During the War Between the States, D.N. McIntosh organized a regiment
and joined the Confederate States Army as a colonel. He was notable for
recruiting and organizing the 1st Creek Mounted Volunteers and for
leading them in several battles in Indian Territory. After the war, he
continued as a farmer and rancher.

After his father was executed
by order of the Creek National Council in 1825 for having ceded communal
Creek territory to the United States in violation of tribal law, the
surviving members of the family moved to Indian Territory in 1828, where
they settled on the Verdigris River. They established what was known as
the Western Creek Nation for some time. Daniel was sent back East to be
educated at Smith's Institute in Kentucky until 1841. D. N. later
moved to a site near the community of Fame, in what is now McIntosh
County, Oklahoma. He developed a farm and also raised cattle. He was
also a Baptist preacher.

At the outbreak of the War Between the
States, Daniel N. McIntosh organized and served as a Colonel of the 1st
Creek Mounted Volunteers (later known as the First Creek Cavalry
Regiment, C.S.A.). Daniel's elder brother, Chilly McIntosh, organized
and served as a Colonel of the 2nd Creek Mounted Volunteers (later known
as the Second Creek Cavalry Regiment, C.S.A.) which was under the
administrative command of Daniel N. McIntosh. D.N. McIntosh was
organizing the 3rd Creek Cavalry Regiment, C.S.A., which would have
entitled him to the rank of Brigadier General in the Confederate Army.
But the war ended before he received that rank. Eight members of the
McIntosh family served in Colonel McIntosh's regiment.

His
regiment fought in the following battles: Round Mountain, Chusto-Talasah
(Shoal Creek), Chustenahlah, Pea Ridge, Old Fort Wayne, Honey Springs
and Cabin Creek. Colonel McIntosh's Regiment was one of General Stand
Watie's units having the distinction of being one of the last
Confederate military units to surrender to Union military forces on 23
June 1865 near Doaksville, Choctaw Nation, Indian Territory.
