Johann Rudolf von Sporck or Spork[note 1] (27 November 1755 – 10 February 1806) served as an Austrian general during the French Revolutionary Wars.

[2][note 2] In 1792, Sporck became Oberst (colonel) in command of Grand Duke of Tuscany Infantry Regiment Nr.

[7] In the aftermath of the Battle of Courtrai, at Ingelmunster on 12 May he led a brigade consisting of two battalions of the Sztáray Infantry Regiment Nr.

[1] On 29 July 1796, the Austrian army commander Dagobert Sigmund von Wurmser launched the first relief of the Siege of Mantua.

[9] Klenau captured Brescia by surprise on 30 July and his troops were soon joined by the brigades of Sporck and Reuss.

[10] The Battle of Lonato was an intricate series of actions fought on the west side of Lake Garda over the next few days in which Napoleon Bonaparte's French army made its main effort against Quasdanovich's column while holding back the rest of Wurmser's army.

On the night of 3 August, Quasdanovich decided to attack Salò but both Ott and Sporck argued against it on the grounds that their troops were low on ammunition and food.

He appointed Paul Davidovich to lead a corps that would defend the Tyrol while Wurmser marched to Bassano via the Valsugana.

Davidovich's corps numbered 19,555 men of which the brigades of Sporck and Josef Philipp Vukassovich counted 7,840 infantry and 626 cavalry.

[12] Unexpectedly, the French attacked these two brigades with overwhelming force in the Battle of Rovereto in the morning of 4 September, driving them back after a hard combat.

Thinking that they were protected, the 4,800 remaining soldiers of Sporck and Vukassovich bivouacked and began to cook dinner.

However, the French rapidly overran the Preiss Regiment and at 4:00 pm charged into the camp without warning, routing both brigades.

They called for Davidovich's corps to advance south through the mountains while Alvinczi's main army moved east to Verona via Bassano.

Sporck was subordinate to Joseph Louis, Prince of Lorraine-Vaudémont who was tasked to defend Stockach against Claude Lecourbe's French corps.

[2] While the main armies fought to a draw at Engen, Lecourbe's 20,000 Frenchmen evicted Vaudémont's 12,000 Austrians from Stockach.
