# 5th Infantry Division "Cosseria"

The 5th Infantry Division "Cosseria" (Italian: 5ª Divisione di fanteria "Cosseria") was an infantry division of the Royal Italian Army during World War II. The Cosseria was named for the Battle of Cosseria fought in 1796 during the War of the First Coalition. The division recruited primarily in Liguria and its infantry regiments were based in Ventimiglia (89th) and Genoa (90th), while the artillery regiment was based in Albenga.

## History

The division's lineage begins with the Brigade "Salerno" established in Bologna on 1 November 1884 with the 89th and 90th Infantry Regiments.

### World War I

During World War I the brigade fought initially on the Italian front, but in April 1918 it was transferred together with the Brigade "Alpi", Brigade "Brescia", and Brigade "Napoli" to the Western Front in France. There the brigades fought in the Third Battle of the Aisne, Second Battle of the Marne, Battle of Saint-Thierry, and the Hundred Days Offensive.
On 1 November 1926 the brigade was disbanded and its two regiments were transferred to the other brigades: the 89th Infantry Regiment "Salerno" to the V Infantry Brigade and the 90th Infantry Regiment "Salerno" to the I Infantry Brigade. The V Infantry Brigade, which also included the 41st Infantry Regiment "Modena" and the 42nd Infantry Regiment "Modena", was the infantry component of the 5th Territorial Division of Genoa, which also included the 29th Artillery Regiment. On 20 October 1929 the division moved to Imperia and consequently changed its name to 5th Territorial Division of Imperia. On 1 January 1935 the division changed its name to 5th Infantry Division "Cosseria".

### Second Italo-Ethiopian War

In preparation for the Second Italo-Ethiopian War the division was mobilized on 19 August 1935 with the 41st and 42nd infantry regiments and the 29th Artillery Regiment and shipped in September to Benghazi in Libya. In early January 1936 the division was shipped to Eritrea and moved to Adi Quala, where it guarded the supply lines of the Italian divisions fighting in Ethiopia. In March, it started to advance to Addi Onfito, reaching Axum in April 1936 and then continuing to the Adwa area. In September 1936 the division was repatriated.

### World War II

On 25 March 1939 the division ceded all its regiments, except the 89th Infantry Regiment "Salerno", to the newly activated 37th Infantry Division "Modena". On the same date the V Infantry Brigade was dissolved and the 90th Infantry Regiment "Salerno" was transferred from the 1st Infantry Division "Superga" to the Cosseria. The same day the 89th and 90th infantry regiments changed their names to "Cosseria". On 3 September 1939, the depot of the 29th Artillery Regiment "Modena" in Albenga formed the 37th Artillery Regiment "Cosseria" for the division.

#### Invasion of France

On 10 June 1940, it was deployed on the French border, in the area between Cima Longoira and the sea. On 20 June 1940 the Cosseria assaulted French positions at the bridges of Via Aurelia (Corso Francia) and Ponte San Luigi over the Ro San Luigi river near the coast, and on the San Paolo mountain pass near I Colletti, in the Ventimiglia commune. Although the attack through over the bridges was repulsed, the Cosseria succeeded in taking the pass of San Paolo on 22 June 1940. As a result the French forces defending the bridges over the Ro San Luigi and in the Menton area were outflanked, with Italian units capturing rural areas between Castellar and Roquebrune. The Cosseria remained in the occupied France until the middle of August 1940, when it was transferred for coastal defence duties in western Liguria.

#### Eastern Front

The division was one of ten divisions that served on the Eastern Front as part of the Italian Army in Russia. The Cosseria division received orders to move from Liguria to Eastern Ukraine in June 1942. Before leaving Italy the Cosseria exchanged artillery regiments with the 103rd Infantry Division "Piacenza", as the Piacenza's 108th Motorized Artillery Regiment was equipped with modern 75/18 Mod. 34 howitzers, which were considered to be of better use in the Soviet Union than the World War I vintage 75/27 Mod. 06 field guns of the Cosseria's 37th Artillery Regiment. The Cosseria arrived in Horlivka in Southern Ukraine in the beginning of July 1942 and initially was used as reserve of the Italian XXXV Army Corps. Following the attacking forces the Cosseria arrived in Stalino (today Donetsk) on 15 July 1942 and in Luhansk on 25 July 1942. It crossed the Seversky Donets river at Stanytsia Luhanska. In the first half of August the Cosseria was transferred to the front-line on the Don river, to the north of the 3rd Infantry Division "Ravenna", taking positions between Novaya Kalitva and Verhny Mamon. From 20 August until 26 August 1942, the Cosseria repelled a Soviet assault without giving up any ground. Further Soviet attacks at Krasno-Orehovo and Derezovka on 11 September 1942, succeeded in pushing back the Cosseria troops, but all losses were recovered by Italian counter-attacks on 12 September 1942. Soon after, the division was moved back to the reserve.

#### Operation Little Saturn

On 12 December 1942 Soviet forces began Operation Little Saturn and the Cosseria was hit by powerful Soviet attacks. By 24 December 1942 the division was badly decimated and relieved from frontline duty by German units. The Cosseria's remaining men were partly used to reinforce the 3rd Infantry Division "Ravenna", and partly used to protect supply lines around Rovenky. The rapidly deteriorating situation forced the Cosseria's remnants to retreat to the south-west, first maintaining a front-line, and then in several separate columns. The street fighting began in Rovenky on 2 January 1943. During the Soviet Voronezh Front's operations in the Upper Don area under Golikov, Soviet cavalry struck out very successfully for Valuiki and under the pale winter sun on 19 January the horsemen in black capes and flying hoods charged down the hapless Italians, killing and wounding more than a thousand before the brief resistance by the fleeing, hungry and frostbitten men of the 5th Infantry Division ended.
The few remaining soldiers of the Cosseria then reached Izium, where they linked up with other Axis forces. The further retreat route was through Kharkiv, Okhtyrka, Romny, Pryluky, Nizhyn, finally reaching Novobelitsa at the Southern outskirts of Gomel on 7 March 1943. The division was repatriated in May 1943 and moved to Tuscany, where it started to re-form. On 25 July 1943 the division was assigned for police duties at Sesto San Giovanni. After the announcement of the Armistice of Cassibile on 8 September 1943 the division was dissolved by invading German forces on 12 September 1943.
