Radivojevich was born into a family of Serbian descent in Szentendre near Budapest in the Kingdom of Hungary, which was part of the Habsburg monarchy at the time.

[3] Promoted General-major on 2 April 1807,[4] he found himself commanding a brigade in Hannibal Sommariva's division of Franz Seraph of Orsini-Rosenberg's IV Corps in the War of the Fifth Coalition.

At the Battle of Eckmühl on 22 April 1809 he led his troops which included two battalions of the Walachisch-Illyrian Grenz Infantry Regiment Nr.

[5] He led troops under the overall command of Michael von Kienmayer in an Austrian victory at the Battle of Gefrees on 8 July 1809.

As his columns advanced in mid-August 1813, the Croat and Serb population rose in revolt, facilitating the success of the Austrian army.

[8] While Hiller suffered defeats at Villach in late August[9] and in the Battle of Feistritz on 6 September, Radivojevich's columns scored a series of successes.

[10] Though Nugent sustained a minor setback at Jelšane on 14 September, Rebrovich won an engagement with an Italian force at Višnja Gora on the 16th.

[12] By 5 October, the Franco-Italian army of Eugène de Beauharnais abandoned Illyria and fell back to the Isonzo River.

After hearing that the Kingdom of Bavaria defected to the Coalition on 8 October, Eugène began retreating to the Adige River on the 16th.

[13] Rebrovich's advance guard of the Left Wing Corps crossed the Isonzo on 24 October and scouted in the direction of Palmanova which was garrisoned by 4,000 Franco-Italians.

[14] Covered by effective rearguard actions against Radivojevich's oncoming columns, Eugène's army got safely back to the Adige in the first week of November.

[15] Because Radivojevich was forced to detach troops to mask the fortresses of Venice, Palmanova, and Osoppo, his weakened corps was unable to seriously threaten the Adige line.

[19] Unhappy with Hiller's inability to chase Eugène out of Italy, the Hofkriegsrat replaced him with Count Heinrich von Bellegarde.

[20] When Joachim Murat defected to the Coalition in January 1814, bringing the army of the Kingdom of Naples with him, Eugène abandoned the line of the Adige and fell back to the Mincio River.

[23] Accompanied by Bellegarde, Radivojevich's right-wing got across the Mincio at Borghetto near Valeggio and began to drive back Eugène's weak left wing under Jean-Antoine Verdier.

He and Grenier crossed the river and began rolling up the Austrian left wing after heavy fighting near Pozzolo.

When Eugène and Grenier approached Valeggio from the south, threatening to cut them off from the east bank, Bellegarde and Radivojevich hastily withdrew their soldiers and conceded defeat.

[24] During the Hundred Days when Napoleon returned from exile, Marshal Louis Gabriel Suchet was appointed to defend the border of France from Switzerland to the Mediterranean Sea.

Meanwhile, he and Radivojevich moved north through the Simplon Pass into Switzerland to reach Geneva and turning the French northern flank.

Both Radivojevich and Bubna were pressing back the French when news of Napoleon's abdication arrived to end the fighting.

[29] A court-martial convicted the previous Inhaber Joseph Anton von Simbschen of abuse of office on 12 July 1815.

The Hofkriegsrat then overturned the mild verdict, sentenced Simbschen to a harsher penalty, and stripped him of the title of Inhaber.
