World War I On 22 May 1916, the
depot of the
2nd Engineer Regiment (Sappers) in
Casale Monferrato formed the LI Sappers Battalion. The battalion consisted of a command, and the 104th, 134th, and 156th sappers companies. The battalion served on the
Asiago Plateau until it was disbanded on 1 March 1918. With the flag the battalion also received the traditions of all preceding engineer units numbered 51, as well as the traditions of the Engineer Battalion "Legnano" and the 12th Engineer Regiment, which had been based in Palermo from 1 October 1922 to July 1943, and whose motto the "Simeto" battalion inherited. The 51st Engineer Battalion "Simeto" consisted of a command, a command and services company, the 1st Engineer Company, and the Engineer Park Company. On 11 December 1985, the battalion formed the 2nd Engineer Company.
Recent times After the
Cold War the Italian Army began a reorganization of its forces: on 19 September 1992, the 51st Engineer Battalion "Simeto" in Palermo lost its autonomy and the next day the battalion entered the reformed
4th Pioneer Regiment as Pioneer Battalion "Simeto". As the flag of the 4th Engineer Regiment was still assigned to the
4th Engineer Battalion "Orta" in
Trento, the reformed regiment continued to use temporarily the flag of the "Simeto" battalion. On 3 October 1993, 4th Engineer Battalion "Orta" lost its autonomy and the next day the battalion entered the reformed
1st Pioneer Regiment as Pioneer Battalion "Orta". As the flag of the 1st Engineer Regiment was still stored at the
Shrine of the Flags in the
Vittoriano in
Rome, the 1st Pioneer Regiment continued to use temporarily the flag of the 4th Engineer Regiment. On 13 October 1995, the
2nd Engineer Battalion "Iseo" in
Bolzano was disbanded. On the same day, the flag of the 2nd Engineer Regiment, which had been assigned in 1975 to the
2nd Miners Battalion "Iseo", was transferred from Bolzano to Trento, where, upon the arrival of the flag, the 1st Pioneer Regiment was renamed 2nd Engineer Regiment, while the regiment's Pioneer Battalion "Orta" was renamed Sappers Battalion "Iseo". Afterwards, the flag of the 4th Engineer Regiment was transferred from Trento to Palermo, where it arrived and was assigned to the 4th Pioneer Regiment on 24 October 1995. Subsequently, the flag of the 51st Engineer Battalion "Simeto" was transferred to the Shrine of the Flags in the
Vittoriano in Rome for safekeeping. == External links ==
