In November 1916 the Entente had managed to capture Monastir but it was impossible for them to use the city because it was within the range of the Bulgarian artillery in the Pelister mountain range to the West and Hill 1248 to the north of the city.
The Allied commander-in-chief, Maurice Sarrail, made plans for a large spring offensive in 1917, besides attacking the Crna Bend and Doiran, he also planned an attack north and west of Monastir to give the city, which was always under fire, a wider breathing space.

For this attack, Sarrail disposed of six infantry divisions: the French 57th, 11th Colonial, 16th Colonial, 76th and 156th Infantry Divisions.
