Editing Fort Donelson (section)

==History==
[[Bushrod Johnson]] of the Confederate Corps of Engineers had approved the build site and supervised construction completed in early 1862.  The site commanded a bend on the west side of the Cumberland River, It was planned to support [[Battle of Fort Henry#Fort Henry|Fort Henry]], which is located on a bend in the Tennessee River about 10 miles to the west.<!--Still confusing description - where is it in relation to confluence?  -->  To the north flows Hickman River, a backwater channel that was impassable except by boat or bridge,<ref>{{cite book |last1=Hurst |first1=Jack |title=Men of Fire |date=2007 |publisher=Basic Books |location=Philadelphia, PA |isbn=978-0-465-03185-6 |page=190}}</ref> and to the east a small tributary named Indian Creek enters the Cumberland.  The fort, which was intended to house troops and protect the water batteries from sorties, had a few acres of log huts.  

Like Fort Henry, which fell to Union troops on February 6, Fort Donelson would not be able to defeat a large-scale assault, but officers wanted to be able hold the position as long as possible.  Engineers began improving defensive positions by digging rifle pits along a ridgeline and breastworks were built in "a three-mile arc which inclosed {{sic}} the bluff on the north, and the county seat hamlet of Dover on the south, the main supply base."<ref>{{cite book |last1=Foote |first1=Shelby |title=The Civil War: A Narrative Vol.1 |date=1986 |publisher=Random House |location=New York |isbn=0-394-74623-6 |page=[https://archive.org/details/civilwarnarrativ00foot/page/194 194] |url=https://archive.org/details/civilwarnarrativ00foot |url-access=registration }}</ref>  Cannons, including a 128-pounder and two 32-pounders, were placed atop the hundred-foot bluff within the arc.  Construction was started by a large force of workers brought from the nearby Cumberland Iron Works.

Fort Donelson was garrisoned by the Confederate troops until 1862. The fort was captured by Union General [[Ulysses S. Grant]] and his army during a winter offensive to control of the Mississippi River. Grant believed that such control would enable him to divide the Confederacy in two. (see [[Battle of Fort Donelson]])

On August 25, 1863, a Confederate force attacked the fort and demanded surrender by Union troops. Their attack was unsuccessful and was repulsed by the Union garrison.

Fort Donelson was attacked by General U.S Grant and Flag Officer [[Andrew Foote]], who surrounded the fort and captured it after a short siege. On February 6, Grant was ordered by General [[Henry Halleck]] to assault Fort Donelson immediately and capture it by February 8.  Grant made reconnaissance, observed the natural obstacles and Confederate improvements, and knew the fort would not be taken by the 8th.  He organized and had Brigadier Generals [[John A. McClernand]], [[Charles Ferguson Smith|Charles F. Smith]], and [[Lew Wallace]] prepare for a land assault while Flag Officer Foote moved his gunboats to assault from the river.  After minor skirmishes with Confederate cavalry en route, the assault on Fort Donelson began on February 12.  On February 14, a naval battle took place, in which Union ships suffered serious damage.  After attempting in vain to escape their tenuous position on February 15 via roads to Nashville, the Confederates capitulated, surrendering Fort Donelson to the Union on February 16.<ref>{{cite book|last1=Hamilton|first1=James|title=The Battle of Fort Donelson|date=1968|publisher=Thomas Yoseloff Ltd.|location=Cranbury, NJ|OCLC=2579774}}</ref>

The Union was ecstatic when the news of Fort Donelson's surrender reached the capital and cities. Union forces now controlled one of the largest forts in the western theater. The war had been going badly for the Union in Virginia, but the captures of Fort Henry and Fort Donelson were promising victories.

After the front line shifted away from Fort Donelson, it became of little strategic importance, but continued to hold a garrison of Union troops. Later, the fort was attacked by a Confederate force of 450 infantrymen, 335 cavalrymen, and two field guns. The Union garrison consisted of four companies (404 men) of the 71st Ohio Regiment.  After suffering 30 casualties, the Confederates retreated. They were pursued by the Fifth Iowa Cavalry, but to no avail.

* [[William W. Lowe]] (Feb 1863)
