Early's force had gained a position opposite West Fort on Apple Pie Ridge. Eight guns were positioned on the Brierly Farm northwest of the fort, while 12 guns were placed in an orchard southwest of the fort, but by this time the field had quieted. Within the Federal forts, Milroy and his sub-commanders believed that the Confederates had been repulsed from Winchester, still seemingly unaware they were now totally surrounded and cut off, with the additional problem of an entire division (Rodes') occupying their primary escape route north. Early's attack on West Fort About 6 p.m., Early's artillery opened fire on West Fort. The twenty guns fired for 45 minutes, while Hays stealthily advanced his Louisiana brigade through the corn and wheat fields at the base of Apple Pie Ridge. On command, the brigade rushed forward across 300 yards of open fields and swept upward into the works. After a brief hand-to-hand struggle, the Federal defenders abandoned the works, retreating to Fort Milroy, while their own captured artillery were turned around and used against them. Hays was supported in the attack by Smith's and Avery's brigade, and Early consolidated his line on West Fort (or Flint) Ridge, but darkness prevented further gains. An artillery duel continued until long after dark. After the battle, Ewell christened West Fort Ridge as "Louisiana Heights" in honor of Hays's brigade. That evening, Ewell located his Corps Headquarters at the Bowers' House, while Early's Division pounded away at Milroy's main fort in an artillery duel well into the night. Johnson's right flanking march toward Stephenson's Depot Ewell assumed that Milroy might attempt a retreat during the night and ordered Johnson to prevent his escape by marching north and cutting off escape to the east-north-east via the Charles Town Road, a potential escape route that could possibly bypass the position of Rodes' Division in the north. Therefore, about 9 p.m., Johnson (with Steuart's and Williams's brigades and 8 guns) commenced a night march north to Berryville Pike and west to Jordan Springs Road, where he turned north toward Stephenson's Depot, a train stop on the Winchester and Potomac Railroad near the intersection of the Martinsburg Pike and the Charles Town Road. About midnight, the Stonewall Brigade disengaged and joined the rear of the column, leaving one brigade (Jones) astride the Berryville Pike east of town. Milroy retreats up the Martinsburg Pike Also at 9 p.m., at
