The 51st Infantry Division "Siena" (Italian: 51ª Divisione di fanteria "Siena") was an infantry division of the Royal Italian Army during World War II. The Siena was formed on 15 September 1939 and named for the city of Siena. The division was a Campanian unit and its men were almost entirely from Naples. After fighting in the Greco-Italian War the division was sent to Crete as garrison unit. There the division was disbanded by invading German forces after the Armistice of Cassibile was announced on 8 September 1943.
History
The division's lineage begins with the Brigade "Siena" established by order of the Provisional Government of the Grand Duchy of Tuscany of 2 July 1859 with the 3rd and 4th infantry regiments. On 25 March 1860 the Brigade "Siena" entered the Royal Sardinian Army three days after the Kingdom of Sardinia had annexed the United Provinces of Central Italy, which included the Grand Duchy of Tuscany. Already before entering the Royal Sardinian Army the brigade's two infantry regiments had been renumbered on 30 December 1859 as 31st Infantry Regiment and 32nd Infantry Regiment.
World War I
The brigade fought on the Italian front in World War I. On 9 December 1926 the brigade command and 32nd Infantry Regiment "Siena" were disbanded, while the 31st Infantry Regiment "Siena" was transferred to the XXV Infantry Brigade.
On 15 September 1939 the 51st Infantry Division "Siena" was activated in Naples. On the same date the 31st Infantry Regiment "Siena" and the newly raised 51st Artillery Regiment "Siena" joined the division. On 24 September 1939 the 32nd Infantry Regiment "Siena" was reactivated in Caserta joined the division.
World War II
On 10 June 1940 the Siena was transferred to Piedmont as reserve unit during the Italian invasion of France. In October 1940 the Siena arrived in Albania for the Greco-Italian War, which began on 28 October 1940. Initially the Siena was deployed in the Delvinë-Konispol region as part of VIII Army Corps, covering the border from the coast to Mal Stugarë, where the 23rd Infantry Division "Ferrara" was deployed. The division participated in the Italian offensive towards the Greek city of Ioannina, but failed to cross the Thyamis river until 6 November 1940 due to heavy Greek resistance. On 6 November 1940 a beachhead across the Thyamis was established, but the division immediately had to turn to a defensive stance because of the rapid pace of Greek reinforcements arriving. On 14 December 1940, the Siena repelled Greek probing attacks, but by 19 December the division retreated with the other Italian forces from the line between Himarë to Kallarat. The Siena was able to stop the Greek advance just short of the valley of Shushicë, on the mountaintops of Mali i Çorajt to Horë-Vranisht. The fighting was bloody, with the infantry regiments of the Siena down to battalion strength. On 24 December 1940 the 33rd Infantry Division "Acqui" arrived to stabilize the front and on 26 December 1940 the Siena was relieved from front line duties and sent to Berat to regroup.
To plug the gap caused by the Greek breakthrough after the Capture of Klisura Pass the Siena returned to the front on 25 January 1941 along the line from Qafa e Kiçokut to Monastery Hill (Height 731) north of Këlcyrë. The division managed to stop the breakthrough, despite incessant Greek attacks. On 8 February 1941 the division once more was sent to the rear. After being rebuild the Siena participated in the Italian Spring Offensive, which started on 19 March 1941 and ended with disastrous results for the Italian troops. In April during the Battle of Greece the Siena captured Këlcyrë on 14 April 1941. On 16 April 1941 the Siena was ordered to stop, while the 47th Infantry Division "Bari" took over frontline duties.
After the fighting ended the Siena was reorganized in the Osum valley. At the beginning of May 1941 the Siena was sent to the Peloponnese in Greece, where it formed garrisons in Corinth, Nemea, Argos and Nafplion. In late September 1941 the division was transferred to the eastern part of the island of Crete, where it assumed the title of Italian Troops in Crete Command (Italian: Comando Truppe Italiane in Creta). On 1 March 1942 the division was reinforced by the LI Special Brigade. On 18 April 1943 parts of the Siena defeated an Allied landing attempt on the island of Koufonisia. The division, together with the LI Special Brigade remained in Crete until September 1943, when Italy signed the Armistice of Cassibile with the Allies. The German forces of the Fortress Crete disarmed the Siena and LI Special Brigade on 9 September 1943.
In October 1943 about 2,000 Italian POWs from Crete were killed, when the ship MS Sinfra that transported them to mainland Greece was sunk by US and British planes. Another 2,670 Italian POWs from Crete drowned in February 1944, when the ship SS Petrella was torpedoed by the British submarine HMS Sportsman.
