The Turks have arranged for the election of Mihály Apafi as prince.

Kemény, initially supported by Imperial general Raimondo Montecuccoli, returns to Transylvania in early September.

The Austrian army soon deserts him, however.

The Turkish army, having wintered in Belgrade, renews its advance on Austrian Hungary, taking as many fortresses as possible on the road to Vienna and causing the Austrians under Holy Roman Emperor Leopold 1 (1640-1705) to begin peace negotiations.

Before ratifying the peace terms, the Turks plan to hold the area north of the Raab River, but fortune and bad weather rule otherwise.

Half of the Turkish army has crossed the river in the area of the Convent of St. Gotthard, but rain and flooding prevent the second half from crossing.

Austrian cavalry under Field Marshal Raimund Montecuccoli (1609-80) defeat the advance force in the Battle of St. Gotthard (or Raab River) on August 1, 1664, for which Montecuccoli is hailed as the savior of Christendom.

The Battle of St. Gotthard, the first great Turkish defeat, has forced the Treaty of Vasvár, a twenty-year truce signed on August 10, which confirms Turkish suzerainty over Transylvania but removes Austrian and Ottoman troops from the area to reduce confrontation.

In a minor territorial concession, the Turks keep the fortresses they have seized.

The Austrian military success is not reflected in the terms of the Treaty of Vasvar, as Transylvania is given to Apafi as an Ottoman client prince.

Raimondo Montecuccoli, the long-serving field marshal of the imperial army, had opposed the progress of the French arms under Louis XIV, and when the inevitable war broke out he had received command of the imperial forces.

Montecuccoli and the Frederick William Hohenzolloern, the Great Elector of Brandenburg, assemble at Halberstadt in October 1672 to attack the French and the bishops of Munster and Cologne in their rear.

Galen's army has become stuck before the city of Groningen, failing to occupy the coast in the North, because of the purposeful inundation of the fields and marshes that are almost impossible to cross.

He withdraws slowly to the south.

William takes his army to Maastricht in November 1672 to threaten the French supply lines.

Dutch troops commanded by Montecuccoli and Prince William III of Orange on November 13, 1673, conquer Bonn, the seat of the Archdiocese of Cologne.
