 1943, George Patton took command of the U.S. II Corps from Lloyd
