The Battle of Krško of 5 February 1573 has a similar rhythm to the Enthronement. The noble army moves from the left towards the central group and cuts the peasant line. In the centre of the painting, a soldier of the noble army has mortally wounded a peasant in blue with a spear. On the right, the peasants can be seen retreating in panic.

The Battle depicts the first clash between the peasants and the noble army during the Croatian–Slovenian Peasant Revolt led by Matija Gubec. Near Krško, the rebellious peasants were intercepted by the Uskok captain Jobst Joseph von Thurn and defeated. Those who were not killed or drowned in the Sava fled back to Krško, which was then sacked by Thurn’s troops. Not even the women and children were spared.

The battle scene is one of seven images painted by Gojmir Anton Kos in the competition to design decorations for the grand corridor of the governor’s palace in Ljubljana (today’s Presidential Palace). The competition aimed to encourage the artistic historicisation of Slovenia’s past and was to some extent inspired by achievements in Croatian, Polish and Czech painting. Although the principal models for the compositions came from the (German) centres of academicism, artists such as the Polish painter Jan Matejko (1838–1893), the Czech painter Alfons Maria Mucha (1860–1939), the Serbian painter Paja Jovanović (1859–1957) and the Croatian painters Oton Iveković (1860–1939), Vlaho Bukovac (1855–1922) and others represented, with their monumental paintings and cycles, pan-Slavist examples of how to unite, through technical skill and ambition, the spheres of art, history, national identity and politics.
