And I got that information from a cousin I've never even met, who lives in Canada!
I may not find anymore personal info than what you have, but I'll be glad to try if you don't mind to share his name.
MINNESOTA
FIRST CAVALRY
(One Year)
First Cavalry.--Col., Samuel McPhaill; Lieut.-Col.,
William Pfaender; Majs., John H. Parker, Solomon S. Buell,
Orrin T. Hayes. This regiment was made up of twelve companies,
organized in the fall of 1862 and was composed largely of men
who had lost their wives, children or relatives in the Sioux
massacre the previous August and September. The first
battalion of three companies was sent out as soon as organized
for guard and patrol duty. In the spring of 1863 nine
companies under Col. McPhaill assembled at Camp Pope for the
campaign of the Missouri, the other three companies remaining
for patrol duty. The regiment was in the battle of Big Mound,
where the 1st battalion led the attack. It fought its way up
the steep hill, put the Indians to flight and followed them for
15 miles. The regiment was in the battle of Dead Buffalo lake,
and was at Stony lake, when the Indians attacked in great
force. It reached the Missouri July 29, and returned to Fort
Abercrombie. Col. McPhaill, with several companies of cavalry,
was sent to Fort Ridgely, which place he reached Sept. 1. The
1st battalion was sent to Fort Ripley and the various companies
of the 1st cavalry were mustered out during the fall and winter
of 1863-64.

Report of Col. Samuel McPhaill, First Minnesota Mounted Rangers.
IN CAMP ON THE PLAINS, August 5, 1863.
GEN.: On the 24th of July, 1863, pursuant to your order to recover the body
of Dr. J. S. Weiser, surgeon First Minnesota Mounted Rangers, murdered by
the Indians, I proceeded to the hills in rear of Camp Sibley with Companies
A and D, of my regiment. When some 500 yards from camp, we were fired upon
by the Indians occupying the summit of the hill. I immediately ordered
Company A, under Capt. E. M. Wilson, to advance and fire upon the enemy,
which was done in good style. The ground being rocky and broken, Companies
A, D, and E were ordered to dismount and skirmish the hills, Companies B
and F, under major [O. T.] Hayes, and Company L, under Capt. [P. B.] Davy,
to support them. The First Battalion, under Maj. [J. H.] Parker, cleared
the hills and drove the Indians some 2 miles, followed by Companies B and
F, mounted. Here I met Lieut. Col. W. R. Marshall, Seventh Minnesota
Volunteers, and requested him to protect my right flank, which he did in
gallant style. Maj. Parker was then ordered to rally the companies of his
battalion and prepare to engage the enemy, mounted. I then moved forward of
the Skirmishers with Companies B and F, and ordered a charge upon the
enemy posted on the highest peak of the range known as the "Big Hills."
This order was promptly obeyed, and the Indians dislodged from their
position and driven toward the plains
west of the hills. While descending the hills, I ordered another charge
by Company B, under Capt. [Horace] Austin. While in the act of
carrying out this order, 1 man was instantly killed by lightning and
another seriously injured. This occasioned a momentary confusion;
order, however, was soon restored, and we pushed the enemy from their
positions on the hills and in the ravines in our front to the plains below.
I then ordered a rally. Companies A, B, F, and L assembled, and we
pushed forward upon the Indians, who has taken refuge behind a few
rude and hastily constructed intrenchments in their encampments, from
which they were quickly dislodged, and a running fight commenced. At
this juncture, Lieut. J.[C.] Whipple, Third Minnesota Battery,
reached us with one 6-pounder, his horses entirely given out, in
consequence of which he could only give the fleeing enemy two shots,
which apparently threw them in still greater confusion. I then again
ordered the charge, which was kept up until we had reached at least 15
miles from the first point of attack, and during which we drove them
from their concealment in the rushes and wild rice of Dead Buffalo Lake
by a well-directed volley from the deadly carbines, ran into their lines
five times, concealment in the rushes and wild rice of Dead Buffalo
Lake by a well-directed volley from the deadly carbines, ran into their
lines five times, continuing the fight till nearly dark, when Companies
H, D, and G arrived, and I received your order to return to Camp
Sibley, at the Big Hills; and some time having been consumed in
collecting our wounded and providing transportation for them, we
attempted to return, and only succeeded in reaching camp at 5 a. m. on
the morning of the 25th, having in the darkness been unable to preserve
our course, and having been in the saddle twenty-four hours without
guide, provisions, or water. The number of Indians engaged could not
have been less than 1,000, and would doubtless reach 1,500 warriors.
The losses of my regiment, including a skirmish on Sunday evening,
the 26th, at Dead Buffalo Lake, are as follows:*
Dr. J. S. Weiser, surgeon, and Lieut. A. Freeman, Company D,
were murdered by the Indians.
The number of Indians known to have been killed by the Mounted Rangers is
31, all found with the peculiar mark of cavalry upon them. Doubtless many
more were killed by the Rangers, as the wounded concealed themselves in
the marshes, where it was impossible to follow them with cavalry.
In this report I esteem in a duty, and it affords me great pleasure, to say
of the officers and men under my command who were engaged in this series of
fights and hand-to-hand encounters, that, without exception, the utmost
coolness and bravery was displayed, the only difficulty I encountered being
that of restraining the wild enthusiasm of the troops during the succession
of cavalry charges, and I can only say of them further that they have won
for themselves a reputation of which veteran troops might well be proud.
It is also a duty and gratification to mention favorably the name of First
Lieut. E. A. Goodell, acting adjutant, whose aid in the hottest of
the fight rendered me great service; also the name of John Martin, of
Company F, who bore dispatches with certainty, celerity, and security.
I am, general, very respectfully, your obedient servant,
SAM. McPHAILL,
Col., Cmdg. Mounted Rangers.
Brig. Gen. H. H. SIBLEY,
Cmdg. Expeditionary Force.
