Chapter 3 analyzes how, within a newly expanded marketplace for print, a combination of manuscript and printed letters helped shape the ways in which the Company of Scotland’s Darien venture (1695–1700) and its subsequent failure came to be understood in cultural memory. Letters in both manuscript and printed form helped establish the company. Letters also served to connect the company directors with the colonists in Darien, and, when published in pamphlet form, they provided information and propaganda about the new colony to the nation back home. After the collapse of the Darien settlement, letters also became the evidence used to shape the cultural memory of the disaster. The chapter traces how, over the course of the eighteenth century, the cultural memory of Darien was erased by the bigger controversies surrounding the implications of the Acts of Union (1707) for the Scottish nation. Lastly, it considers how the rediscovery and publication of the Darien papers by John Hill Burton in 1849 brought them back into focus as a site of cultural memory.
