"The Pursuit and Battles at Sanok and Rzeszów (May 6).—After his severe defeat, Radko Dimitriev's plan was to hold the Łupków Pass with his left wing, and, supported upon this, to bring the pursuit to a stand on the line Nowotaniec–Besko-right bank of the Wisłok, where there were positions favoured by the lay of the ground, and then, between the Vistula and the Wisłok, on the line Wielopole-Rzeszów–Mielec. Here he proposed to reconstitute his units, which had fallen into great disorder, and to strengthen them by bringing up reserves.
Troops were sent to him from other fronts, and by the 8th he could again dispose of 18 inf. divs., 5 cav. divs. and 5 Reichswehr bdes. The orders were that the offensive was to be continued with all possible vigour. Mackensen's army was to push forward over the stretch of the Wisłok between Besko and Frysztak on Mrzygłód and Tyczyn, and the Archduke Joseph Ferdinand on Rzeszów, while Boroevic was to roll up Brussilov's VIII. Russian Army in the direction of Sanok. Bohm's II. Austrian Army was to join up corps by corps from the left wing in proportion to the progress of the attack."Joly, Ernst (1922).
