World War I

The brigade fought on the Italian front in World War I. On 31 October 1926 the brigade assumed the name of XXX Infantry Brigade and received the 59th Infantry Regiment "Calabria" from the disbanded Brigade "Calabria". The brigade was the infantry component of the 30th Territorial Division of Cagliari, which also included the 16th Artillery Regiment. In 1934 the division changed its name to Military Command Cagliari - 30th Infantry Division "Sabauda" and in September of the same year the division ceded the 45th Infantry Regiment "Reggio" and 59th Infantry Regiment "Calabria" to the newly activated XXXI Infantry Brigade, which was part of the newly formed Military Command Sassari - 31st Infantry Division "Caprera".^[1][4][5][6]

On 1 May 1935 the Military Command Cagliari raised the 60th Infantry Regiment "Calabria" in Iglesias, which in June of the same year entered the XXX Infantry Brigade.^[1]

Second Italo-Ethiopian War

In 1935 the Sabauda was mobilized for the Second Italo-Ethiopian War. The division arrived in Massawa in Eritrea on 21 June 1935 and consisted of the 46th and 60th infantry regiments, and the 16th Artillery Regiment. the 3rd Bersaglieri Regiment was attached to the division for the duration of the campaign. Initially the Sabauda division was tasked with the border defence duties in Asmara-Dek’emhāre area. At the outbreak of the war on 3 October 1935 the division held a defensive line near Barachit and after overcoming initial Ethiopian resistance at Fik’ada (Focada) it advanced rapidly into Ethiopian territory. In November 1935 the Sabauda took Negash, Agula and Bolbala and then moved to positions on the heights overlooking the Tekezé during the Ethiopian Christmas Offensive. The division resumed its advance on 6 January 1936 only to stop for all of February 1936 in Enderta Province. The Sabauda had a minor role in the Battle of Amba Aradam on 13–27 February 1936. On 3 April 1936 the division arrived at Amba Alagi, where it won a decisive encounter and pursued the retreating Ethiopians to Agumserta and finally to Lake Ashenge. With the way to Addis Ababa open, the division surged forward, reaching Shewa Kifle Hāger village on the capital's outskirts on 26 April 1936, and captured Addis Ababa itself on 5 May 1936. The division remained in the capital until December 1936, when it returned to Sardinia.^[1]

World War II

In early 1939 the 45th Infantry Regiment "Reggio" in Sassari and the 60th Infantry Regiment "Calabria" in Iglesias switched names and on 15 April 1939 the Sabauda dissolved the XXX Infantry Brigade, with the two infantry regiments coming under direct command of the division. On the same date the 16th Artillery Regiment received the name "Sabauda". The division was tasked with the defence of southern Sardinia, as part of the XIII Army Corps.^[1]

In June 1940 the division's sector was reduced to the area of Sulcis, where a allied landing was deemed most likely. In December 1941 the 205th Coastal Division was activated in Carbonia, which took up the coastal defense duty, with the Sabauda tasked as mobile reserve behind the 205th Coastal Division. The Sabauda remained at its positions until the Armistice of Cassibile was announced on 8 September 1943. On 10 September 1943 the division repositioned itself northwards along the Villacidro-Samassi-Selegas-Suelli line to deflect an expected attack by the German 90th Panzergrenadier Division. However the Wehrmacht decided to evacuate its forces to Corsica and the Italian units on Sardinia allowed them to withdraw unhindered.^[1]

After Sardinia was secured the Sabauda moved to Sicily on 10 November 1943, where it initially took up positions in the Enna-Caltanissetta region, until it relocated to the Messina-Catania-Syracuse area in September 1944. On 1 October 1944 the division was reformed as Internal Security Division "Sabauda" and for the rest of the war engaged primarily in airfield defence, policing and demining work.^[1]

Infantry Brigade "Reggio"

On 15 August 1946 the Internal Security Division "Sabauda" was downsized to brigade and, due to the result of the 1946 Italian institutional referendum, which had resulted in the deposition of the Royal House of Savoy, the brigade was named Infantry Brigade "Reggio". The Reggio was dissolved with most of its units on 1 Februar 1948, while the 46th Infantry Regiment "Reggio" joined the Infantry Division "Aosta".
