Jacob, Peter, and Perry Cline were all sons of Jacob Cline, Sr. Jacob, Sr., owned between 5,000 and 6,000 acres along the Tug River, the majority of it on the West Virginia side. One of his nearest neighbors was William Anderson "Devil Anse" Hatfield, later known as the leader of the Hatfield faction in the celebrated feud. Jacob, Sr., died in 1858, leaving his considerable land holdings and three minor sons with a considerable problem. During the war, the Tug Valley was the scene of bitter fighting between two factions, one possibly led by Lewis King, the other presumably by Devil Anse Hatfield. Judging by the fact that both of the older Cline brothers joined the 39th Kentucky much later than most of the recruits, it is possible that they simply tried to stay out of the fray. Late in 1862, a raid was run through the eastern section of Pike County and into the northwestern section of Buchanan County by pro-Confederate forces, possibly those under either Vincent Addison Witcher or Nathaniel McClure Menifee, both known to have passed through the area about this time. Several of the local men were killed, their homes burned, and their families abused and dispersed. This event convinced many of the local men from these areas to join the 39th Kentucky to try and provide some protection for their families. After the war, Jacob Cline, Sr.'s, large tract of land was passed on to Perry Cline, the youngest of the brothers who did not serve. Perry named John Dils, Jr., as his guardian even though he had lived with another family before then and up to that time. In 1877, Devil Anse sued Perry Cline over the land, alleging that the Cline brothers had illegally cut timber from his side of the property line. Whether or not this is true is debatable. It is hard to believe that Hatfield would have been able to seize 5,000 acres of land because of such a minor disagreement, but the Logan County Court may have been somewhat partisan in its decision. Perry would later play a major role in the celebrated feud, allegedly receiving the backing of John Dils, Jr., who had also suffered greatly at the hands of Devil Anse during the war. Perhaps Perry Cline and Dils both saw an opportunity to repay Hatfield for his wartime activities and his avarice. Hatfield would also lose the land later on when the county political situation would turn against him in the later stages of the feud.
