[2][6] On 28 October 1940 the Bari embarked for Vlorë in Albania to reinforce the Italian units engaged in the Battle of Pindus of the Greco-Italian War.

Greek forces tried to capture the key road junction of Perati Bridge to the rear of the 139th Infantry Regiment.

The defence of Perati Bridge then degenerated into bloody rout, with few Italian survivors fleeing to Leskovik and Cerckë, where they joined the 140th Infantry Regiment.

After severe fighting the remnants of the Bari were relieved from front line duties in the Këlcyrë area on 29 November 1940.

On 23 December 1940 the Bari's reserve units were sent forward to stop the Greek breakthrough south of Qarrisht' e Fratarit.

The Greek ski-equipped light forces continued to try to envelop the Bari positions from the north in order to open the way to Berat, which resulted in a particularly violent clash on 15 January 1941, but the Italian front line was stabilized nonetheless.

After repulsing another Greek assault around Vinokash and Kajcë 29 January 1941, the Bari was replaced by 51st Infantry Division "Siena" and sent to the rear at Roskovec for reorganization.

After the end of the war in Greece the Bari was one of the divisions earmarked for the proposed invasion of Malta, which was ultimately cancelled.

In June 1941, the division was repatriated to Apulia, where it performed coastal defence duties from Brindisi to Taranto.

In April 1943 the division shipped to Oristano in the North of Sardinia, where it was tasked with coastal defense duties, as part of the XXX Corps.
