The Battle of Sidi Bou Zid (Unternehmen Frhlingswind/Operation Spring Breeze) took place during the Tunisia Campaign from 1417 February 1943, in World War II. The battle was fought around Sidi Bou Zid, where a large number of US Army units were mauled by German and Italian forces. It resulted in the Axis forces recapturing the strategically important town of Sbeitla in central Tunisia.

The battle was planned by the Germans to be a two-part offensive-defensive operation against US positions in western Tunisia. Generaloberst Hans-Jrgen von Arnim commanded several experienced combat units, including the 10th Panzer Division and the 21st Panzer Division of the 5th Panzer Army, which were to sweep north and west towards the Kasserine Pass, while another battle group attacked Sidi Bou Zid from the south. Facing the attack was the II US Corps under Major General Lloyd Fredendall.

In a few days, the Axis attack forced the II US Corps to take up new defensive positions outside Sbiba. Axis troops were then given time to consolidate their new front line west of Sbeitla. The success of the offensive led the German High Command to conclude that despite being well equipped, American forces were no match for experienced Axis combat troops.

The Tunisian campaign (also known as the Battle of Tunisia) was a series of battles that took place in Tunisia during the North African campaign of the Second World War, between Axis and Allied forces from 17 November 1942 to 13 May 1943. The Allies consisted of British Imperial Forces, including a Greek contingent, with American and French corps. The battle opened with initial success by the German and Italian forces but the massive supply interdiction efforts led to the decisive defeat of the Axis. Over 250,000 German and Italian troops were taken as prisoners of war, including most of the Afrika Korps.
