He also was initially indecisive in his removal of Lloyd Fredendall, commanding U.S. II Corps. He became more adroit in such matters in later campaigns.[86] In February 1943, his authority was extended as commander of AFHQ across the Mediterranean basin to include the British Eighth Army, commanded by General Sir Bernard Montgomery. The Eighth Army had advanced across the Western Desert from the east and was ready for the start of the Tunisia Campaign. Eisenhower gained his fourth star and gave up command of ETOUSA to become commander of NATOUSA.
After the capitulation of Axis forces in North Africa, Eisenhower oversaw the invasion of Sicily. Once Mussolini, the Italian leader, had fallen in Italy, the Allies switched their attention to the mainland with Operation Avalanche. But while Eisenhower argued with President  Roosevelt and British Prime Minister Churchill, who both insisted on unconditional terms of surrender in exchange for helping the Italians, the Germans pursued an aggressive buildup of forces in the country. The Germans made the already tough battle more difficult by adding 19 divisions and initially outnumbering the Allied forces 2 to 1.
