It was formed during World War I, as part of the 11th German-Bulgarian Army, combining members of both nationalities and saw service on the Macedonian front.

The barrage continued until 6:30 a.m. on 9 May, when a combined Italian, French and Russian infantry assault was launched along a 23 kilometres (14 mi) long line.

To the right the 61st Italian Regiment took advantage of the dust cloud, left by the barrage, and managed to capture a forward trench that the Bulgarians had previously evacuated in face of the Allied artillery fire.

The 45th German Infantry Regiment managed to regain the ground it lost after the Italian left flank came under heavy fire from Piton Rocheaux.

At 9:45 a.m., a second wave of Italian infantry rushed into no man's land, once again failing to secure its objectives and suffering heavy losses.

[4][5][2] On 15 September 1918, a combined force of Serbian, French and Greek troops attacked the Bulgarian-held trenches in Dobro Pole ("Good Field").

The assault and the preceding artillery preparation had devastating effects on Bulgarian morale, eventually leading to mass desertions.

Effectively employing machine gun and artillery fire the Bulgarians managed to stall the Allied advance on the Doiran sector.

The Italians were ordered to strike Kičevo with the aim of preventing the enemy forces stationed at Monastir from reaching the railroad hub in Uskub, the 11th Colonial French Division was instead tasked with securing Prilep.

Half an hour later the French entered Prilep, to the east Franco–Serbian columns marched on Štip, Veles, Brod and through the Peristeri mountain range.
