The small garrison of Koszeg consisting of 700 men led by Croatian Captain Nikola Jurišić blocked the way to Vienna for the main Ottoman army.

In the meantime, 8,000-16,000 Ottoman light cavalry,[1] under Kazim Bey, raided Styria and bypassed Wiener Neustadt, and southern parts of Lower Austria.

When Kazim Bey was informed of the retreat of the Ottoman main army under the command of Suleyman the Magnificent, he gathered his raiders in Pottenstein to link up with the main army.

An Austrian detachment under Sebastian Schertlin von Burtenbach managed to drive the Ottomans into the only remaining open valley, where a large army of 20,000 Landsknechts, 1,000 heavy cavalry, 1,000 light cavalry from Hungary, and artillery led by Palatinian Count Frederick, Count Bálint Török, and Johann Katzianer were waiting for them.

Kazim Bey's Ottoman army was completely destroyed,[1]
