What is "nickforce"

Nickforce was an improvised formation of the British First Army in the Tunisia Campaign during World War II. It was hastily formed from elements of the British 6th Armoured Division on 14 February 1943, for the defence of Thala, during the latter stages of the Battle of the Kasserine Pass. It took its name from the commanding officer, Brigadier Cameron Nicholson. In desperate fighting, the force successfully blocked a Kampfgruppe of 10th Panzer Division, under the direct control of Erwin Rommel, on 21 and 22 February.
