its too bad Lee couldent have dropped a note with his plans that would have to Lee netting the 12000 bluecoats like fish in a barrel. any ways....the out come after all was, indeed, not in favor of the Union Army. lets read on and see how so did the C.S.A . keep in mind that Lee and McClellan served togeather during the 1848 Mexican War, thus knowing each other well. McClellan made careful plans and didnot order the men forward untill daylight on sept. 14, eighteen hrs. after he had learned of Lee's dispositions.as things turned out,this delay enabled Lee to concentrate and save his army. a pro-confederate citizen of Maryland had witnessed McClellan's responce to the finding of the lost orders and had ridden hard to inform Stuart, who passed the info. along to Lee on the night of sept. 13.Lee orderd troops to block the passes through South Mountain.next day 2 Union corps fought up-hill against D.H.Hill's Confederate division defending Turner's Gap.taking heavy losses,Hill's hardy band hung on behind stone walls and trees untill Longstreet came up with reinforcements and held off the Federals untill night fall.withdrawing after dark,these out-numbered rebals had given Lee an extra day.meanwhile another Union corps under William B.Franklin had smashed through Crampton's Gap 6 miles to the south after a sharp fire-fight with 3 Confederate brigades.despite great numerical superiority,Franklin advanced timidly southward toward the forces besieging Harper's Ferry and failed to arrive in time to save the Union garrison at the Ferry!
