ad been in command of the Second Corps,
since yesterday, but Gen. Hancock, relieved of his duties elsewhere, now
assumed command. Five or six hundred yards away the Third Corps was
making its last opposition; and the enemy was hotly pressing his
advantages there, and throwing in fresh troops whose line extended still
more along our front, when Generals Hancock and Gibbon rode along the
lines of their troops; and at once cheer after cheer--not Rebel, mongrel
cries, but genuine cheers--rang out all along the line, above the roar
of battle, for "Hancock" and "Gibbon," and "our Generals." These were
good. Had you heard their voices, you would have known these men would
fight. Just at this time we saw another thing that made us glad:--we
looked to our rear, and there, and all up the hillside which was the
rear of the Third Corps before it went forward, were rapidly advancing
large bodies of men from the extreme right of our line of battle, coming
to the support of the part now so hotly pressed. There was the whole
Twelfth Corps, with the exception of about one brigade, that is, the
larger portion of the Divisions of Gens. Williams and Geary; the Third
Division of the First Corps, Gen. Doubleday; and some other brigades
from the same Corps--and some of them were moving at the double quick.
They formed lines of battle at the foot of the Taneytown road, and when
the broken fragments of the Third Corps were swarming by them towards
the rear, without halting or wavering they came sweeping up, and with
glorious old cheers, under fire, took their places on the crest in line
of battle to the left of the Second Corps. Now Sickles' blunder is
repaired. Now, Rebel chief, hurl forward your howling lines and columns!
Yell out your loudest and your last, for many of your best will never
yell, or wave the spurious flag again!

The battle still rages all along the left, where the Fifth Corps is, and
the West slope of Round Top is the scene of the conflict; and nearer us
there was but short abatement, as the last of the Third Corps retired
from the field, for the enemy is flushed with his success. He has been
throwing forward brigade after brigade, and Division after Division,
since the battle began, and his advancing line now extends almost as far
to our right as the right of the Second Division of the Second Corps.
The whole slope in our front is full of them; and in various formation,
in line, in column, and in masses which are neither, wi
