noon
The remainder of the ninth of September passed . The tenth of September passed , and the eleventh , mild , balmy and extremely still . The twelfth found the landscape for miles around Frederick still dozing . At noon , however , upon this day things changed . McClellan 's strong cavalry advance came into touch with Jeb Stuart a league or two to the east . There ensued a skirmish approaching in dignity to an engagement . Finally the grey drew off , though not , to the Federal surprise , in the direction of Frederick .
