had promptly and energetically responded to my request, and had
sent me three regiments which were posted to protect Waterhouse's
battery and the left flank of my line.

The battle opened by the enemy's battery, in the woods to our
front, throwing shells into our camp. Taylor's and Waterhouse's
batteries promptly responded, and I then observed heavy battalions
of infantry passing obliquely to the left, across the open field in
Appler's front; also, other columns advancing directly upon my
division. Our infantry and artillery opened along the whole line,
and the battle became general. Other heavy masses of the enemy's
forces kept passing across the field to our left, and directing
their course on General Prentiss. I saw at once that the enemy
designed to pass my left flank, and fall upon Generals McClernand
and Prentiss, whose line of camps was almost parallel with the
Tennessee River, and about two miles back from it. Very soon the
sound of artillery and musketry announced that General Prentiss was
engaged; and about 9 A. M. I judged that he was falling back.
About this time Appler's regiment broke in disorder, followed by
Mungen's regiment, and the enemy pressed forward on Waterhouse's
battery thereby exposed.

The three Illinois regiments in immediate support of this battery
stood for some time; but the enemy's advance was so vigorous, and
the fire so severe, that when Colonel Raith, of the Forty-third
Illinois, received a severe wound and fell from his horse, his
regiment and the others manifested disorder, and the enemy got
possession of three guns of this (Waterhouse's) battery. Although
our left was thus turned, and the enemy was pressing our whole
line, I deemed Shiloh so important, that I remained by it and
renewed my orders to Colonels McDowell and Buckland to hold their
ground; and we did hold these positions until about 10 a.m., when
the enemy had got his artillery to the rear of our left flank and
some change became absolutely necessary. Two regiments of
Hildebrand's brigade--Appler's and Mungen's--had already
disappeared to the rear, and Hildebrand's own regiment was in
disorder. I therefore gave orders for Taylor's battery--still at
Shiloh--to fall back as far as the Purdy and Hamburg road, and for
McDowell and Buckland to adopt that road as their new line. I rode
across the angle and met Behr's battery at the cross-roads, and
ordered it immediately to come into battery, action right
