On 12 July 1859, the war ended with the Armistice of Villafranca, which called for the rulers of the occupied territories to be restored to their thrones.

However, neither the Kingdom of Sardinia nor the Sardinian installed governments in the occupied territories wished for a return of the rulers.

On 30 November 1859, the Duchy of Parma and Piacenza, the Duchy of Modena and Reggio, and the Papal Legations of the Romagne were united under the Royal Government of Emilia, which, on 1 January 1860, was redesignated as the Royal Provinces of Emilia.

In the evening of 8 September 1943, the Armistice of Cassibile, which ended hostilities between the Kingdom of Italy and the Anglo-American Allies, was announced by General Dwight D. Eisenhower on Radio Algiers and by Marshal Pietro Badoglio on Italian radio.

Germany reacted by invading Italy and the 1st Engineer Regiment was disbanded soon thereafter by German forces.

[2] On 28 October 1932, the Royal Italian Army disbanded the 2nd Radio-Telegraphers Regiment in Novi Ligure.

During World War II, the depot of the 1st Miners Regiment in Novi Ligure mobilized the I, II, III, IV, IX, XI, and CIII miners battalions, and the XV and XVI engineer battalions.

The 1st Miners Regiment was disbanded by invading German forces after the announcement of the Armistice of Cassibile on 8 September 1943.

The grouping consisted of the IV, VII, and XX engineer battalions, the 1st and 2nd cableway companies, and a depot.

At the end of 1955, the regiment consisted of the following units:[2] On 1 January 1964, the XX Engineer Battalion was renamed XIV Army Corps Engineer Battalion, and on 16 January of the same year, the 2nd Cableway Company was merged into the 1st Cableway Company.

The battalion was named for the great pre-alpine Lake Garda, which lies between Lombardy, Veneto and Trentin.
