Then the horse uttered a terrible neighing cry, but Harry, alert and agile, sprang clear, and ran back to his own command.
On the other side of Bull Run was the Northern command of Tyler, which had been rebuffed so fiercely three days before.

It, too, heard the roar and crash of the battle, and sought a way across Bull Run, but for a time could find none.

An officer named Sherman, also destined for a mighty fame, saw a Confederate trooper riding across the river further down, and instantly the whole command charged at the ford.

It was defended by only two hundred Southern skirmishers whom they brushed out of the way.

They were across in a few minutes, and then they advanced on a run to swell McDowell's army.
