The king appointed Zrinski as the commander-in-chief of the Croato-Hungarian troops, who, with his successful enterprise, set fire to the Osijek bridge that provided supplies to the Turkish garrisons across the Danube, but due to the court's delay, he was unable to capitalize on the victory.

Due to the reckless campaign in Poland launched by George II Rákóczi, huge Turkish and Tatar armies were defeated.

The Croatian Nikola VII Zrinski (Miklós Zrínyi) surrounded the castle of Kanizsa, captured by Turks in 1600, at the beginning of the siege, but the Court ordered him to stop.

In 1661, he built Novi Zrin, a castle at the Mura River in Međimurje, a small region in the northernmost part of Croatia, with help of a military engineer from the Netherlands.

Grand Vizier Köprülü Ahmed Pasha set out with his nearly 80,000-strong army to conquer Royal Hungary, intending this as the first step to an attack on Vienna.

Since he did not dare to expect much from Vienna, he made an alliance with two other powerful lords and leading figures of the country, Count Franz III.

At Zrinski's suggestion, they decided to attack, and preferably as soon as possible, while the winter lasted, because at this time of year the Turks could not deploy a larger and more effective force.

The Zrinski clearly saw that Hungary and Croatia alone would not be able to stand up to the Ottoman war, which despite all its weaknesses was still very strong, but the Hungarian common people were quite averse to the issue of foreign aid.

Zrinski and the other Hungarian lords sought support from the French and Louis XIV with loyal German princes, who concluded the Rhine Alliance not only against the Turks, but also to reduce the influence of the Habsburgs in.

In the northeast, a Hungarian army led by László Rákóczi and István Barkóczy attacked Várad, not with the aim of recapturing the castle, but somehow distracting the Pasha there.

The imperial and Hungarian armies led by the French Jean-Louis de Souches and István Koháry attacked the Turks from the territory of the mining towns in the highlands.

The ranks of the latter were supplemented by a Polish brigade commanded by Marshal Jerzy Lubomirski and Captain Sepsésg, recruited by the paladin from Poland.

Two days later, Zrinski and Pál Esterházy, then chief marshal (later palatine), set off with the Croatian and Hungarian cavalry (5,000 men) on the line of the Dráva, while the infantry of their army remained with the Germans at the siege of Pécs.

It was a horrible sight when we watched this bridge, which was so many thousands of paces long, burning like a lit torch at night, like some devilish vision tearing at us"[3] While Zrinski was in Osijek, several Croatian, Austrian and Hungarian mainly infantry units from the Christian army that remained at Pécs separated from the army and headed towards the Danube-Drava estuary region.

With the destruction of the Osijek bridge, the wide Drava river separated the Hungarian and Croatian territories in Turkish hands from each other.

Von Hohenlohe called the campaign the greatest act of war in the last hundred years, and the future prospects of the battle were also encouraging.

[6] The Turkish defenders persisted, and the Grand Vizier Köprülü Ahmed Pasha hurried to relieve them at the head of his 60,000 strong army.

Meanwhile, the Ottoman Grand Vizier Köprülü Ahmed Pasha led his army against Novi Zrin, the construction of which was a casus belli in the eyes of the Porte.

Another goal of Grand Vizier Köprülü Ahmed Pasha was to break through the Rába line to march against Vienna from there, Mehmed IV by order.

However, Montecuccoli, at the head of the Austrian, German, Rhineland and French troops, defeated the Turkish army, in the Battle of Saint Gotthard Despite the victory, the Viennese court concluded the shameful Peace of Vasvár.
