The battalion belongs to the Italian Army's Alpini infantry speciality and was assigned to the Alpine Brigade "Orobica".

The battalion was reformed again in January 1941 and sent to Albania to reinforce the 6th Alpini Regiment, which was suffering heavy casualties in the Greco-Italian War.

In summer 1942, the "Val Chiese" battalion deployed with the 6th Alpini Regiment to the Eastern Front, where the regiment and "Val Chiese" battalion were almost completely destroyed during the Red Army's Operation Little Saturn in winter 1942–43.

The battalion's anniversary falls on 26 January 1943, the day of the Battle of Nikolayevka, during which the 5th Alpini Regiment and 6th Alpini Regiment broke through Soviet lines and opened an escape route for the retreating troops of the Alpine Army Corps.

The two battalions were assigned to the 5th Alpini Group, with which they participated in June 1940 in the Italian invasion of France.

[2][3][8] In November 1940, the 2nd Alpine Division "Tridentina" was transferred to Albania to shore up the crumbling Italian front during the Greco-Italian War.

By now the "Tridentina" division had retreated into Albania, where it continued to fight until the German invasion of Greece in April 1941.

The corps was assigned to the Italian 8th Army, which was readied to be deployed in summer 1942 to the Eastern Front.

[2][3][8][12][13][14] In July 1942 the three alpine division arrived in Eastern Ukraine, from where they marched eastwards towards the Don river.

[2][3][8][13][14][15] On the evening of 17 January 1943, the Alpine Army Corps commander, General Gabriele Nasci, ordered a full retreat.

The 40,000-strong mass of stragglers — Alpini and Italians from other commands, plus German and Hungarians — followed the "Tridentina", which led the way westwards to the new Axis lines.

On the morning of 26 January 1943, the spearheads of the "Tridentina' reached the hamlet of Nikolayevka, occupied by the Soviet 48th Guards Rifle Division.

General Nasci ordered a frontal assault and at 9:30 am the Battle of Nikolayevka began with the 6th Alpini Regiment leading the first attack.

By noon the Italian forces had reached the outskirts of the village and the Alpine Army Corps' Chief of Staff General Giulio Martinat led the 5th Alpini Regiment forward for another assault, durich which General Martinat fell.

[15] By sunset the Alpini battalions were still struggling to break the Soviet lines and in a last effort to decide the battle before nightfall General Luigi Reverberi, the commanding General of the "Tridentina" division, ordered a human wave attack on the Soviet lines.

[2][3][8][13][14][15] On 11 February 1943, the survivors were counted and 1,646 men of the 6th Alpini Regiment had were listed as killed or missing.
