15th Infantry Division "Bergamo"

The 15th Infantry Division "Bergamo" (15ª Divisione di fanteria "Bergamo") was an infantry division of the Royal Italian Army during World War II. The Bergamo was based in Istria and named for the city of Bergamo.

History
After the Second Italian War of Independence the Austrian Empire had to cede the Lombardy region of the Kingdom of Lombardy–Venetia to the Kingdom of Sardinia. After taking control of the region the government of Sardinian ordered the Royal Sardinian Army on 29 August 1859 to raise five infantry brigades and one grenadier brigade in Lombardy. Subsequently on 1 November 1859 the Brigade "Bergamo" was activated with the newly raised 25th and 26th infantry regiments.

World War I
The brigade fought on the Italian front in World War I. On 20 October 1926 the brigade command and the 25th Infantry Regiment were disbanded, while the 26th Infantry Regiment was transferred to the XV Infantry Brigade. The XV Infantry Brigade, which also included the 73rd Infantry Regiment "Lombardia" and the 74th Infantry Regiment "Lombardia", was the infantry component of the 15th Territorial Division of Pola, which also included the 4th Artillery Regiment. On 25 January 1930 the division moved to Volosko and consequently changed its name to 15th Territorial Division of Volosca. On 24 March 1932 the division moved to Opatija and changed its name to 15th Territorial Division of Abbazia. In 1934 the division changed its name to 15th Infantry Division "Carnaro".

On 24 May 1939 the 73rd Infantry Regiment "Lombardia" in Rijeka changed its name to 25th Infantry Regiment "Bergamo", while the 12th Infantry Regiment "Casale" of the 12th Infantry Division "Sassari" in Trieste changed its name to 73rd Infantry Regiment "Lombardia". The same day the division ceded the 74th Infantry Regiment "Lombardia" to the newly activated 57th Infantry Division "Lombardia" and changed its name to 15th Infantry Division "Bergamo". Also on the same day the VX Infantry Brigade was dissolved, with the 25th and 26th infantry regiments coming under direct command of the division, while the 4th Artillery Regiment received the name "Bergamo".

World War II
On 10 June 1940, the day Italy entered World War II, the Bergamo was deployed along the border with Yugoslavia in the Rijeka-Brešca-Klana sector. The division remained in the area on border patrol duty until the invasion of Yugoslavia on 6 April 1941. The Bergamo crossed the border on 6 April and on 11 April it broke through Yugoslavian defences on the Veli Vrh summit near Drenova and captured Kastav hill the same day. On 12 April it reached Bakar and continued to advance South along the Dalmatian coast. On 16 April 1941 the Bergamo captured Žuta Lokva village. After Yugoslavia's surrender the division was stationed in Dalmatia and garrisoned Makarska, Livno, Sinj, Ljubuški, Imotski and the island of Brač.

From 22–25 July 1941 the Bergamo fought Yugoslav partisans near Drvar. Another surge of fighting with Yugoslav partisans entering the Independent State of Croatia occurred from 9 October to 9 November 1941. Afterwards the main duties of the Bergamo were coastal defence, road protection and peacekeeping among the local communities. In June 1942 the division suppressed a major partisan revolt in the Lika region. The Bergamo took part in the anti-partisan Operation Alba in Croatia from 12 August to 2 September 1942. The aim of Operation Alba was to destroy partisan groups in the Biokovo area 40-50 kilometres east of Split. Italian forces burned down ten villages and killed and arrested several hundred people. In 1943 the division was garrisoned in Split and increasingly bloody skirmishes with partisans were fought.

While the Bergamo was on occupation duty in Yugoslavia the division's regimental depots in Italy raised the 156th Infantry Division "Vicenza": the depot of the 25th Infantry Regiment "Bergamo" raised the 277th Infantry Regiment "Vicenza", the depot of the 26th Infantry Regiment "Bergamo" raised the 278th Infantry Regiment "Vicenza", and the depot of the 4th Artillery Regiment "Bergamo" raised the 156th Artillery Regiment "Vicenza".

After announcement of the Armistice of Cassibile on 8 September 1943 the Bergamo fought briefly the invading German forces of the German XV Mountain Corps. After the Bergamo surrendered the Germans executed some of the division's officers in retaliation for their resistance.
