The manuscript is a copy of a letter in Wagnière’s hand. The author references Epître, composed by Frederick II at Erfurt on 23 September, which clearly reflects his contemplation of suicide. Voltaire praises the glory and military prowess of Frederick II of Prussia purporting to dissuade the monarch from seriously committing to such a destructive pursuit. The author also mentions The Battle of Kolín where the Austrians defeated the Prussians and draws analogies between Frederick II of Prussia and Prince Louis II de Bourbon-Condé as well as Charles XII of Sweden. Additionally, the letter cites an ending of a poem, penned by Frederick II and featured in D7414.
