The 13th Infantry Division "Re" () was an infantry division of the Royal Italian Army during World War II. The division was based in Friuli and entitled to the King ().
History
The division's lineage begins with the Brigade "Savoia" established in 1814, which on 25 October 1831 split to form the 1st and 2nd infantry regiments under the brigade's command. When the Second French Empire annexed Savoy on 14 June 1860 after the Second Italian War of Independence the brigade was renamed on the same day as "Brigade of the King" ().
World War I
The brigade fought on the Italian front in World War I. On 23 October 1926 the brigade assumed the name of XIII Infantry Brigade and received the 55th Infantry Regiment "Marche" from the disbanded Brigade "Marche". The brigade was the infantry component of the 13th Territorial Division of Udine, which also included the 15th Artillery Regiment. On 1 January 1928 the XIII Infantry Brigade exchanged the 55th Infantry Regiment "Marche" for the 56th Infantry Regiment "Marche" of the X Infantry Brigade. In 1934 the division changed its name to 13th Infantry Division "Montenero". On 22 February 1939 the division ceded the 56th Infantry Regiment "Marche" to the newly activated 32nd Infantry Division "Marche". On 15 May 1939 the division ceded the 15th Artillery Regiment to the newly activated 38th Infantry Division "Puglie". On the same day the division took its traditional name "Re", dissolved the XIII Infantry Brigade, with the two remaining infantry regiments coming under direct command of the division, and received the 34th Artillery Regiment from the 12th Infantry Division "Timavo".
World War II
Yugoslavia
Early in 1940 the division swapped artillery regiments with the 12th Infantry Division "Sassari". On 10 June 1940, the day Italy entered World War II, the Re was deployed along the border with Yugoslavia in the Cerkno – Idrija – Črni Vrh – Most na Soči area. The division remained in Friuli on border patrol duty until the invasion of Yugoslavia on 6 April 1941. On 6 April the Re crossed the border at Stregna. From 6–10 April 1941 the division defeated heavy resistance at Ravnik pri Hotedršici and then captured Ledine and Pečnik. On 11 April the Yugoslavian resistance collapsed and the division was able to capture Žiri and Goropeke. On 14 April 1941 the division entered Ljubljana.
Croatia
In May 1941 the division was transferred as occupation force to Croatia. Increasingly intensive battles with Yugoslav partisans were fought in November–December 1941 at Štirovača forest, Divoselo, and Žuta Lokva. Fighting occurred initially at Gospić, Otočac and Bihać. The partisans launched a major assault on Korenica and Udbina on 2–15 January 1942. These attacks were defeated by the Re, and in February–March 1942, the division participated in mopping-up operations in the area. Between 23 and 28 March 1942 the division tried to break through partisan lines to relieve the besieged garrisons in Titova Korenica, Udbina and Donji Lapac. The operation was successful and the division suffered only light casualties. Already in April 1942 the partisans went on the offensive again and launched an assault on Mogorić and Bihać. The partisan's strength was such, that he garrison of Bihać had to be evacuated in June 1942. By the end of June all lost positions had been recovered after fierce fighting.
While the Re was on occupation duty in Yugoslavia the division's regimental depots in Italy raised the 159th Infantry Division "Veneto": the depot of the 1st Infantry Regiment "Re" raised the 256th Infantry Regiment "Veneto", the depot of the 2nd Infantry Regiment "Re" raised the 255th Infantry Regiment "Veneto", and the depot of the 23rd Artillery Regiment "Re" raised the 159th Artillery Regiment "Veneto".
