As a newly promoted general officer in Italy, he led a brigade in an all-night action against the French at Codogno, part of the Battle of Fombio in May 1796.

On 21 December 1748, Schübirz was born at Olomouc (Olmütz), a fortress town in the province of Moravia in Habsburg monarchy (today in the Czech Republic).

[2] On 4 March 1796, Schübirz found himself elevated to the rank of Generalmajor in Johann Peter Beaulieu's Austrian army of Italy.

The small Austrian Auxiliary Corps, which fought under Sardinian command, was placed in a tight spot when its allies laid down their arms.

[5] Since its previous commander, Giovanni Marchese di Provera had been captured at the Battle of Millesimo,[6] Beaulieu appointed Schübirz to bring the Corps to safety.

[7] As Beaulieu fell back into the Duchy of Milan, Schübirz's troops reached a position at Lomello on the Agogna River on 2 May.

[9] By dawn on the following day, Bonaparte managed to slip Claude Dallemagne's 5,000-strong advance guard across the Po River behind Beaulieu's strategic left flank.

During the day, the rapidly moving French defeated Anton Lipthay de Kisfalud at the Battle of Fombio and pressed forward to occupy the town of Codogno.

Hoping to cut his way through in the morning, the Austrian commander sent Schübirz toward Codogno with two battalions of the Reisky Infantry Regiment Nr.

As the troops reached the town square, they were ambushed by soldiers of the Reisky Regiment and soon both sides were firing blindly into the darkness.

After the French rounded up a number of Austrian prisoners, they found Laharpe shot dead, possibly by friendly fire.

[12] Given some breathing room by his lieutenant's all-night combat, on 9 May Beaulieu directed his troops to cross the Adda farther north at Lodi.

Once he arrived on the field, he launched an effective attack that saved the village of Solferino from capture and helped halt the French advance.

Schübirz led the rear guard of three squadrons of hussars, which were the last Austrians to cross the Mincio at the Borghetto bridge.

[23] He was present in the Second Battle of Bassano on 6 November, where his troops were called upon to reinforce Lipthay's roughly handled brigade near Fontaniva.

[25] At the Battle of Caldiero on 12 November, Prince Friedrich Franz Xaver of Hohenzollern-Hechingen held off Bonaparte's initial attacks.

But another collapse of Austrian resistance at Belfiore allowed Bonaparte to concentrate against Arcole and the village finally fell at 5:00 PM on the 17th.
