The army conducted a successful crossing of Sava and performed an offensive into Syrmia (then part of Austria-Hungary) but was recalled when Second invasion of Serbia (also known as the Battle of Drina) began.

He restored morale and discipline (which had started to waver) in the army, by insisting on a deeper withdrawal before the Austro-Hungarians, all the way to Gornji Milanovac.

Perhaps as a consequence of this Mišić was in favor of halting and making a final stand against the Central Powers forces when the High Command ordered retreat across Montenegro and Albania to Italian-held Durrës and Vlorë (at the time Serbian Army was defending itself in Kosovo from three sides and was in danger of becoming surrounded).

From the Italian-held ports the Serbian Army was transported by Allied ships to Corfu, and a smaller part to French-held Bizerte to recuperate and reorganise.

This army liberated Belgrade, and subsequently crossed into Vojvodina and advanced as far as present-day border between Serbia and Hungary by the time of the Armistice.
