The last Rommel offensive in North Africa was on 6 March 1943, when he attacked Eighth Army at the Battle of Medenine. The attack was made with 10th, 15th, and 21st Panzer Divisions. Alerted by Ultra intercepts, Montgomery deployed large numbers of anti-tank guns in the path of the offensive. After losing 52 tanks, Rommel called off the assault. On 9 March he returned to Germany. Command was handed over to General Hans-Jürgen von Arnim. Rommel never returned to Africa. The fighting there continued on for another two months, until 13 May 1943, when General Messe surrendered the "Armeegruppe Afrika" to the Allies.
