Some context: Guy Carleton, 1st Baron Dorchester, KB (3 September 1724 - 10 November 1808), known between 1776 and 1786 as Sir Guy Carleton, was an Anglo-Irish soldier and administrator. He twice served as Governor of the Province of Quebec, from 1768 to 1778, concurrently serving as Governor General of British North America in that time, and again from 1785 to 1795. The title Baron Dorchester was created on 21 August 1786. He commanded British troops in the American War of Independence, first leading the defence of Quebec during the 1775 rebel invasion and the 1776 counteroffensive that drove the rebels from the province.
In August 1783, Carleton was informed that Great Britain would grant the United States its independence. With his exit from New York imminent, Carleton asked to be relieved of his command. With this news, Loyalists began an exodus from the Thirteen Colonies and Carleton did his best to have them resettled outside the United States.  At a meeting with George Washington, among others, to arrange for the implementation of those parts of the Treaty of Paris relating to the evacuation of New York City, then commanded by Carleton and still occupied by the British Army, many Loyalists and former slaves, Carleton refused to deliver over the human property to the Americans at the time of the British evacuation. Instead, he proposed a registry so that "the owners might eventually be paid for the slaves who were entitled to their freedom by British Proclamation and promises."  Sir Guy noted that nothing could be changed in any Articles that were inconsistent with prior policies or National Honour. He added that the only mode was to pay for the Negroes, in which case justice was done to all, the former slaves and the owners. Carleton said that it would be a breach of faith not to honour the British policy of liberty to the Negro and declared that if removing them proved to be an infraction of the treaty, then compensation would have to be paid by the British government. To provide for such a contingency, he had a register kept of all Negroes who left, called the Book of Negroes, entering their names, ages, occupations, and names of their former masters. The Americans agreed to this, but as far as can be determined, the Crown never paid compensation. The British transported about 3,000 freedmen and other Loyalists to Nova Scotia for resettlement. As the colony struggled, some of the freedmen later chose in the early 1790s to go to Freetown, Sierra Leone, where the British set up a new colony, which included the Black Poor from London.  Washington disagreed with Sir Guy's actions and wrote: "...the measure is totally different from the letter and spirit of the Treaty but waiving the specialty of the point, leaving this decision to our respective Sovereigns I find it my duty to signify my readiness in conjunction with you to enter into agreements, or take any measures which may be deemed expedient to prevent the future carrying away any Negroes or other property of the American people."  On 28 November, the evacuation was finished, and Carleton returned to England. John Campbell of Strachur succeeded him as Commander-in-Chief, North America, although the post was then much reduced in scope.

Some context: Mumford & Sons are a British band formed in 2007. The band consists of Marcus Mumford (lead vocals, electric guitar, acoustic guitar, drums), Ben Lovett (vocals, keyboard, piano, synthesizer), Winston Marshall (vocals, electric guitar, banjo) and Ted Dwane (vocals, bass guitar, double bass). Mumford & Sons have released three studio albums: Sigh No More (2009), Babel (2012) and Wilder Mind (2015).
Mumford & Sons released their second studio album Babel on 24 September 2012, with a track listing of 12 songs, and a deluxe edition containing three exclusive songs. The lead single "I Will Wait" premiered on Zane Lowe's BBC Radio 1 show on 7 August. On 29 August 2012, Mumford & Sons recorded their concert at Red Rocks Amphitheatre in Colorado. The Concert was later released on DVD, Vinyl and on iTunes as "Road to Red Rocks". The performance of "I Will Wait" from the concert was released ahead of the DVD on 9 September as the band's official video for the song. On 22 September 2012, the band performed two songs from the new album, "I Will Wait" and "Below My Feet", on Saturday Night Live.  Babel debuted at number one on the UK Albums Chart and the US Billboard 200. It became the fastest selling album of 2012 in the UK, selling over 158,000 copies in its first week, and was the biggest selling debut of any album in 2012 in the US, selling 600,000 in its first week, and over a million worldwide. In December 2012, Winston Marshall told NME that the band was rehearsing and writing for their next album.  The first phase of a 2013 world tour in support of Babel was released in November 2012. Their Gentlemen of the Road tour continued through 2013. After performing two shows on 8 & 9 June 2013 at the Austin360 Amphitheater in Austin, Texas, bassist Ted Dwane checked into a hospital the next day. Surgeons found a blood clot on the surface of his brain and performed surgery to remove it. Heeding medical advice to aid Dwane's recovery, the band cancelled the rest of its Summer Stampede Tour, including performances at the 2013 Bonnaroo Music Festival and returned to the UK. Dwane's surgery was successful, and his recovery was such that the band were able to headline the 2013 Glastonbury Festival on 30 June, with the band receiving acclaim for their performance.  After first including select stopover cities in their 2012 Tour, the band again selected five cities in Canada, the UK and US to host a two-day festival with shows on multiple stages as well as various other activities and performances. The first stopover of the 2013 Gentleman of the Road tour was in Lewes, East Sussex, from 19 to 20 July. Next was Simcoe, Ontario from 23 to 24 August, followed by Troy, Ohio from 30 to 31 August. The band rounded out their tour with stopovers in Guthrie, Oklahoma on 6 and 7 September and finally St. Augustine, Florida on 13 and 14 September. The Vaccines, Edward Sharpe & the Magnetic Zeros, Vampire Weekend, Old Crow Medicine Show, Yacht Club DJs, Alabama Shakes and various other bands also performed at many of the stopovers throughout the tour.  After the end of the Babel tour, Mumford and Sons took a five-month break before returning to the studio in February 2014 to start work on their third album.
