 Having heard of Mihailović's reaction, without consulting with Drljević, Đurišić ordered the movement of the army to the west.Under the agreement, Đurišić's army was obliged to cross the Sava River into Slavonia, and from Slavonski Brod continue the march in the direction of Zagreb as the Montenegrin National Army.Instead, Đurišić kept moving on a route south of the river, towards the Motajica mountain and the Lijevče field, a large plain between the Bosna, Vrbas and Sava Rivers.
