By the end of the day on July 12 it was becoming clear that II SS Panzer Corps' attempt to take Prokhorovka had failed; Hitler would order Operation Citadel to cease the following day. In order to salvage something from the wreckage he authorized Field Marshal E. von Manstein's hastily-developed plan for Operation Roland, which would link up the SS Corps with III Panzer Corps to encircle and destroy at least the 48th Rifle Corps, if not all of 69th Army. The German forces spent most of July 13 regrouping for this new effort; however the III Panzers probed the Soviet defenses with strong reconnaissance forces and launched holding attacks from the area of Rzhavets. During the day the 89th Guards and one battalion of the 375th Rifle Division were subordinated to Maj. Gen. I. K. Morozov, the commander of the 81st Guards, in an effort to create a Corps reserve. A few hours later Morozov issued a formal rebuke to the chief of staff of the division for ordering the 267th Guards Regiment to fall back without his authorization, and the Regiment returned to its previous positions.
