A recently discovered notebook from 1799 provides a rare and unfiltered look at Admiral Horatio Nelson's command style, revealing an authoritative side previously unseen in official correspondence. The document, which belonged to Captain Henry D'Esterre Darby of HMS Bellerophon, contains 46 naval commands issued by Nelson or on his behalf.

Approximately 40 of these orders are believed to have never been made public before, offering insights into the day-to-day mechanics of naval operations during a period of intense conflict. The commands cover a range of issues, from intelligence gathering on enemy fleets and casualty reports to the distribution of wine for morale and restrictions on communication.

Central to the collection is the court-martial and subsequent execution order for William White, a boatswain's mate aboard the HMS Bellerophon. White was tried for mutinous conduct, including threatening an officer. The court sentenced him to death by hanging, a sentence Nelson formally directed to be carried out.

Experts describe the notebook as offering a "vivid image of Nelson as a war-time commander" who was "principally concerned with authority." This contrasts with his public image, which often emphasizes his humanity and battlefield successes. The orders are described as "unfiltered and urgent," providing a stark contrast to the carefully crafted language of official dispatches.

The 'extraordinary' notebook shows an 'authoritative' side of Britain's most famous sea lord, the likes of which have not been seen before, experts said.

The year 1799 was also a period of personal controversy for Nelson, as he was engaged in an affair with Emma, Lady Hamilton, the wife of the British ambassador to Naples. The notebook's contents reflect the pressures of wartime command alongside the political and personal complexities of the era.

Described as being 'unfiltered and urgent', the commands written by the Admiral offer a different glimpse of Nelson to the image typically seen in official correspondence.

The manuscript, valued at £18,000, is being sold by rare books specialist Arch Books and is expected to enter a trust rather than a private collection. Arch Books noted the manuscript's "exceptional rarity and importance," highlighting its preservation of Nelson's "sense of justice, morale and command."
