11. Armee
The Central Powers next objective was a continued advance towards the east from a bridgehead at Magierów, and the ultimate recapture of Lemberg, which would sever lines of communication between the Russian Northwest and Southwest Fronts. Mackensen would not only command his Eleventh Army but also the Austro-Hungarian Fourth Army, augmented with the X and XVII Corps, on his northern flank, and the Austro-Hungarian Second Army, augmented with the "Beskidenkorps", on his southern flank. The Eleventh Army Order of battle, north to south, consisted of Karl von Behr's Corps, Emmich's X Corps, Eugen von Falkenhayn's XXII Reserve Corps, Plettenberg's Guards Corps, Arz's Austro-Hungarian VI Corps, and François' XLI Reserve Corps.
