MacGregor mounted an aggressive sales campaign. He gave interviews in the national newspapers, engaged publicists to write advertisements and leaflets, and had Poyais-related ballads composed and sung on the streets of London, Edinburgh and Glasgow. His proclamation to the Poyers was distributed in handbill form. In mid-1822 there appeared in Edinburgh and London a 355-page guidebook "chiefly intended for the use of settlers", "Sketch of the Mosquito Shore, Including the Territory of Poyais"—ostensibly the work of a "Captain Thomas Strangeways", aide-de-camp to the Cazique, but actually written either by MacGregor himself or by accomplices.
