The world's first gay, equine, military, epistolary romance. Newly discovered letters written from Wellington's warhorse (Marengo) to Napoleon's warhorse (Copenhagen) and vice versa. Includes extra material not featured in the Radio 4 series, both elements of the letters cut from the final scripts and additional material not featured in the shows at all, including the letters from Marengo to his hygienist and the horse he plays chess with, and the notes between Copenhagen and the annoying dog he has to share a stall with. Initially written as a series of letters between the authors (each choosing a stretch of the Napoleonic wars between them to examine and write into the most recent letter). They were then performed with great success at the Tall Tales evenings in Kilburn until the letters were picked up by the BBC for broadcast in autumn 2011.
