Early on the morning of October 9, the Confederates broke camp to try to move unnoticed around Meade's flank. They avoided hills and dusty roads where marching might raise clouds of dust that could be seen for miles. Lee knew that if Meade discovered his movements he would either commit to battle or move north of the Rappahannock. But Union pickets reported there were no drum or bugle calls and no smoke from the morning cooking fires coming from the Confederate camps. Word was sent to Meade's headquarters that the rebel army seemed to be moving westward. Meade still did not know what was happening but was very uneasy about these reports. Lee might be moving south to Richmond or he could be moving north trying to turn Meade's flank. Meade also realized that Lincoln was unhappy with his letting Lee escape after Gettysburg. So Meade knew he had to do something.
