THREE:The seventh campaign of the Seven Years�� War commenced on the 1st of July, 1762. Peter III. had sent an army of twenty thousand men to the support of Frederick. Aided by these troops, united with his own army, Frederick had emerged from532 his winter quarters, and was just about to attack the Austrian army, which was intrenched upon the heights of Burkersdorf, a little south of Schweidnitz, which fortress the Austrians then held. The evening before the contemplated attack the Russian General Czernichef entered the tent of Frederick with the following appalling tidings:General Neipperg had advanced as far as Baumgarten when283 he heard of this entire circumvention of his plans. Exasperated by the discomfiture, he pushed boldly forward to seize Schweidnitz, where Frederick had a large magazine, which was supposed not to be very strongly protected. But the vigilant Frederick here again thwarted the Austrian general. Either anticipating the movement, or receiving immediate information of it, he had thrown out some strong columns to Reichenbach, where they so effectually intrenched themselves as to bar, beyond all hope of passage, the road to Schweidnitz. General Neipperg had advanced but half a day��s march from Baumgarten when he heard of this. He ordered a halt, and retraced his steps as far as Frankenstein, where he had a very strongly intrenched camp.
