 Lee received Magruder 's calls for reinforcement and instructed Huger to let Ransom go support the men trapped on the field of battle . He also sent orders to the brigades of Brig. Gens . Joseph B. Kershaw and Paul Jones Semmes , in Maj. Gen. Lafayette McLaws 's division within Magruder 's command . Robert Ransom 's unit , after they finally showed up with Huger 's permission , first attempted to charge straight up the hill , following the path of other Confederate brigades attempting to aid Magruder . When this proved useless , Ransom ordered them to regroup in the woods to the Confederate right , march double @-@ time a half a mile in a hook to the right around all the other Confederate units and attack the far Union western flank . While Ransom was angling west , Jackson responded to a request for reinforcement from D. H. Hill by sending forward brigades from his own command to move from the east into the area where D. H. Hill had attacked . From his own division Jackson sent Brig. Gens . Alexander Lawton and Charles S. Winder , and from Ewell 's division , Brig. Gen. Isaac R. Trimble and Cols . Leroy A. Stafford and Jubal Early .
