We must dismount, leaving one man in every ten to hold the horses, signal to Colonel Talbot that help has come, and then attack on foot." A bugler advanced on horseback at Stuart's command, blew a long and thrilling call, and then another man beside him broke out an immense Confederate flag.
"They see us in the fort and recognize us," said Stuart.

"Hark to the cheer!" The faint sound of many voices in unison came up from the valley, and Harry knew it to be the Invincibles expressing joy that help had come.

The fort then opened with its own guns, and Stuart's dismounted horsemen, who were armed with carbines, advanced through the forest, using the trees for shelter, and attacking the Northern force on the flank.

They and the Invincibles together were not strong enough to drive off the enemy, but the heavy skirmishing lasted until the middle of the afternoon, when a whole brigade of infantry came up from the main army.

Then the Northern troops retreated slowly and defiantly, carrying with them all their wounded and every gun.
"I've got to take my hat off to the mill hands and mechanics," said St.Clair.
