8 March to 23 March: Benito Mussolini decided that Fascist Italian forces should lead a fourth offensive on Madrid. This Italian offensive resulted in the Battle of Guadalajara, which ended as a decisive victory for the Republican forces. In contrast, the Italian forces suffered heavy losses. The Italian armor, consisting for the most part of &lt;a href="L3/35"&gt;L3/35 tankettes&lt;/a&gt;, proved to be no match for the tanks provided to the Republicans by the Soviet Union. The Italian offensive was repulsed by a strong Republican counter-offensive led by the 11th Division. Of the four Italian divisions engaged, only the Littorio Division did not suffer heavy losses. The three CCNN divisions had such heavy losses that they had to be reorganized into two divisions and a special weapons (armour and artillery) group. The 3rd CCNN Division was disbanded and consolidated with the 2nd CCNN Division in April 1937.
