Aspects of the event
Operation Ochsenkopf, a multi-pronged attack on the Allied supply lines in northern Tunisia, was launched on 26 February 1943. Rommel had been given command of all Axis forces in Africa on the 23rd, and so this operation was the only one where Tiger tanks fell under his authority; but since he was busy in the south, Ochsenkopf was very much the creation of von Arnim, the man who had refused to lend his Tigers to Rommel's Kasserine Pass battle.
The main component of this operation was Kampfgruppe Lang, a battle group tasked with capturing Beja. If they could take that town, they would stand between the Allied armies and their ports. This group included 14 Tigers, all that were functional at the time in Africa. The battle group started from south of Mateur and entered the Hunt's Gap valley in the morning, only to be halted at the battle of Sidi N'sir.
The battle group was confined to the road and extended for several kilometers. Most of it was not involved in the battle and did not descend to the valley floor until the following day. A German propaganda team took photos of the vehicles on the road to Sidi N'sir, during and after the battle.
