Joseph Ocskay von Ocskó (1740 – 8 December 1805) joined the army of the Habsburg monarchy and rose to the rank of general officer during the French Revolutionary Wars.

However, he received the Knight's Cross of the Military Order of Maria Theresa on 21 December 1789, and was granted the noble title Freiherr on 28 July 1790.

[1] In late July 1796, Ocskay led a brigade in the Right Column under Peter Quasdanovich in the first attempt to relieve the Siege of Mantua.

[3] On 29 July, the brigades of Ocskay and Peter Ott surprised and defeated Pierre Sauret's French troops at Gavardo and Salò on the west side of Lake Garda.

Since 400 Frenchmen led by Jean Guieu barricaded themselves in a palace in Salò, Ocskay's troops besieged the enemy soldiers while Ott pursued operations farther to the south.

After being released in a prisoner exchange, Ocskay led a brigade in Paul Davidovich's Tyrol Corps during the third attempt to relieve Mantua.

[11] These victories proved hollow when the French defeated the main Habsburg army at the Battle of Arcole on 15–17 November.

Shortly before the battle, Ocskay's soldiers were ordered to join the troops massing on the slopes of Monte Baldo to the west.

Later-arriving Austrian units led by Adam Bajalics von Bajahaza were cut off by Masséna and Guieu and forced to surrender.

[1] His son, Franz Ocskay von Ocskó (1775–1851) became a noted entomologist who wrote several articles describing new species of insects.
