Yorck’s van – a combined-arms detachment commanded by Lobenthal – spearheaded the drive into the neutral zone. Departing from Lorzendorf (Wawrzeńczyce), the Prussians marched almost twenty miles northwest to secure Mertschütz, itself halfway to Liegnitz. From Panzkau (Pęczków), one cavalry detachment under Major Schenk consisting of two squadrons each from the 2nd Leib Hussars and the Brandenburg Hussars established communication with Sacken’s corps. Yorck’s main body trooped to Saarau and Konradswaldau (Mrowiny) in three columns. For added security, the Prussian corps commander kept the cavalry of each of his four brigades close to the infantry. To the left of the Prussians, Langeron’s vanguard reached Jauer; the main body halted ten miles to its southeast at Striegau, itself four miles west of Yorck’s main body. Two hundred Cossacks maintained communication between Yorck’s and Langeron’s vanguards. On Blücher’s right, Sacken’s corps marched into Breslau but did not achieve its objectives of Neumarkt and Deutschlissa. After occupying the provincial capital, the Russian corps commander continued only to Breslau’s western suburbs instead of the Schweidnitz stream. He pushed six Cossack regiments to Deutschlissa rather than Neumarkt. Purportedly, Sacken admitted to purposefully deviating from the disposition. On Blücher’s extreme left wing, Kaysarov led Pahlen III’s van of four Jäger battalions and three Cossack regiments only to Schmiedeberg, likewise falling short of his objective of reaching Hirschberg. Blücher’s headquarters moved to Würben, four miles north of Schweidnitz (see Map 2).
