loot that set the tone of the war. Nowhere else, with the grim exception of the East Kentucky and East Tennessee mountains, did the Civil War degenerate so completely into a squalid, murderous, slugging match as it did in Kansas and Missouri." The most infamous event in this war of raids and reprisals was Confederate leader William Quantrill's raid on Lawrence, Kansas, known as the Lawrence Massacre. In response to Quantrill's raid, the Union command issued General Order No. 11 (1863), the forced depopulation of specified Missouri border counties. Intended to eliminate sanctuary and sustenance for pro-Confederate guerrilla fighters, it was enforced by troops from Kansas, and provided an excuse for a final round of plundering, arson, and summary execution perpetrated against the civilian population of western Missouri. In the words of one observer, "the Kansas–Missouri border was a disgrace even to barbarism." Different meanings As the war continued, the "Jayhawker" term came to be used by Confederates as a derogatory term for any troops from Kansas, but the term also had different meanings in different parts of the country. In Arkansas, the term was used by Confederate Arkansans as an epithet for any marauder, robber, or thief regardless of Union or Confederate affiliation. In Louisiana, the term was used to describe anti-Confederate guerrillas; in Texas, free-booting bands of draft dodgers and deserters. Over time, proud of their state's contributions to the end of slavery and the preservation of the Union, Kansans embraced the "Jayhawker" term. The term came to be applied to people or items related to Kansas. Relationship to the University of Kansas Jayhawk When the University of Kansas fielded their first football team in 1890, the team was called the Jayhawkers. Over time, the name was gradually supplanted by its shorter variant, and KU's sports teams are now exclusively known as the Kansas Jayhawks. Historic descriptions of the ornithological origin of the "Jayhawker" term have varied. Writing on the troubles in Kansas Territory in 1859, one journalist stated the jayhawk was a hawk that preys on the jay. One of the "Jayhawkers of '49" recalled that the name sprang from their observation of hawks gracefully sailing in the air until "the audience of jays and other small but jealous and vicious birds sail in and jab him until he gets tired of show life and slides out of trouble in the lower earth."
