[11][12] His youngest brother, John L. Frost, also appears as a printer in Mexico, Missouri in 1860,[13] and in the 1870 and 1880 censuses before his death lived across the Mississippi River in Quincy, Illinois working first as a typesetter, then a newspaper reporter.

He later edited the Knox County (Missouri) Democrat and lived his final years with his daughter Annie in Siloam Springs, Arkansas.

[17] Frost resigned his legislative seat for military service at some time after the May 15, 1862 Confederate raid on Ravenswood, so George McC.

[18] Frost became the Lieutenant colonel of the 11th West Virginia Infantry Regiment, then led by his brother-in-law Col. John Castelli ("Cass) Rathbone, who as a civilian managed the oil company developing Burning Springs.

During CSA Gen. Albert G. Jenkins' Roane and Jackson County raid in September 1862, Confederate raiders seized Spencer (the Roane County seat) on September 2, in part because Col. Rathbone who was commanding five companies of the 11th West Virginia failed to heed General B. Kelley's warnings of their advance, so his men awoke with Confederates pointing guns at them (and fled to the woods or towards Parkersburg, and Rathbone soon surrendered with 200 men and was paroled by Jenkins).

From Wheeling, Governor Pierpont sent more men to defend Parkersburg, and Frost took command of the soldiers who had retreated from Spencer to the city.

[21] Although the documents of the U.S. Army investigation of the Spencer incident were lost, rumors abounded that Rathbone had reached a deal to protect his oil field.

Thus, after his release, Rathbone was only allowed to supervise suspected Confederate sympathizers imprisoned in Ohio, then was dismissed from the service on January 6, 1863, reportedly for cowardice during the Spencer incident.

Although Rathbone was later reimbursed for funds he had spent outfitting the 11th West Virginia Infantry and Company C of the 1st West Virginia Cavalry, he was a broken man by this and the burning of his family's oil fields at Burning Springs the following July, and after the war moved to Kansas, where he died not long afterward.

Frost also recruited Company F of the 3rd West Virginia Cavalry at Parkersburg in November 1862, eventually deploying it on scout duty in Wood, Jackson and Wirt counties.

Flesher recruited Company H of the Third (West) Virginia Cavalry patrolled the roads from Parkersburg to Ripley, Ravenswood and Belleville and would eventually be attached to the 23rd Ohio Infantry.

Pierpont on March 2 that Ritchie County railroad bridges were burned the previous night and secessionists claimed Hoy proposed to allow them including Sherrad Clemens to speak in Parkersburg.

[29] As West Virginia voters overwhelmingly voted for statehood in late March 1863 (President Lincoln recognizing the vote in April and stating that statehood would occur 60 days later in June, 1863), the "Moccasin Rangers" would be organized formally within the 19th Virginia Cavalry (under CSA Col. then (Gen.) John Imboden and William Lowther Jackson of Parkersburg).

Outposts in Roane, Wirt and Jackson Counties (even Ravenswood) were temporarily abandoned, which exacerbated bridge-burning by Confederate troops.

He asked for 3000 men to defend the railroad, 500 additional guns for new recruits and Parkersburg's cannons to be returned, with little result until mid-May.

Henry Haywood of the 18th U.S. Infantry noted his availability, Pierpont sent those troops to protect Wheeling rather than Parkersburg on May 4, so on Frost sent his son, Sgt.

On May 7 Gen. Kelley notified Pierpont that he was ordering the 14th Pennsylvania Cavalry and the 10th (West) Virginia Infantry to aid Parkersburg, and the upper Ohio Naval Command sent a second gunboat.

[33] Thus, the 9th West Virginia and 13th Kentucky militia (rather than the 11th West Virginia) defended Ravenswood during the victory at the Battle of Buffington Island which ended the raiding of CSA Major General John Hunt Morgan (although Morgan would surrender 8 days later after further defeat at the Battle of Salineville).

Frost was commanding the Third Brigade of Col. Joseph Thoburn's division when (due to poor intelligence) it encountered a large Confederate force near Snicker's Ferry, in what became known as the Battle of Cool Spring.

His youngest daughter did not survive to adulthood; his widow would live until 1886, marrying twice more, first in 1867 to Andrew Brown in Scioto County, Ohio, then in 1870 to John W. Brigham in Missouri, before moving to Cairo, Illinois (where their son Daniel V. Frost had settled) before her death.
