Meanwhile the siege of Münster had gone ill for the Allies, and had been turned into a blockade. Ferdinand, after sending additional troops thither, found himself too weak to attempt further operations until the fall of the town; and during this interval Broglie, who had been appointed to the supreme command, had received a reinforcement of ten thousand Würtembergers. Thus strengthened he tried incessantly with a detached corps of twenty thousand men to interrupt Ferdinand's communications with Cassel, but in vain; and finally the Hereditary Prince attacked this corps at Fulda, defeated it signally, and then turning upon Broglie's right flank forced him to retire to Friedberg. Ferdinand then blockaded Giessen; but at this point further operations were stayed. Ever since his disastrous defeat by the Russians at Kunersdorf in August, Frederick the Great had pressed Ferdinand for reinforcements; and the detachment of twelve thousand troops to the King not only rendered the Prince powerless for further aggression, but obliged him also to raise the blockade of Giessen. In January 1760 both armies retired into winter-quarters. The French occupied much the same ground as at the beginning of the campaign; and the Allies likewise were distributed into two divisions, the army of Westphalia extending from Münster through Paderborn to the Weser, the army of Hesse from Marburg eastward to the Werra. Thus ended the campaign of 1759, leaving both parties in occupation of the same territory as at its beginning; but it had branded the French with the discredit of a great defeat, and had heightened in the Allies their contempt for their enemy and their confidence in their chief.
