The Cannone da 70 A Mont.,[3] in 1926 officially renamed Cannone da 70/15[4] was a mountain gun used by Italy during World War I. By World War II it had been relegated to the infantry gun role in units assigned to Italian East Africa.[2]

Background

The 70/15 was designed in 1902 by Italian artillery Captain Regazzi to replace the Canonne da 7 BR Ret. Mont. that was first introduced in 1881. The 70/15 was technically obsolescent when it went into service in 1904 but it took the Italians almost a decade to field its replacement the Cannone da 65/17 modello 08/13.

Design

The 70/15 was a breech-loaded mountain gun with an interrupted screw breech, a box trail carriage, two wooden-spoked steel-rimmed wheels. There was no recoil mechanism, no gun shield, no traversing mechanism, and elevation was controlled by a jackscrew beneath the breech. It could be broken down into four mule loads for transport or hooked to a limber for towing.

History

The 70/15 was first used during the Italo-Turkish War by the 3rd Mountain Artillery Regiment. The 70/15 was still in service during World War One due to insufficient numbers of more modern replacements. Due to its light, simple, inexpensive, and rugged construction Ansaldo built 710 70/15s barrels from 1916 to 1918,[5] while Armstrong Pozzuoli and other state arsenals built the gun carriages.[6] It remained in colonial service throughout World War II. It was gradually phased out of the mountain role and given a new role as an infantry support gun.[7]

After World War One most were transferred to the Italian Border Guard. At the outbreak of World War Two, 92 guns were still in service with the I Group/1° GaF Artillery, the VII Group/2° GaF Artillery, and IIbis Group/3° GaF Artillery in Albania.[8] In Italian East Africa, the 70/15 was used by the XCI Colonial Artillery Group/XCI Colonial Brigade, the XCII Colonial Artillery Group/XCII Colonial Brigade, and the CI Colonial Artillery Group.[9]
