Question:
Christopher Houston Carson (December 24, 1809 - May 23, 1868), better known as Kit Carson, was an American frontiersman. He was a mountain man (fur trapper), wilderness guide, Indian agent, and U.S. Army officer. Carson became a frontier legend in his own lifetime via biographies and news articles. Exaggerated versions of his exploits were the subject of dime novels.
In 1845, Carson guided Fremont on their third and last expedition. They went to California and Oregon. Fremont made scientific plans, but the expedition appeared to be political in nature. Fremont may have been working under secret government orders. President Polk wanted the province of Alta California for the United States. Once in California, Fremont started to rouse the American settlers into a patriotic fever. The Mexican government ordered him to leave. Fremont went north to Oregon, though not before instigating the Sacramento River massacre, in which at least 150 Indians were killed in an unprovoked attack. The party moved up along the Sacramento River, continuing to kill Indians as they went, then camped near Klamath Lake. Messages from Washington, DC made it clear that President Polk wanted California. At Klamath Lake in southern Oregon, Fremont's party was hit in a revenge attack by 15-20 Indians on the night of May 9, 1846. Two or three men in camp were killed. The attackers fled after a brief struggle. Carson was angry that his friends had been killed. He took an axe and avenged the death of his friends by chopping away at a dead Indian's face. Fremont wrote, "He knocked his head to pieces." In retaliation for the attack, a few days later Fremont's party massacred a village of Klamath people along the Williamson River in the Klamath Lake massacre. The entire village was razed and at least 14 men, women and children were killed. There was no evidence that the village in question had anything to do with the previous attack.

input: Assange visited Sweden in August 2010. During his visit, he became the subject of sexual assault allegations from two women with whom he had sex. He was questioned, the case was initially closed, and he was told he could leave the country. In November 2010, however, the case was re-opened by a special prosecutor who said that she wanted to question Assange over two counts of sexual molestation, one count of unlawful coercion and one count of "lesser-degree rape" (mindre grov valdtakt). Assange denied the allegations and said he was happy to face questions in Britain. In 2010, the prosecutor said Swedish law prevented her from questioning anyone by video link or in the London embassy. In March 2015, after public criticism from other Swedish law practitioners, she changed her mind and agreed to interrogate Assange in the Ecuadorian embassy in London, with interviews finally beginning on 14 November 2016. These interviews involved police, Swedish prosecutors and Ecuadorian officials and were eventually published online. By this time, the statute of limitations had expired on all three of the less serious allegations. Since the Swedish prosecutor had not interviewed Assange by 18 August 2015, the questioning pertained only to the open investigation of "lesser degree rape", whose statute of limitations is due to expire in 2020. On 19 May 2017, the Swedish authorities dropped their investigation against Assange, claiming they could not expect the Ecuadorian Embassy to communicate reliably with Assange with respect to the case. Chief prosecutor Marianne Ny officially revoked his arrest warrant, but said the investigation could still be resumed if Assange visited Sweden before August 2020. "We are not making any pronouncement about guilt", she said.

Answer the question at the end by quoting:

Migration Period art denotes the artwork of the Germanic peoples during the Migration period (ca. 300-900). It includes the Migration art of the Germanic tribes on the continent, as well the start of the Insular art or Hiberno-Saxon art of the Anglo-Saxon and Celtic fusion in the British Isles. It covers many different styles of art including the polychrome style and the animal style.
In the 3rd century the Roman Empire almost collapsed and its army was becoming increasingly Germanic in make-up, so that in the 4th century when Huns pushed German tribes westward, they spilled across the Empire's borders and began to settle there. The Visigoths settled in Italy and then Spain, in the north the Franks settled into Gaul and western Germany, and in the 5th century Scandinavians such as the Angles, Saxons and Jutes invaded Britain. By the close of the 6th century the Western Roman Empire was almost completely replaced with smaller less politically organized, but vigorous, Germanic kingdoms. Although these kingdoms were never homogeneous, they shared certain common cultural features. They settled in their new lands and become farmers and fishermen. Archaeological evidence shows no tradition of monumental artwork, such as architecture or large sculpture in permanent materials, but a preference instead for "mobile" art for personal display, usually also with a practical function, such as weapons, horse harness, tools, and jewelry which fastened clothes. The surviving art of the Germanic peoples is almost entirely personal adornment, portable, and before conversion to Christianity was buried with its owner. Much art in organic materials has no doubt not survived. Three styles dominate Germanic art. The polychrome style originated with the Goths who had settled in the Black Sea area. The animal style was found in Scandinavia, north Germany and England. Finally there was Insular art or the Hiberno-Saxon style, a brief but prosperous period after Christianization that saw the fusion of animal style, Celtic, Mediterranean and other motifs and techniques.
