He made an attack on General Seidlitz near Frederick's strong camp at Schmuckseiffen, and lost 150 men. Immediately after this, the Court of Vienna gave him command of 20,000 men, 1200 of whom were dragoons, to give vigour to their Russian allies, who were destitute of cavalry. By the way of Greiffenberg he marched through Silesia, foiling, deceiving, and skirmishing with the horse of Prince Henry, till he took up a position on the heights of Laubau, where he had fought the Prussians in the preceding year. He chose this ground with the intention of being in advance of them now, when he should receive orders to join the Russians under Count Soltikow. With this general he achieved a junction, and together they took up a position at Cunnersdorff, opposite Frankfort-on-the-Oder, and gave battle to Frederick at eleven o'clock, A.M., on the 12th of August. The Russians had their intrenchments stormed amid great slaughter; a starfort erected by them on two sand hills, to cover their right flank, was carried at the point of the bayonet, and a dreadful massacre of them ensued in the churchyard of Cunnersdorff. Under the glare of a burning sun, and sore with many a wound, the brave King of Prussia led on his troops; and for two hours the infantry fought hand to hand. The Jews' Cemetery, seven redoubts, and 180 pieces of cannon, were already taken, when Loudon, perceiving that the Russians were unable to maintain their ground, brought up his well-chosen reserves, and fired his field-pieces loaded with case-shot, to sweep the Prussian line. He then charged on both flanks with his fine Austrian cavalry, who bore down all before them. The Prussians fell into confusion, and their rout became total. Frederick had two horses shot under him, and his blue uniform literally torn to rags by bullets and sword-cuts. The struggle was awful, and night came down on a field where 30,000 men lay dead or dying, and of these more than the half were Prussians. The brave Putkammer was slain, and ten other generals lay killed or wounded near him. The movements of Frederick after this most signal defeat were of a masterly description. He soon compelled Loudon and Soltikow to act on the defensive, and recovered every place in the Saxon Electorate except Dresden. Forcing the Russians to retire into Poland, he joined his brother Prince Henry in Saxony, compelled Marshal Daun to retreat as far as Plawen, and forced him to take shelter in the camp at Pirna; after which he retired into winter quarters in November. For his victory at Cunnersdorff Loudon was raised to the rank of _General-velt-zeug-Meister_; but he drew off from Soltikow with all his cavalry immediately after the battle.
