53rd Infantry Division "Arezzo"

The division's lineage begins with the Brigade "Arezzo" established during World War I in Castelfranco Veneto on 18 May 1916. The brigade consisted of the 225th Infantry Regiment and 226th Infantry Regiment, which were manned by reservists. The brigade fought on the Italian front and for their conduct the brigade's two infantry regiments were awarded Italy's highest military honor, the Gold Medal of Military Valour.[5][6] After the war the regiments raised during the war were dissolved, with the exception of those, who had been awarded a Gold Medal of Military Valour.

On 30 September 1926 the brigade command and 226th Infantry Regiment "Arezzo" were disbanded, while the 225th Infantry Regiment "Arezzo" was assigned to the XXIV Infantry Brigade. On 1 March 1938 the 18th Infantry Division "Matauro" reactivated the 226th Infantry Regiment "Arezzo" in Macerata. On 24 May 1939 the 53rd Infantry Division "Arezzo" was activated in Macerata and was assigned its two namesake infantry regiments and the newly raised 53rd Artillery Regiment "Arezzo".[2][7][8]

The Arezzo was transferred to Albania in June 1939 and based in Shkodër in the country's North. After the Arezzo had left for Albania the 49th Infantry Division "Parma" was activated on 12 September 1939 and housed in some of the barracks of the Arezzo in mainland Italy. From 30 October 1940 units of the division were sent to the South of Albania to reinforce Italian units fighting the Greco-Italian War. From 20 November the entire division was engaged in combat against Greek forces in the Shkumbin valley. After Greek forces advanced on the Arezzo's right flank the division was forced to retreat on 2 December.[2] The Arezzo suffered serious losses in the fighting between 29 November and 3 December 1940.[9]

From 2 January 1941 Greek forces increased the pressure on the Arezzo, which lost some of its positions. On 10 January the Greeks managed to take more positions of the Arezzo and fighting continued into February. On 20 February 1941 the heavily decimated Arezzo was sent to the rear to be brought back up to strength. In preparation for the Invasion of Yugoslavia the Arezzo moved to the Lake Ohrid area on border with Yugoslavia on 28 March 1941. On 9 April 1941 the Arezzo crossed the border and with the aim of capturing Ohrid and Struga. After fierce fighting the Arezzo captured both cities on 11 April. The division then advanced towards Trebeništa and Vranište.[2]

On 17 April the Arezzo was sent to the Greek front for the Italian spring offensive. At the war's end the division reached Sarantaporos, where it was engaged in mopping up operations. After the war the Arezzo moved to Korçë in Albania where it performed anti-partisan duties until September 1943. After the announcement of the Armistice of Cassibile on 8 September 1943 the division was disarmed by partisans.[2]
