In 1663, the Ottomans launched a disastrous invasion of the Habsburg Monarchy, ending at the Battle of St. Gotthard. The battle was won by the Christians, chiefly through the attack of 6,000 French troops led by La Feuillade and Coligny. The Austrians were unable to follow up on this victory due to the intervention of French forces in the Rhine; in such circumstances the Protestant allies of the Catholic Habsburgs would have proven unreliable, wanting instead to have the Austrians and themselves fight the French in a German coalition. The Ottomans therefore turned their attention north again against the Polish–Lithuanian Commonwealth. By now, the Kingdom had fallen into a terrible state; the Sejm had divided loyalties and the treasury was bankrupt. It is therefore noteworthy that John III Sobieski, king of Poland, led a decisive victory against the Ottomans at the Second battle of Khotyn.
