In the campaign of 1760 he received command of the army destined for service in Silesia. It consisted of 40,000 men, and in all operations he was to be seconded by the Russians, who, according to an agreement made by the two Empresses, were to fight their way along the banks of the Oder, while Daun carried on the war in Saxony. This army was light, and as unencumbered by baggage as a Pandour leader could desire. At its head Loudon left the camp in which he had passed the winter, and after attacking and repulsing General Goltze at the head of his horse, he left Draskowitz with 6000 men at Neustadt, and took the road to Bohemia, after menacing in succession Silesia, into which he penetrated with two corps, the new Marche of Brandenburg, Breslau, even Berlin and Schwiednitz. At last he fixed upon the latter, and General the Baron de la Mothe Fouque (who had weakened his forces by detaching the brigades of the Scottish General Grant and General Zeithen), deceived by an artful feint, marched towards it with all his troops leaving the garrison in Glatz quite unprotected. The able Loudon at once perceived the success of his feint, or stratagem, and immediately had recourse to another. He took possession of Landshut, and left there a small body of troops, who were immediately assailed and driven out by the Baron de la Mothe. While the latter was thus occupied in recovering this trivial post, Loudon made himself master of several important positions, and passed in triumph through Johannesberg and Wisstengersdorff, and at Schwarzwalde routed the hussars of Malachowski, and thus surrounded the baron's little army of Prussians. The latter did everything requisite to secure their position against the superior force of Loudon, who early in June attacked them with irresistible fury. On the night of the 23rd he seized two heights on the right, and formed there two batteries, which swept the Prussian front and rear. He then stormed their intrenchments at the head of 28,000 men, and drove out the enemy, who formed solid squares to repel his cavalry, which pushed them in disordered masses on the Balkenhayn-road. Their squares were broken, and 4000 men were slain. Among them fell the gallant baron, pierced by two mortal wounds. Seven thousand men surrendered, and Glatz, the most important place between Silesia and Bohemia, as it stands in a narrow vale between two lofty hills, was the immediate consequence of the victory. The Gersdorff hussars and dragoons of Platen cut a passage to Breslau with 1500 of the infantry.
