as he was sitting under a tree watching his troops.

Gregg, one of the best of the Southern generals, was mortally wounded.
A great body of the Pennsylvanians, charging again, reached the shelter
of the woods and burst through the Southern line. At another point,
Hancock, always cool and brilliant on the field of battle, rallied
shattered brigades and led them forward in person to new attacks.
Hooker, who had shown such courage at Antietam, equally brave on this
occasion, rushed forward with his men at another point. Franklin,
Sumner, Doubleday and many other of the best Union generals showed
themselves reckless of death, cheering on their men, galloping up and
down the lines when they were mounted, and waving their swords aloft
after their horses were killed, but always leading.

The Pennsylvanians who had cut into the Southern line were attacked in
flank, but they held on to their positions. Jackson did not yet know
of Meade's success. He still stood on Prospect Hill with his staff,
which Harry had rejoined. The forest and vast clouds of smoke hid from
his view the battle, save in his front. Harry saw a messenger coming at
a gallop toward the summit of the hill, and he knew by his pale face and
bloodshot eyes that he brought bad news.

Jackson turned toward the messenger, expectant but calm.

"What is it?" he asked.

"The enemy have broken through General Archer's division, and he
directed me to say to you that unless help is sent, both his position
and that of General Gregg will be lost."
