<P> In France, 1758 had been disappointing, and in the wake of this a new chief minister, the Duc de Choiseul, was appointed . Choiseul planned to end the war in 1759 by making strong attacks on Britain and Hanover . </P> <P> The year 1759 saw several Prussian defeats . At the Battle of Kay, or Paltzig, the Russian Count Saltykov with 47,000 Russians defeated 26,000 Prussians commanded by General Carl Heinrich von Wedel . Though the Hanoverians defeated an army of 60,000 French at Minden, Austrian general Daun forced the surrender of an entire Prussian corps of 13,000 in the Battle of Maxen . Frederick himself lost half his army in the Battle of Kunersdorf (now Kunowice Poland), the worst defeat in his military career and one that drove him to the brink of abdication and thoughts of suicide . The disaster resulted partly from his misjudgment of the Russians, who had already demonstrated their strength at Zorndorf and at Gross - Jägersdorf (now Motornoye, Russia), and partly from good cooperation between the Russian and Austrian forces . </P> <P> The French planned to invade the British Isles during 1759 by accumulating troops near the mouth of the Loire and concentrating their Brest and Toulon fleets . However, two sea defeats prevented this . In August, the Mediterranean fleet under Jean - François de La Clue - Sabran was scattered by a larger British fleet under Edward Boscawen at the Battle of Lagos . In the Battle of Quiberon Bay on 20 November, the British admiral Edward Hawke with 23 ships of the line caught the French Brest fleet with 21 ships of the line under Marshal de Conflans and sank, captured, or forced many of them aground, putting an end to the French plans . </P> <P> The year 1760 brought yet more Prussian disasters . The general Fouqué was defeated by the Austrians in the Battle of Landshut . The French captured Marburg, and the Swedes part of Pomerania . The Hanoverians were victorious over the French at the Battle of Warburg, their continued success preventing France from sending troops to aid the Austrians against Prussia in the east . </P>
