The 5th Division "Cosseria" participated in the Second Italo-Abyssinian War, with parts of it forming 105th Division Cosseria II. In August–September Cosseria was moving to Benghazi, where it stayed until December, 1935. Casseria was transferred to Adi Quala in Eritreain the beginning of January, 1936. It was mostly tasked with population control and supply lines protection behind the front-line. In March, it started to advance to Addi Onfito, reaching Axum in April, 1936 and spreading in Adwa area. It has returned to Italy in September, 1936, and was reorganized as a binary division 25 March 1939. 10 June 1940, it was deployed on the French border, in the strip from Cima Longoira to the sea. 20 June 1940, the Cosseria division has started assault on French positions at bridges of Via Aurelia and Ponte San Luigi over Ro San Luigi river near coast, and mountain pass San Paolo near I Colletti, in Ventimiglia commune. Although the thrust through the bridges over Ro San Luigi river was initially repulsed, Cosseria has succeeded in taking over pass San Paolo 22 June 1940. As result, the French forces defending bridges over Ro San Luigi and Menton area were outflanked, with Italians capturing rural areas between Castellar and Roquebrune. Cosseria has remained in the occupied territory until middle of August, 1940, than it was transferred to coastal defence duties in Western Liguria.
Deployment in Russia
The division was one of the twelve divisions that served on the Eastern Front as part of the Italian Army in Russia. The Cosseria division has received orders to move from Liguria to Russia in June, 1942, accordingly arriving to Horlivka in the beginning of July, 1942. It was used initially as the reserve of 35th Army Corps. Following attacking forces, Cosseria has arrived to Donetsk 15 July 1942, and in Luhansk 25 July 1942. It crossed Seversky Donets River at Stanytsia Luhanska. In the first half of August, the Cosseria fas transferred to the front-line at the Don river, on the north of 3rd Mountain Infantry Division Ravenna, taking positions between Novaya Kalitva and :ru:Верхний Мамон|Verhny Mamon. From 20 August until 26 August 1942, the Cosseria has repelled a Soviet assault without giving up any ground. Further Soviet attack at Krasno-Orehovo and Derezovka 11 September 1942, succeeded in pushing back the Cosseria troops, but all losses were recovered by Italian counter-attack 12 September 1942. Soon after, the division was moved back to the reserve. The Cosseria division was in complete rout by 24 December 1942. The division was relieved of front-line duty by German units. The remains were partly used to reinforce the Ravenna division, and partly used to protect supply lines around Rovenky. But rapidly deteriorating situation has forced the Cosseria remnants to retreat to the south-west, first maintaining front-line, and then in several columns. The street fighting has begun in Rovenky 2 January 1943. During the Voronezh Front 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 Italian Infantry Division ended. The soldiers of Cosseria then reached Izium, where they linked with other Axis forces. The further retreat route was through Kharkiv, Okhtyrka, Romny, Pryluky, Nizhyn, finally reaching Novobelitsa at the southern outskirts of Gomel at 7 March 1943. The division was removed from duty and moved to the Tuscany province of Italy during late April - early May, 1943, where it started to re-form. The brief tour to Milan was done at 25 July 1943, and after Cosseria was assigned for the police duties at Sesto San Giovanni. The division has ceased to exist 12 September 1943, with troops mostly surrendered to German in the aftermath of the Armistice of Cassibile.
