After Loudon entered Silesia in August, some severe fighting ensued, especially at Munsterberg, and on the hills of Labedau. Lacy was then hovering with his troops near Grossenhayn, and encamping at Gros-dobritz, from whence he advanced his videttes as far as Strehlen along the Elbe--for Count O'Donnel still occupied Dresden or its neighbourhood.
In September, Lacy was sent with his brigade, 15,000 strong, by Daun, to join the Russians at Brandenburg, with orders to ravage all the electorate, which, while covered by the army of Soltikoff, he did so effectually as to compel Frederick either to shift his camp from Buntzelwitz, on which he had 466 guns with 182 mines, or to weaken his army by sending out detachments to protect the burning country. In doing the latter some of Prince Henry's cavalry were severely cut up by Lacy's dragoons in a forest near Reisa; and to avoid such unpleasant surprises in future, the Prussians cut down all the magnificent timber that surrounded the old castle of Hubertsbourg; but on Lacy's nearer approach they retired to Potsdam and Spandau. In October, Prince Henry of Prussia and Marshal Daun were both encamped--one under the walls of Dresden, and the other under the ramparts of Meissen, while their hussars and light troops fought together hourly, and Lacy hovered in the neighbourhood of Lusace, watching some large detachments of Prussians.
In December he again terrified the inhabitants of the capital by appearing suddenly within seven miles of Berlin; but on an overwhelming force under General Bandemer being sent against him by Prince Henry, he recrossed the Elbe and retreated.
Fortunately in 1762 there was concluded with the Court of Vienna a cessation of hostilities for the provinces of Saxony and Silesia. This partial truce induced the Princes of the Empire to sign a treaty of neutrality to save their petty dominions from the ravages of Frederick; and as Sweden and Russia, on the accession of the Czar Peter III, had concluded a truce with him, the Septennial War was thus left to be finished by the two powers which began it--Prussia and Austria.
In that year the Khan of the Crimea proposed to join the former, and indeed marched 5000 men towards the frontier of Poland for that purpose; but the death of the Czarina Elizabeth, and the consequent revolution in Russia, had so bewildered the poor Tartar, that not knowing what side to take, he timidly retreated to Perekop. On this Frederick recalled the Prince of Bavern from Moravia, with his troops, that together they might make doubly sure of Schweidnitz.
