Editing Jurij Vega (section)

==Military service==
Vega left Ljubljana five years after graduating and entered military service in 1780, becoming a professor of mathematics at the Artillery School in Vienna. Around this time, he began using the surname ''Vega'' instead of his original surname, ''Veha''.

At the age of 33, Vega married Josefa Svoboda (also spelled Jožefa Swoboda) (1771–1800), a Czech noblewoman from [[České Budějovice]], who was 16 years old at the time.

Vega participated in several military campaigns. In 1788, he served under Austrian Imperial Field Marshal [[Ernst Gideon von Laudon]] (1717–1790) in a campaign against the [[Ottoman Empire]] at [[Belgrade]]. His command of several [[mortar (weapon)|mortar]] batteries significantly contributed to the fall of the Belgrade fortress.

Between 1793 and 1797, he fought against [[French Revolutionary]] forces under the command of Austrian General [[Dagobert Wurmser|Dagobert-Sigismond de Wurmser]] (1724–1797) as part of the European coalition allied with Austria. Vega participated in battles at [[Fort-Louis|Fort Louis]], [[Mannheim]], [[Mainz]], [[Wiesbaden]], [[Kehl]], and [[Diez, Germany|Diez]].

In 1795, he designed two 30-pound (14 kg) mortars with conically drilled bases and larger charges, increasing their firing range to up to 3,000 metres (3,300 yards). By comparison, the older 60-pound (27 kg) mortars had a range of only 1,800 metres (2,000 yards).

In September 1802, Vega was reported missing. After a few days, his body was found. A police report concluded that his death was accidental. It is believed that he died on 26 September 1802 in [[Nußdorf, Vienna|Nußdorf]], a district along the [[Danube]], near [[Vienna]], the capital of [[Austria]].
