Part of the regiment's personnel was then assigned to the 2nd Line Brigade, which fought on the French side in the War of the Second Coalition against the Austrians.

In May 1814 King Victor Emmanuel I returned from exile in Sardinia and in July of the same year the Regiment of "Alessandria" was reformed.

In 1975, the regiment was disbanded and its flag and traditions assigned to the 17th Infantry Battalion "San Martino", which trained recruits destined for the Motorized Brigade "Acqui".

In 1713, the war ended with the Peace of Utrecht, which transferred the Kingdom of Sicily and parts of the Duchy of Milan to Savoy.

The war ended with the 1720 Treaty of The Hague, which restored the position prior to 1717, but with Savoy and Austria exchanging Sardinia and Sicily.

In January 1794, the Regiment of "Chablais", which by then consisted only of soldiers recruited in the territories of King Victor Amadeus III, was taken into national service.

In March 1796, Napoleon Bonaparte arrived in Italy and took command of the French forces, with which he defeated the Royal Sardinian Army in the Montenotte campaign within a month.

On 28 April 1796, King Victor Amadeus III had to sign the Armistice of Cherasco and on 15 May 1796 the Treaty of Paris, which forced Sardinia out of the First Coalition.

Part of the personnel of the Regiment of "Alessandria" choose to remain in service and were assigned to the 2nd Line Brigade, which fought on the French side in the War of the Second Coalition against the Austrians.

[5][6][7][8] After returning from exile King Victor Emmanuel I abolished all the freedoms granted by the Napoleonic Code and established a fiercely oppressive rule.

[5][6][7][8] On 31 May 1821, the four infantry brigades, which had sided with the revolutionaries, were stricken from the rolls of the Royal Sardinian Army and their personnel dismissed from service, while the troops of the regiments, who had not participated in the revolt, were assigned to four provisional line battalions.

On 23 March 1849, after being defeated in the Battle of Novara, King Charles Albert abdicated in favour of his son Victor Emmanuel.

On 24 March, the new king met with the Austrian Field Marshal Radetzky at Vignale and agreed to an armistice, which ended the First Italian War of Independence.

On 5 May 1860, Giuseppe Garibaldi's Expedition of the Thousand set off, with the support of the Sardinian government, from Genoa and landed on 11 May in Marsala in Sicily.

For the rest of the year the Brigade "Acqui" participated in the Italian attempts to dislodge the Austro-Hungarian forces from the slopes and hills of the Karst plateau.

Between 18 July and 3 August 1915, during the Second Battle of the Isonzo, the brigade renewed the attack against Monte Sei Busi and the 18th Infantry Regiment managed to advance to the edge of the Austro-Hungarian positions above Vermegliano.

During the next months the brigade pushed its trenches forward to establish better attacking positions for the Third Battle of the Isonzo, which began on 18 October 1915.

The next day an Austro-Hungarian counterattack forced the two battalions, which had suffered 600 casualties, to abandon the trench and fall back to the original Italian lines.

On 12 August 1916, the 18th Infantry Regiment was awarded a Silver Medal of Military Valor for its conduct in the Karst battles in the first two years of the war.

However already after 3 days, the Brigade "Acqui", which had lost 2,000 men in the unsuccessful attack, had to be pulled out of the front and sent to the rear to be rebuilt.

On 19 August 1917, during the following Eleventh Battle of the Isonzo, the brigade attacked Austro-Hungarian positions near Kostanjevica na Krasu, but failed to achieve its objectives while losing almost 1,600 men.

[5][10] On 13 December 1917, the brigade was assigned to the French 65th Infantry Division, which manned the Piave front in the Vidor sector.

On 1 November 1918, during the decisive Battle of Vittorio Veneto the brigade was sent to Ala as reserve of the XXIX Army Corps, which was pursuing the retreating Austro-Hungarians through the Lagarina Valley.

On 3 November 1918, the brigade passed through Rovereto, while the vanguards of the XXIX Army Corps entered Trento the same day.

In 1935-36, the 17th Infantry Regiment "Acqui" provided eight officers and 179 troops to units deployed to East Africa for the Second Italo-Ethiopian War.

On 10 June 1940, Italy invaded France and the "Acqui" division attacked French forces in the Maddalena Pass-Argentera-Colle del Ferro area.

[5][16][17] On 6 December 1940, the "Acqui" division was ordered to move to Albania to reinforce the crumbling Italian front in the Greco-Italian War.

In early February 1941, the division was pulled back to Smokthinë in the Shushice valley to rest and refill its depleted ranks.

After several days of fighting, at 11:00 hours on 22 September, Gandin ordered his division, which had lost 1,315 men and run out of ammunition, to surrender.

The same year, the regiment was transferred from the Mechanized Brigade "Acqui" to the army's Non-Commissioned Officers School in Viterbo.
