This organizing Union infantry was recruited from the counties along the Ohio, Kanawha and Little Kanawha rivers and their tributaries. During this recruiting phase, it was first attached to the District of the Kanawha, West Virginia, to May, 1862. It was transferred to the 4th Brigade, Kanawha Division, West Virginia, to September, 1862. Next, it was reassigned to the District of the Kanawha, West Virginia, Dept. of the Ohio, to January, 1863. The 9th was assigned to Milroy's Command, Winchester, Va., 8th Army Corps, Middle Department, to February, 1863. Its following command was under the 2nd Brigade, 2nd Division, 8th Army Corps, to June, 1863. After this, the 9th was assigned to its home region to the 1st Brigade, Scammon's Division, West Virginia, to August, 1863. Change in command structure led the 9th Infantry to its home area command of the 2nd Brigade, Scammon's Division, West Virginia, to December, 1863. As West Virginia was now recognized as a state, the 9th was assigned to the 2nd Brigade, 3rd Division, West Virginia, to April, 1864. The 9th Infantry's last command assignment was the 2nd Brigade, 2nd Infantry Division, West Virginia, to November, 1864.
From November to July, 1861, the recruits were assigned to garrison duty in the Kanawha Valley with detachments at Fayette, Gauley Bridge, Summersville, Point Pleasant, Coalsmouth and Calhoun until July, 1862. Some companies scouted in Roane and Clay Counties from May 8th to the 21st. Companies "A" and "F" saw action at Summersville on July 25th. They moved over to Flat Top Mountain on July 28th and then to the battles at Summersville and Gauley August 14th. The Union had ordered 5,000 troops away from the Kanawha region to Virginia which led to the Second Battle of Bull Run. Albert G. Jenkins and his 550 Confederate Cavalry took advantage of this weakening in the region. They took control of the towns from Monroe County to Jackson County and raided from there into Ohio during the month of August, 1862. Some claim it was a diversion tactic.
Meanwhile, General William W. Loring pushed back Joseph A. J. Lightburn at Fayetteville to Charleston on September 11th. Lightburn and the staff made the plan and the dispatch was sent. Elements fought at Cotton Hill and Gauley Ferry on September 11th and again at Charleston on September 13th, slowing Loring's advance. This allowed time for an armada of packets and barges to assist evacuations during the Battle of Charleston. The flotilla of barges and civilian packets evacuated the salt miners, residents and civilian government during the "Confederate Overrun of Charleston, West Virginia". The local privateer packets had small cannons. They were alongside of the 9th at the mouth of Elk River and the 5th Infantry on the Kanawha, firing into the main Confederate columns coming down the Kanawha River until all the civil boats and barges were well underway to Point Pleasant. Then Lightburn's cavalry fought their way back to the road to Ravenswood drawing away some of Loring's cavalry while privateers blasted into the Confederate Infantry, but, was followed by Confederate field artiliary.
Having held their line, the 9th and 5th infantry began their boarding side boats and moving the skirmish line down river towards Point Pleasant. Loring's infantry fight progressed down the Kanawha shores well above the refugee fleet seemingly going to take the fight all the way to the mouth of the river. Lightburn had figured on rejoining the frontline troops at the mouth of the Kanawha where an Ohio artillery detachment set a trap for Loring's troops. Some historians have regarded this as one of the most intelligent execution of a military recall and retreat manoeuvre exercised. But, Loring knew when to stop his push. The Confederate occupation of six weeks was for the salt from which they caravan to the south to keep their meats supply from spooling.
A counter-assault took the Union some time to reorganize and was executed from October 21st to November 10th, 1862. The 9th and 5th were a part of the Union expedition up the Kanawha Valley by boat and horse. General Loring withdrew and left the salt works destroyed. Much of the 9th was stationed at Point Pleasant to January, 1863 to guard the packets and refugees.
From January to June, 1863, the 9th Infantry was ordered to Winchester and then Beverly. They scouted to Wardensville, Strasburg, and the area from April 25th to the 30th. They were at Winchester on May the 4th. The 9th marched to West Creek arriving on May 23rd and back again to Winchester June 18th. After these skirmishes and battles they were recalled to their routine sentry duty guarding river fords and towns in the Kanawha Valley until May, 1864. They were the sentry line on the West Virginia shores during the Battle of Buffington Island.
In the spring of 1864, the 9th was ordered to join George Crook's expedition against the Virginia and Tennessee Railroad which took place from May 2nd to the 19th. They took action at Cloyd's Mountain on May 9th and at New River Bridge on May 10th. Some elements were at Cove Mountain or Grassy Lick near Wytheville on May 10th, also. The 9th fought at Salt Pond Mountain and Gap Mountain on May 12th and the 13th. Soon afterwards, they were assigned to Major General David Hunter's expedition against Lynchburg from May 26 to July 1. They fought at Lexington on June 11th, moved on to battle at Diamond Hill June 17th and marched to the battle at Lynchburg on June 17 and July 18. A recall was ordered and July 9 retreated to Charleston from June 19 to July 1. Moving from there, they were at Buford's Gap June 20th and around the Salem area on June 21st.
The 9th skirmished the Shenandoah Valley from July 12th to 15th. The marched to Stephenson's Depot July 20th. They were at the Battle of Kernstown, Winchester, July 23 to 24th and Martinsburg on July 25th. Several of the best men were selected for detached service in Blazer's Scouts, a mounted unit that was to guard supply lines and combat John S. Mosby's rangers.
The 9th West Virginia Infantry was a part of Sheridan's Shenandoah Valley Campaign August from 6th to November 1st. They were at Halltown August 24 and 26 and Berryville September 3rd. They participated in the Battle of Opequon, Winchester, September 19th. They moved on to Fisher's Hill September 22nd. From there, the 9th took part in the Battle of Cedar Creek on October 19th. From there, they marched to Camp Russell and remained until November, 1864.
The 9th West Virginia was amalgamated with 5th West Virginia Volunteer Infantry Regiment on November 9, 1864, to create the 1st West Virginia Veteran Volunteer Infantry Regiment.
After the war, General Isaac H. Duval recounted, "We were in some defeats as well as many victories, and in our defeats and retreats the Ninth Regiment was never panic-stricken, but always came off as it went into battle, shoulder to shoulder. We never allowed the enemy to go through us in advancing or retreating."
