Duelling and Beresford's quarrel with the Prince of Wales

Did Beresford fight any duels?

No substantial history of duelling had been found, though he came close to a confrontation with the Prince of Wales.

No actual duel is established in the research described here. Beresford came close to a confrontation with the Prince of Wales over a scandal involving his wife Ellen Gardner and his affair with Frances Evelyn 'Daisy' Greville, Countess of Warwick. When Ellen obtained a compromising letter, her solicitor retained it despite pressure from the prince to destroy it. The prince then tried to exclude Ellen from his social circle, prompting Beresford to demand a written apology and causing a lasting rupture.
